1X2 (2x2) Fused Coupler
Description
Pusmai 1X2 (2x2) fused optical splitter is two or more optical fibers bound together, and then melt-stretching in the tapering machine, real-time monitoring split ratio change, when splitting ratio meet the requirements ,ended molten stretching, one end of a retention optical fibers (cut the rest) as an input end and the other end is used as multiple channel output. ,Sharetop Coupler compliance with Telcordia GR1209 and Telcordia GR1221
