What does an Optical Fiber Identifier do?

An Optical Fiber Identifier can be used to detect the existence of a signal on optical fibers. OFIs are attached to a fiber, where they create a safe macro-bend and enable a minor quantity of light to getaway. Units utilise this light to identify the existence of a busy network, test tones or CW signals and specify the direction of the signal.
