FC Bare Fiber Adapter Overview

The FC Bare Fiber Adapter is a reusable fiber testing accessory designed to provide a temporary connection between prepared bare optical fiber and an FC/UPC test interface.

It allows technicians to connect bare fiber directly to an OTDR, optical power meter, optical light source, or compatible fiber test instrument without installing a permanent connector. The epoxy-free design makes the fiber easy to insert, remove, and test repeatedly during fiber inspection, troubleshooting, production testing, and laboratory measurement.

The adapter supports standard 125μm single mode and multimode fibers. Its ceramic alignment core helps maintain stable fiber positioning and low optical loss when the fiber is correctly stripped, cleaned, cleaved, and inserted.

With insertion loss of ≤0.2dB and a compact reusable structure, the adapter is suitable for field technicians, laboratories, fiber production facilities, and optical equipment maintenance. It provides a fast connection method for unterminated fiber without fusion splicing or permanent connector installation.
