An FTTH (Fiber to the Home) fiber identifier is a device used in fiber optic technology to determine if an optical fiber is live and to identify the direction of the signal flow without disrupting the network. It is a non-intrusive tool that can detect the presence of signals and measure the signal strength in optical fibers. The fiber identifier is typically designed to work with various fiber types and can handle different wavelengths. It is used during network installation, maintenance, and troubleshooting to quickly identify active fibers and verify signal continuity, aiding in efficient and accurate fiber identification in FTTH networks.
