The Telecommunications Industry Association TR-forty two Telecommunications Cabling Systems Engineering Committee accredited the TIA-942-B Data Center, Cabling Standard. The updated standard consists of several good-sized changes from the previous model to assist facts facilities in coping with contemporary and future needs. TIA represents the businesses that deliver high-tech communications networks and is a global leader in developing industry requirements throughout a range of ICT segments.

The TIA-942-B trendy is available from the TIA Standards Store via IHS. It changed into permitted for the booklet in the course of TIA’s June Committee meetings and posted on July 12.“We made a large update to ANSI/TIA-942-B which will preserve tempo with the speedy technology modifications inside the records center surroundings,” said Jonathan Jew, editor of TIA-942-B.


“With the exponential growth in the data center market, TIA-942 is considered one of our most vital standards,” stated Stephanie Bernard Law Montgomery, TIA Vice President, Technology & Standards. “Our TR-42.1 Engineering Committee added its sizable expertise to reviewing and updating this preferred. The resulting replace will assist network designers, architects, and statistics center owners and executives layout infrastructure as a way to aid both modern and future desires.”



The TIA-942-B standard includes the subsequent, amongst different, changes from the “A” revision:

Incorporates TIA-942-A Addendum 1, which addresses information center fabrics Adds 16- and 32-fiber MPO-style array connectors as an additional connector kind for termination of extra than 2 fibers. The 16- and 32-fiber connectors have been standardized whilst ANSI/TIA-604-18 changed into the post. Adds Category eight as an allowed type of balanced twisted-pair cable and adjustments the advice for Category 6A balanced twisted-pair cable to Category 6A or higher.

Adds OM5 (wideband multimode fiber) as an allowed fiber type. The TIA-492.AAAE popular specifies OM5 fiber, which is designed to aid quick-wave wavelength division multiplexing. Details approximately the TIA-942-B general and its effect on Data Center Design will be among the many topics addressed all through the Oct 17th workshop, “Optimizing Data Center Performance,” hosted at TIA in Arlington. This workshop is programmed for folks that design, construct and control present-day facts facilities. More records are available here.


TIA-942 is regularly used with TIA-606, the administration popular. In the most recent version of TIA-606-C, published June 2017, Annex D provides extra hints for cabling management helping far-flung powering, which includes cable bundle identifier scheme. This maximum recent version replaces Addendum 1 to ANSI/TIA-606-B with a connection with ANSI/TIA-5048, adapted from ISO/IEC 18598 Information generation Automated infrastructure control (AIM) structures — Requirements, statistics exchange, and programs. This is an important improvement because it lets in computerized infrastructure management systems from distinct manufacturers to work collectively.

TIA-942 is also commonly used along with BICSI-002, which addresses quality practices, rather than minimum requirements, to design and implement data centers. While BICSI-002 becomes not meant as a standalone standard, it covers many components of facts center layout, other than telecom problems, no longer addressed using TIA-942. It ought to be utilized by statistics middle owners, architects, engineers, occupants, and specialists to determine and fully recognize information center layout necessities.

TIA-942 turned into the primary well-known, advanced by a permitted standards organization, that mainly addressed physical information center infrastructure. It specifies the minimum requirements for telecommunications infrastructure of records centers and laptop rooms, together with single-tenant organization facts centers and multi-tenant Internet hosting statistics facilities. The topology laid out in standards is intended to be scalable to any length facts center.

As an ANSI-permitted well known-improvement business enterprise, TIA revises its requirements on a 5-yr cycle. During that 5-year period, requirements can be reaffirmed, revised, or withdrawn. The TIA-942-A well known was published in 2012; TIA began paintings on revising the same old in 2015.
