New Standards for Cabling and Category 8 Update

20 May 2017

Data Cabling, Cat5e Cat6/6a Cabling, Washington DCThe selection of proper cabling has become more crucial and also more complicated, but the process can be made easier by knowing about the choices available and updates regarding the development of Category 8 (CAT 8).

There are several organizations that determine the standards for cabling, such as the ISO (International Organization for Standardization), IEC (International Electrotechnical Commission), TIA (Telecommunications Industry Association), and CENELEC (European Committee for Electrotechnical Standardization). However, our discussion will primarily focus on ISO/IEC and TIA.

As its standard calls for 10Gb/s rates of transmission, 10GBASE-T cabling is the fastest in the market. Unable to support 10Gb/s, Category 5e does not receive 10GBASE-T standard recognition.  In addition, advisories by the TIA and ISO/IEC and TIA state that new class E/category 6 cabling should not be installed to support 10GBASE T. As a result, the cabling options for new installations that meet the 10GBASE-T standards for carrying data up to 100 meters are only found in the class EA/CAT 6A, class F/CAT 7, or class FA/CAT 7A.

Regarding data centers that are newly built, ISO, along with other standards organizations, have determined that CAT 6A should be the minimum grade. The task force overseeing IEEE 802.3 40GBASE-T have drafted the baseline objectives for the future 40 Gb/s standard, which is well beyond the capabilities of CAT 6A.

Cabling of a higher category traditionally matches and surpasses the electrical and mechanical standards of what preceded it. In addition, it is backwards compatible. Although TIA calls for cabling systems to perform at CAT 6A minimum, it will not be adopting CAT 7 or 7A as determined by ISO/IEC. TIA is naming its next class of cabling, Category 8, to differentiate it from ISO/IEC standards for CAT 7 and CAT 7A.

Interestingly, the proposed performance for CAT 8 will not be meeting or exceeding CAT 7A standards for up to 1 GHz. For example, regarding parameters for internal crosstalk, CAT 7A is superior to CAT 8 by more than 20 decibels.

Category 5e Cabling Becoming Obsolete

4 Apr 2017

cable,Data Cabling ,Cat5e, Cat6/6a CablingIt is inevitable that applications requiring speeds greater than 100 Mbps and 1000 Mbps will increase. The growing use of wireless devices, high resolution images, HD video streaming, surveillance, and multimedia are straining the capacity of Category 5e infrastructure, and there will come a point when it will be unable to cope.

Although it is capable of handling 1000 Mbps speeds at 100 MHz, the upgrading of Category 5e cabling will be necessary in the near future in order to support new applications and emerging technologies that will be deployed by businesses that are bandwidth intensive.

Category 5e Inadequate in Near Future

Cabling will be migrating from being behind walls to above ceilings, where it can end at a wireless access point (WAP). Much more cabling will be needed to serve an increasing utilization of WAPs for numerous users.

The advent and growth of new Wave 2 WiFi devices, which transmit at data at ranges of 1 Gbps up to perhaps 7 Gbps, will require faster Ethernet links for the connection of these WAPs. Installing Category 6A cabling may be the only effective solution for companies. The need for average speeds greater than 1G is increasing, perhaps to 10G. Category 5e is incapable of carrying speeds of 10 Gbps speeds over a required distance of 100 meters.

An emerging technology using balanced twisted-pair cabling, HDBaseT is used to transmit uncompressed HD video, audio, Ethernet, control, and power over 100 meters. Category 5e will be unable to support it, while Category 6A cabling is capable.

4-cable pair PoE, the next power over Ethernet standard, provides power more efficiently. However, the gauge of cable must grow in order for the reduction of resistance and permit higher power delivery. Consequently, 4-pair PoE has superior performance on Category 6A 23 AWG than Category 5e 24 AWG.

Cabling Standards Recommend Category 6A

For certain organizations, such as educational institutions, commercial buildings, data centers, and healthcare facilities, new installations require or recommend at least Category 6 cabling. Even though Category 6A may require greater capital expenditure than Category 5e cabling, costs will be decreased in the long term. A company’s network will be future proofed and will be capable of supporting new applications and emerging technologies.

All About Cat6a Cable

11 Feb 2013

Cat6a Cabling in AtlantaIt was once thought that copper cabling would never support speeds above 1 Gig, but Augmented Category 6, or Cat6a - has proven that wrong. Copper still lives and copper cabling may still be around at 40 Gig.

There has been much debate about which is the better option for supporting 10 Gig: Cat6a Unshielded Twisted Pair (UTP)  or Cat6a Shielded Twisted Pair (STP)?  Both solutions have their uses, and some key information can help installers make informed decisions.

Standards and Alien Crosstalk

The IEEE released the 802.3an 10GBASE-T standard in June of 2006, which specifies 10Gbs data transmission over four-pair copper cabling. The Telecommunications Industry Association (TIA) then began work on transmission performance specifications for the cabling. They published TIA Standard 568-B.2-10: Transmission Performance Specifications for 4-Pair 100 Ohm Augmented Category 6 Cabling in February 2008.

The new Cat6a standard extends the frequency of Cat6a cables to 500 MHz with specifications for a new performance parameter called Alien Crosstalk (ANEXT). Cat6a cables are fully backward compatible with all previous categories, including Cat6 and 5e. NEXT is crosstalk that occurs between adjacent cables and connecting hardware. The higher frequency signals of Cat6a makes ANEXT the limiting noise source for Cat6 and Cat5e systems.

Cat6a UTP vs. STP

Due to its ease of installation and familiarity among installers, Cat 6A UTP is today’s cabling of choice as it can support future bandwidth needs and 10Gb/s performance. In addition, the shield n the STP cable helps prevents electromagnetic and radiofrequency interference (EMI/RFI) on twisted pairs, helping eliminate the effects of noise from sources like machinery, generators, or medical imaging equipment, making STP systems the  choice for industrial and healthcare facilities.

As most residential systems are not faced with EMI/RFI challenges, so UTP is still the recommended cabling type for home installations.
