Temporary test fiber optic coupler
Tests can be performed quickly and easily without termination using ST bare fiber adapters. The ferrule of the bare fiber adapter and the optical fiber through hole are free of epoxy glue and any medium, which is easy to insert, pull out and repeat multiple uses of bare fiber. And it has lower. The TJ-03 provide a temporary fiber splice for fiber and cable connections to test equipment such as OTDRs. The TJ-03 uses a precision ceramic V-groove to align up to 12 fibers. The fibers are prepared for joining by using standard mass fusion fiber preparation tools (fiber holders, hot jacket. An optical coupler is a passive device that can split or combine signals in optical fibers. The TS126 Mechanical Fiber-to-Fiber Splice is compatible with fibers that have cladding sizes between Ø125 µm and Ø140 µm. -
