Fiber Identifier is a tool necessary for the maintenance of optical fibers, used to identify the optical fibers not yet damaged. It can detect anywhere in single-mode fiber and multiple-mode fiber.

During the maintenance, installation, wiring and restoration of optical fibers, we usually need identify and isolate a specific fiber without interrupting our business. By transmitting the signals with modulation sound (270Hz, 1 kHz, 2kHz) into one end of fiber 1310nm or 1550nm, the identifier can identify the fiber from the route. Besides, Fiber Identifier can indicate the traffic direction.
