Identifying the correct fiber in an active optical network is essential when performing maintenance, tracing connections, or preparing for network changes. 3S TELECOM offers optical fiber identifiers designed to help technicians identify signal direction, detect optical traffic, and measure relative optical power without disconnecting the fiber under test, subject to the instrument's operating conditions and supported fiber configuration.

Our fiber identifiers can help distinguish target fibers in fiber distribution frames, patch panels, and other network access points. Depending on the model, features may include audible signal indication, directional LEDs, modulation frequency recognition, and interchangeable adapters for different fiber diameters.

By helping technicians confirm fiber identity before disconnecting or rerouting a connection, a live fiber identifier can reduce the risk of service interruptions and incorrect fiber handling during network maintenance.
