Bare Fiber Adapter User Guide

Step 1: Prepare Materials

Step 2: Strip 15-20mm of the optical fiber coating

Step 3: Wipe the bare fiber clean with industrial alcohol

Step 4: Press down the switch of the bare fiber adapter
(press down the clamp plate for square bare fiber adapters and press down the round button for round bare fiber adapters)

Step 5: Slowly push the bare fiber into the guide hole

Step 6: Use a pen-type fiber optic cutter to cut the excess bare fiber that exposes the ceramic end face.
(The operation is completed by cutting the bare fiber. After use, pull out the fiber and it can be reused)
