The Telecommunications Industry Association (TIA) TR-42.11 Engineering Committee on Optical Systems on Sept. 21 issued a call for interest for document TIA-526.7-A, initially titled, "Measurement of Optical Power Loss of Installed Single-Mode Fiber Cable Plant, Adoption of IEC 61280-4-2 edition 2: Fibre-Optic Communications Subsystem Test Procedures – Part 4-2: Installed Cable Plant – Single-Mode Attenuation and Optical Return Loss Measurement."
TR-42.11 is developing guidelines in the area defined by the following scope:
“This standard is applicable to the measurement of attenuation and optical return loss of installed optical fiber cable plant containing single-mode fiber. The principles of this standard may be applied to cable plants containing branching devices (splitters) and at specific wavelength ranges in situations where passive wavelength selective components are deployed, such as WDMs, CWDM and DWDM devices. This standard is not intended to apply to cable plant that includes active devices such as fiber amplifiers or dynamic channel equalizers."
Stakeholders in the project, according to TIA, may include, but are not limited to: fiber and cabling suppliers; structured cabling bodies such as TIA-TR-42; test equipment providers; installers and users of single-mode cabling.
TIA said it is actively seeking participation in the project from the user and general interest communities. For more information about TR-42 and how to participate in standards development with TIA, contact Cheryl Thibideau at [email protected].
