SC/UPC Round Bare Fiber Adapter

SC/UPC Round Bare Fiber Adapter

The SC/UPC Round Bare Fiber Adapter is a high-precision optical interface designed for quick and reliable connection between an SC/UPC connector and a bare optical fiber. It allows direct insertion of stripped fibers without the need for epoxy, polishing, or fusion splicing — making it an ideal solution for temporary fiber connections, testing, and measurement applications.

Constructed with a nickel-plated round metal housing and a zirconia ceramic alignment sleeve, this adapter provides precise core alignment, low insertion loss, and excellent repeatability. Its round body design offers comfortable handling and stable placement during lab or field operations.

Widely used in fiber optic testing systems, laboratory research, production inspection, and temporary patching setups, the SC/UPC Round Bare Fiber Adapter ensures consistent optical performance and long-term durability.

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)
