Optical fiber identifiers are designed to non-invasively identify continuous-wave signals in fiber optic cables. They are low cost, hand-held tools that identify signals in single-mode fiber without interrupting service or damaging the fiber. Optical fiber identifiers eliminate the need to open the fiber at the splice point for identification, eliminating the probability of interrupting service. Suppliers are located around the world and adhere to a variety of quality standards for optical fibers and optical fiber indentifiers. For example, both the International Telecommunications Union (ITU) and the International Electrotechnical Commission (IEC) have incorporated reduced water-peak requirements into fiber and cable specifications.
Optical fiber indentifiers are used to test the type of signal being relayed or identify the specific type of optical fiber being used in cabling systems. They can also be used to detect the traffic speed of an operating link, or in a 2 kHz tone injected by a test source. There are three basic types of fiber optic cable: single mode, multimode, and plastic optical fiber (POF). Optical fiber indentifiers can detect various types of signals, including continuous wave, live optical transmission, and low frequency modulated tones at 270, 1000, and 2000 Hz. Some optical fiber identifiers can pick up other tones.
