The Telecommunications Industry Association (TIA) TR-42.13 Engineering Committee on Passive Optical Devices and Fiber Optic Metrology has issued a call for interest for document TIA-455-171-B initially titled TIA-455-171-B: (Attenuation by Substitution Measurement for Short Length Multimode Graded Index and Single-Mode Optical Fiber Cable Assemblies). TR-42.13 is developing guidelines which describe the various methods available to measure the attenuation of optical components.

The stakeholders may include, but are not limited to manufacturers and users of fiber optics cables.

TIA is actively seeking participation in these projects from the user and general interest communities.

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).
