This time around, the effort aims to characterize the EF of both transmission light sources and measurement light sources.
The Telecommunications Industry Association (TIA) TR-42.12 Engineering Committee on Optical Fibers and Cables recently issued a call for interest for document TIA-455-203-A. The initial working title of the document is “Light Source Encircled Flux Measurement Method.”
When announcing the call for interest, the TIA explained, “This fiber-optic test procedure is intended to characterize the encircled flux of two types of light sources: 1) transmission light sources, which are usually coherent and substantially under-excite the mode volume of a multimode fiber, and 2) measurement light sources, which are incoherent and must excite most of the mode volume of a multimode fiber.”
TIA is actively seeking participation in this effort from stakeholders that likely include manufacturers, developers and users of telecommunications optical fiber. Interested parties can get more information by emailing [email protected].
