Standards Frequently Asked Questions - BICSI

This question continues to come up. It is believed these misunderstandings relate to several reasons: 

Check now

• Publication of an ISO/IEC technical report that addresses cabling mitigation techniques and cabling distance limitations for installed class E/category 6 cabling.
• Publication of a TIA technical systems bulletin that addresses cabling mitigation techniques and cabling distance limitations for installed category 6 cabling.
• Publication of an ISO/IEC standard that addresses augmented class e/category 6 (class Ea / category 6a) cabling requirements without cabling distance limitations below 100 m.
• Publication of a TIA standard that addresses augmented Category 6 (Category 6A) cabling requirements without cabling distance limitations below 100 m.
• Table 55-12 located in the IEEE 802.3an- standard.
• Manufacturer marketing claims of distance-limited applications support of 10GBASE-T.

In this reply, we cannot address individual cabling system manufacturers claims of "short-reach" support for 10GBASE-T however we can offer standards-based guidance as it relates to the 10 Gigabit Ethernet application. The bottom line is, if you desire to achieve 10GBASE-T support up to 100 m without the need for potentially costly mitigation techniques, you must specify and install class Ea/category 6a or higher cabling system products that fully comply with ISO/IEC - Ed.2.0 Amendment 1, "Information technology - Generic cabling for customer premises - Amendment 1" and ANSI/TIA-568-B.2-10, "Transmission Performance Specifications for 4-pair 100 ohm Augmented Category 6 Cabling."

Additional Details

10GBASE-T Background 
In , the IEEE published the IEEE 802.3an- standard known as "IEEE Standard for Information technology—Telecommunications and information exchange between systems—Local and metropolitan area networks—Specific requirements  Part 3: Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer Specifications  Amendment 1: Physical Layer and Management Parameters for 10 Gb/s Operation, Type 10GBASE-T."  This standard has defined several classifications/categories of cabling with associated length limitations.  In , class E/category 6 (screened and unscreened) and class F/category 7 (screened) cabling standards existed as referenced in Table 55-12 (below). When IEEE 802.3an- published, the class Ea/category 6a and class Fa/category 7a cabling standards had not yet published. Both have since published.

IEEE 802.3an-, Table 55-12, Cabling Types and Distances

Cabling Supported link segment distances Cabling references Class E / Category 6 55 m to 100 m* ISO/IEC TR- / TIA/EIA TSB-155 Class E / Category 6: unscreened 55 m 0 / TIAISO/IEC TR-/EIA TSB-155
Class E / Category 6: screened 100 m ISO/IEC TR- / TIA/EIA TSB-155 Class F / (Category 7) 100 m ISO/IEC TR- Class EA / Category 6A 100 m ISO/IEC Ed 2.1 / TIA/EIA-568-B.2-10

*Supported link segments up to 100 m shall meet the alien crosstalk to insertion loss requirements specified in 55.7.3.1.2 (PSANEXT) and 55.7.3.2.2 (PSANEXT loss to insertion loss ratio requirements).

Interpretation of IEEE 802.3an-, Table 55-12 
The first reference to class E/category 6 cabling offers a supported link segment distance of 55 m to 100 m. The reason this wide range is offered is to accommodate two types of class E/category 6 cabling; screened and unscreened. As you look further down the table, note that unscreened class E/category 6 cabling is distance limited up to only 55 m while screened class E/category 6 cabling appears to support the 10GBASE-T application out to 100 m. The key to understanding these length limitations is to understanding the implications of the cabling references which are also listed in the table.

Understanding the purpose of ISO/IEC TR- 
ISO/IEC TR- is a technical report known as "Information Technology - Assessment and mitigation of installed balanced cabling channels in order to support 10GBASE-T." As the title implies, this report was written because, at the time, the subject of 10GBASE-T compliant cabling was still under technical development and there was no immediate possibility of an agreement on an International Standard. This report provides guidance regarding installed class E channels and whether they will support 10GBASE-T. This report also provides mitigation procedures to improve the performance of class E channels to the point where the application is supported. class F and class Fa cabling, according to ISO/IEC :, will support 10GBASE-T without mitigation up to 100 m. The support of 10GBASE-T includes additional parameters and an extended frequency range (1-500 MHz) beyond class E (1-250 MHz). Conformance of installed cabling beyond the original cabling specifications must be determined on a case by case basis, and is primarily needed due to new external noise requirements. Whether these requirements are met by a specific channel is influenced by the components and installation practices used. As 10GBASE-T uses frequencies above those specified for class E of ISO/IEC , input from supplier and installer may be helpful to evaluate the performance of installed class E channels.

ISO/IEC TR- Mitigation Techniques 
Depending on the components used and the layout of the cable and connecting hardware, some transmission parameters may not be met. A critical transmission parameter is power sum alien crosstalk. For channels which are to be requalified in the field to troubleshoot problems, the manufacturer should be consulted regarding mitigation techniques or the following actions should be taken:

1. Replace patch cords with higher categorized patch cords.
2. Remove cable bundle ties, and to the extent possible, randomize the cables at the near end.
3. Replace the patch panel with a higher category patch panel.
4. Reduce the number of cabling components.
5. Replace the cabling.

The mitigation techniques described above can significantly impact the cost of an installation and it's important to note that any movement of or changes to the installed cabling system components may result in another round of mitigation techniques for further troubleshooting.

Understanding the purpose of TIA/EIA TSB-155 
TIA/EIA TSB-155 is a technical bulletin known as "Guidelines for the Assessment and Mitigation of Installed Category 6 Cabling to Support 10GBASE-T." The guidelines of this Telecommunications Systems Bulletin (TSB) contain additional recommendations to further characterize existing category 6 cabling plant as specified in ANSI/TIA/EIA-568B.2-1 for supporting 10GBASE-T applications. This TSB includes field test procedures and field tester guidelines that can be used for this assessment. This TSB describes additional guidelines to support the IEEE 802.3an 10GBASE-T standard for using installed 100 ohm, 4-pair category 6 cabling meeting the requirements of ANSI/TIA/EIA-568-B.2-1. This TSB characterizes the crosstalk coupling between 4-pair category 6 cabling in close proximity referred to as alien crosstalk and provides additional guidelines for field test equipment and field test methods and alien crosstalk mitigation. These guidelines provide additional information on the extended frequency transmission performance expected of category 6 cabling from 250 MHz to 500 MHz. The transmission parameter recommendations included in TSB-155 provide a means to assess installations of installed category 6 cabling, as specified in ANSI/TIA/EIA-568-B.2-1 and corresponding addenda, up to and including 500 MHz and for the additional parameters necessary to support 10GBASE-T.

TIA/EIA TSB-155 Mitigation Techniques 
The following procedures may be applied to channels with insufficient alien crosstalk margin. Select the option(s) that is most appropriate for your situation.

1. When selective deployments of 10GBASE-T applications are possible, utilize nonadjacent patch panel positions (patch panel adjacency should also be checked at the rear of the patch panel), separate the equipment cords and unbundle the horizontal cables.
2. When deploying 10GBASE-T applications in adjacent patch panel positions, in the telecommunications room, testing is recommended. The number of disturbed channels to be tested should be determined using statistical sampling techniques based upon the intended confidence level.
   
   1. Identify measured patch panel positions to be included in the power sum.
   2. Select and test those channels with connectors adjacent to, or cable segments in the same bundle as, the disturbed channel. For these channels, test the alien crosstalk to be included in the power sum calculation following the procedures in clause A.8.
3. In the event that the alien crosstalk transmission parameters given in either 6.1 or 6.2 are not met in step 2 the alien crosstalk may be mitigated by the following procedure.
   
   1. Reduce the alien crosstalk coupling by separating the equipment cords, the patch cords and un-bundling the horizontal cable.
   2. An alternative to separating equipment cords is to utilize equipment cords sufficiently specified to mitigate the alien crosstalk coupling such as category 6 ScTP cords or category 6a cords.
   3. Reconfigure the cross-connect as an interconnect
   4. Replace connectors with category 6a connectors
   5. Replace the horizontal cable with category 6a horizontal cable

The channel performance after mitigation should be verified, in fact, the channel performance should be verified after any movement of or changes to the installed system because changes in the physical geometry of the installed class E/category 6 cabling may alter the previously reported transmission performance characteristics. Once again, the mitigation techniques described above can significantly impact the cost of an installation and it's important to note that any movement of or changes to the installed cabling system components may result in another round of mitigation techniques for further troubleshooting. As previously suggested, the bottomline is if you desire to achieve 10GBASE-T support up to 100 m without the need for potentially costly mitigation techniques, you must specify and install class Ea/category 6a or higher cabling system products that fully comply with ISO/IEC - Ed.2.0 Amendment 1 known as "Information technology - Generic cabling for customer premises - Amendment 1" and ANSI/TIA-568-B.2-10, "Transmission Performance Specifications for 4-pair 100 ohm Augmented Category 6 Cabling."

Cabling standards do not necessarily provide pros and cons of installation methodologies such as the use of trunking assemblies or field termination of cabling components. While not necessarily a complete list, please consider the following;

Trunking Cons

Cost — The installed cost of trunking assemblies may be higher than the installed cost of field terminated cabling. This potentially applies to both optical fiber and balanced twisted-pair cabling.
Lead time — The factory lead time of trunking assemblies may be longer than the lead time associated with the purchase of cabling components required to field terminate the same cabling. This applies to both optical fiber and balanced twisted-pair cabling.

Trunking Pros

Rapid Deployment — Installations may be quicker once trunking assemblies are on-site, potentially reducing on-site installation time by up to 75 percent, some manufacturers claims. The rapid deployment is potentially achieved by reducing the labor associated with pulling and placing cabling as well as cable dressing time. Trunking assemblies may be an ideal solution for installations that are time critical.
Risk Abatement  — By eliminating field terminations, there is potentially less risk of improperly terminated connections on-site when compared to field terminations. Trunking assemblies may improve the quality of the installation by removing installer variability.
Assuring High Performance — Factory termination and factory testing of trunking assemblies may minimize delays associated with on-site troubleshooting and cabling rework challenges.
Greater Predictability — Installation schedules may be completed with greater predictability when using trunking assemblies. Trunking assemblies may be an ideal solution for installations where standardization is valued. Trunking assemblies are assembled in a controlled factory environment with consistent processes potentially reducing variability which may affect transmission performance, particularly 10 Gigabit Ethernet and beyond.
Comprehensive Solution — Trunking assemblies may be purchased with a complete set of components including cable, connectors, jumpers, enclosures and racks. This potentially applies to both optical fiber and balanced twisted-pair cabling. For optical fiber trunking assemblies, a complete suite of cabling products are potentially available for use including OM1, OM2, OM3, OM4, OS1 or OS2 optical fiber cabling. For balanced twisted-pair cabling, a complete suite of cabling products are potentially available for use including categories 3, 5e, 6, 6a, 7 and 7a constructed with UTP, F/UTP (category 3 through category 6Aa) or S/FTP (category 7 and 7a) cabling components.
Aesthetically Appealing — Trunking assemblies provide a consistent, clean appearance that may improve manageability as the trunks are pulled or placed in cabling pathways.

Cabling standards provide us with two important transmission performance criteria as it relates to mixing and matching or matched telecommunications cabling components and cabling systems. Cabling standards assure both backwards compatibility and interoperability. The backwards compatibility assurance provides some degree of confidence when a higher category or type of connectivity (e.g., patch panel connectivity) is placed onto a lower category or type of cable (e.g., category 6 with category 5e or OM2 with OM3), the combination of the two different levels of transmission performance will operate to the lesser of the two levels. The important point is that they will operate. The interoperability assurance provides some degree of confidence that when you attach the connectivity (e.g., patch panel) of one manufacturer onto cable of another manufacturer, the combination of the two different manufacturers products will operate to at least the minimum transmission performance requirements of the cabling standards. Once again, the important point is that they will operate.

Cabling standards transmission requirements (e.g., connecting hardware, cable, links and channels) establish minimum performance expectations that are independent of product branding. Cabling systems manufacturers on the other hand may use these benchmark transmission performance requirements in order to establish higher transmission performance guarantees that exceed industry standards. Transmission performance that exceeds the industry standards benchmarks are generally described as performance margin. In some cases, cabling systems manufacturers will offer a mix and match system approach to marketing their cabling systems. In other cases, cabling systems manufacturers will offer a matched system approach to marketing their cabling system. Either way, as a specifier or decision maker of cabling systems, you are entitled to compare the mixed or matched systems and to do so on a level playing field using transmission performance margins versus the minimum requirements of the standards as your benchmark.

In optical fiber cabling systems and balanced twisted-pair cabling systems, there are many factors that contribute to optimized transmission performance. These factors include:

• Individual component performance and margin to standards.
• Optical or electrical cabling connector interface characteristics.
• Methods that manufacturers use to achieve optimum performance.
• Frequency range or bandwidth within which individual components are optimized to perform.

Perhaps the single most critical of these factors towards achieving optimal transmission performance has to do with the optical or electrical cabling connector interface characteristics. In the case of optical fiber cabling, the interface in question involves the end face geometry of the optical fiber ferrules, the cleanliness and polish of the end face and the optical fiber adapter sleeves that align the two optical fiber connectors. In balanced twisted-pair cabling systems, the interface in question involves the plug socket interface. In optical fiber cabling and balanced twisted-pair cabling, it is possible to design and manufacture connecting hardware in such a way as to tune the components in order to optimize their transmission performance characteristics. When these cabling connector interfaces are optimized, they generally yield higher transmission performance characteristics than similar components that are not specifically optimized to work together. Ultimately, as previously suggested, as a specifier or decision maker of cabling systems, you are entitled to compare the mixed or matched systems and to do so on a level playing field using transmission performance margins versus the minimum requirements of the standards as your benchmark.

                  Low Voltage Cable (LV Cable)  Complete Buying Guide

Chapter 1: Introduction to Low Voltage Cable

A low voltage cable which is popularly known as LV cable is a special type of cable that is mainly used for transferring a relatively low amount of voltage.

These cables are made of stranded aluminum or copper conductors although some feature solid and tinned conductors.

Steel wires and aluminum tape is usually applied on the outer sheath to give the conductor a significant level of mechanical protection.

Thermoplastic materials are usually used as insulators for the Low Voltage Cable. Some of these materials include XLPE, PVC, and even HFFR.

Chapter 2: Uses of Low Voltage Cable

Low Voltage Cables are used in electrical equipment and appliances whose voltage rating is between 50 to V. These cables are made of aluminum though some are made of tinned copper.

Some of the most common applications of LV cable include:

-: Most businesses and even residential areas still have wired telephones. These equipment use Low Voltage Cables to complete their connections for efficient communication

-Ethernet and Wi-Fi: Wi-Fi and Ethernet setups use Low Voltage Cables for ensuring the networks perform to the optimum level.

-Security and surveillance systems: Low Voltage Cables are used in wiring and mapping security systems for surveillance. They connect different components of the surveillance systems such as cameras to the main operating system.

For lighting: Lighting systems for domestic and commercial applications tend to use low voltage cables. These cables are even an ideal solution for outdoor lighting setups such as floodlights. -For sound systems: Sound systems that are designed for public audiences tend to enjoy the power of low voltage cables. -For renewable energy: Most renewable energy sources such as solar deploy the effectiveness of low voltage cables. These Low Voltage Cables are ideal for transmitting and distributing energy from these sources. -Instrumentation: Low Voltage Cables are used for controlling different instruments in major installations. These cables are commonly found in the automotive, water vessels and even air vessels.

Chapter 3: Installation of Low Voltage Cable

If you are planning to buy LV cable, it is obvious that you are thinking of the most effective ways of doing the installation. It is important to choose the safest and most effective ways of installing these cables.

Here are the main methods for installing LV cable:

1. Underground installation of low voltage cables

In this method of installation, LV cable is directly laid on the ground then is covered with 100mm thick sand. The most preferred depth of the ground is 650mm. Concrete tile is then laid over continuously along the route of the cable so as to provide extra protection.

You can add cable markers at interval points along the path for identification. Try to minimize the bending of the cable during the installation phase.

Underground installation of LV gives you the opportunity to install more than one cable. This is the best option if more than one cable is designed to pass through the same path. In this type of installation, it is advisable to position them horizontally and leave a space of at least 150mm apart. Ensure that each group of cable is properly marked.

You should have enough markers for the underground LV installation. These markers should be at least 75 meters apart and should be visible above the ground. On the markers, indicate the route and the depth of the cables on these markers.

2. LV Cable buried underground but in PVC pipe

Although this method of installation is similar to the direct underground installation, the difference is here we are involving PVC pipes. Here the installation can be deeper than the direct underground installation. This is because of the extra protection that is provided by the pipe.

Here, the minimum depth of installation is 60cm below the ground. Encased concrete can then be used to cover the cable once you are done with the installation.

The diameter of the PVC pipes should allow all the cables to fit inside. It is usually recommended that the diameter should not be less than 150mm. Apart from the PVC, the pipes can also be made of clay which is encased with plastic or any other weather-proof material.

3. LV cable installation above the ground

You can easily install an LV cable above the ground. This is where you can access the cable easily or without putting many struggles. There are various methods of installing an LV cable above the ground. The most common ones include PVC pipes, on cable trays, and on ladder trays.

Alternatively, you can use cleats to support the cables above the ground. These cleats have a galvanized strap that conforms to the international standard. You only need to ensure that the cleats do not exert excess pressure to the extent of causing some damage.

When it comes to the over the ground LV installation, you can do both vertical and horizontal installation. This means that the cables can be installed on the floor or even on the walls.

Apart from the cleats and trays, you can use PVC pipes to protect the cables.

From these methods of cable installation, which one should you use? You can choose whichever method that you want to depend on your situation or work environment.

If you are not sure, you should seek advice from technicians regarding the best ways of installing LV cable.

Chapter 4: Technical Specifications for Low Voltage Cables

All the low voltage cables for sale in the market tend to have physical and chemical properties. These characteristics are derived from the technical specifications of the cables.

When buying a low voltage cable in China, one of the first things that you should look at is its technical specifications. They will help you choose the right cable.

Here are some of the key specifications for low voltage cables.

-Operating temperature: Here you will know the maximum and the minimum temperature under which the cables should operate. A cable can have a minimum temperature of -10C and a maximum temperature of +30C. -Air humidity: The levels of humidity can affect the performance of a low voltage cable. A responsible LV cable manufacturer should specify the humidity range of the cable. -Standards: The cable should be manufactured according to the required international standards. One of these standards is the IEC. The manufacturer should specify all the standards on the cable. -Conductor: The manufacturer should give technical details about the conductor that is used in the cable. From this technical information, you will be able to know the performance of the cable. -Insulating properties: There should be detailed technical specifications about the insulator that is used on the cable. -Core colors: Normally, cables have different colors for phase identification. These colors are Red Yellow and Blue. The manufacturer should properly label these colors according to their respective phases. -Metallic armor of the cable: If the LV cable has more than one core, there should be armor to provide some shield. The manufacturer should properly indicate the properties of the metal armor that are being used including its standards. -Filler and bedding: The manufacturer should specify the filler and bedding for the low voltage cable. These two components are usually assembled around a conductor. -Weight of the cable: The manufacturer should clearly state the weight of the LV cable per kilometers. This technical data will help you choose the right method of low voltage cable installation.

Once you are familiar with these technical data, choosing the right LV cable will be quite easy.

4.1. Factors to Consider When Buying a Low Voltage Cable

When buying a low voltage cable in China, there are quite a number of facts that you need to consider.

These factors include

1. Area of application

You should first consider what you are going to use the cable for. This is because different Low Voltage Cables are designed for different applications.

Some Low Voltage Cables are perfectly designed for lighting, others for audio functions and others are for instrumentation.

By knowing your specific area of application, you will be in a good position to choose a low voltage cable which will meet your requirements.

2. Carrying capacity

Also known as the Ampacity which stands for ‘ampere capacity’, this is the amount of current that the cable can comfortably convey.

Different cables have different ampacity and this boils down to their respective areas of applications.

If the application requires a certain amount of current, the cable should be able to meet this need.

Once you know the amount of current that you will need, you should narrow down your choice of cables based on their carrying capacities.

After all, you cannot run large amounts of electric through a cable that has a low capacity.

3. Type of insulation

You should always consider the type of insulation that is on the low voltage cable for sale.

With competitive price and timely delivery, zhuhaicable sincerely hope to be your supplier and partner.

This is important because different insulating materials for the Low Voltage Cables have different levels of performance when exposed to a different environment.

If you are planning to install the cable in a low-hazard area, you may consider going for cables that have thin insulating material.

If you are planning to install the cable in water or humid environment, you will consider the insulating material that can survive in such places

If you will install the cable in an area where it will be exposed to water, oil and other physical elements, you should buy cables that have thick and tough insulating material.

4. Length of the cable

Before buying an LV cable, you should check on its length. Usually, the project that you are working on will determine the length of the LV cable that you should buy.

It is always advisable to buy long LV cable. This is because they tend to offer minimal resistance as compared to the shorter cables.

It is also advisable to use one long cable instead of connecting or joining many shorter cables. Joining many short cables will increase the resistance of the whole cable.

5. The number of strands

Checking the strand count is another key factor that you should consider when buying a low voltage cable in China. A strand count is simply the number of individual strands that are inside the cable.

Strand count is an important factor to consider because it affects the flexibility of the conductor. Cables that have have a high strand count tend to be more flexible than those with low strand count.

6. The flexibility of the low voltage cable

Regardless of your area of application, you will always yearn to buy flexible low voltage cable.

You are free to install a flexible low voltage cable anywhere without straining. Such cables can fit into the smallest spaces and challenging angles.

The main issue with insulation is it can affect the insulation and even the carrying capacity of the cable. You are also likely to pay a higher price tag for the flexible cable.

You may even have to trade off flexibility and ampacity of the LV cable. Highly flexible Low Voltage Cables tend to have a low current-carrying capacity.

7. The cost of LV cable

You need to find out the economic sense of LV cable for sale. Get all the information that you need about the price of low voltage cable in China.

There are various factors that determine the price of the low voltage cable. Usually, you pay for what you get. This means that high-quality Low Voltage Cables tend to be pricier than the average cables.

Check the specifications of the cables to see whether you are getting the real value of your money. Even if you are planning to buy affordable LV cable in China.

The best way of getting pricing information is by talking directly to the LV cable manufacturer in China.
