The Telecommunications Industry Association (TIA) TR-42.12 Engineering Committee on Optical Fibers and Cables has issued a call for interest for document TIA-492AAAE initially titled Detail Specification for 50-µm Core Diameter/125-µm Cladding Diameter Class 1a Graded-Index Multimode Optical Fibers with Laser-Optimized Bandwidth Characteristics Specified for Wavelength Division Multiplexing. This new TR-42.12 project will define a specification for multimode fiber with the necessary properties to support transmission of multiple wavelengths including and beyond 850 nm. The performance is intended to enable transmission of at least 28 Gbps per wavelength for a total transmission capacity of at least 100 Gbps per fiber to a distance of at least 100 m. Today, standard data rates exceeding 28 Gbps are delivered over multimode fibers using parallel transmission. Consequently multimode solutions have been proposed for 400G Ethernet that require 32 fibers.
The stakeholders may include, but are not limited to: installers and users of multimode cabling; applications standards bodies such as IEEE 802.3 (Ethernet) and INCITS T11 (Fibre Channel); equipment providers of switching, storage, server and computing gear; component providers of optical transceivers, integrated circuits, fiber and cabling; structured cabling standards bodies such as TIA TR-42 and ISO/IEC/JTC1/SC25/WG3; test equipment providers.
TIA is actively seeking participation in these projects from the user and general interest communities.
For more information about TR-42 and how to participate in standards development with TIA, contact Germaine Palangdao at email@example.com.
A major function of the Telecommunications Industry Association (TIA) is the writing and maintenance of voluntary industry standards and specifications. These activities are carried out by the volunteer members of TIA engineering committees. On the public engineering committee pages, users will find recent meeting reports, agendas and notices for upcoming meetings, as well as links to some of the most popular standards from each committee. TIA is accredited by the American National Standards Institute (ANSI). Visit
