Bare fiber adapters provide a simple and effective way to use un-terminated fibers with commercial receptacles. Its use only needs to simply strip and cleave your fiber and insert into the bare fiber adapter. Broken fibers are easily removed with piano wire, allowing hundreds of insertions. They are recommended for power meter hook-ups, temporary system repairs or wherever a quick fiber connection is required.
Standard adapters accommodate 81 micron, 125 micron or 140 micron cladding fibers with a typical insertion loss of less than 1 dB.

Operation Instructions:
Notes: When using alcohol and acetone, please carefully follow all the safe, healthy and disposal information given on the container label, and on any material safety data sheets.
1. If you are using the bare fiber adapter with un-cabled fiber, proceed to step 2. If you are using cabled fibers, strip at least 3 inched of the cable’s outer jacket and cut away the exposed strength members(usually Kevlar fiber near the stripped edge).
2.Strip a sufficient amount of the buffer to allow for fiber cleaving. The length of buffet stripped from the fiber will depend on the type of cleaving tool used.(Usually 1” to 2” is adequate.)
3.Cleave the fiber, leaving approximately “1/2 to 5/8” of exposed fiber.(See the illustration above).
4.Clean the exposed cladding with acetone and/or isopropyl alcohol(reagent grade).
5.Depress the spring-loaded buffer clamping mechanism and insert the cleaved fiber into the acceptance hole. Push the fiber through until the cleaved fiber end is flush with the ceramic ferrule end face. At this point release the buffer clamping mechanism and hold the fiber in place. Inspect the end face with an eye loop and if necessary, adjust the fiber until it is flush.
6.Clean the surface of the ceramic ferrule with a lint-free, alcohol dampened cloth and blow dry with compressed air.
7.The fiber is now ready for use. Insert the adapter into the optical test equipment’s coupler.
