An optical-fiber identifier also referred to as a live fiber detector or optical-fiber detector, is a non-intrusive tool that detects optical transmissions, or any type of lack, in an optical fiber. For installing and maintaining fiber links fiber identifier is a valuable asset and it needs to be included in every technician`s toolkit.
As the instrument is very easy to use, the technicians may get into trouble when they assume that the measurement is equally simple and can be accomplished to published specifications with little room for interpretation. This is not the case. The engineering that is done behind an optical-fiber identifier is complex and exacting. The specifications given can hinder a technician`s analysis of the readings that the identifier has provided.
The optical-fiber identifier appears to be a simple device but it is technically sophisticated. On a fiber, the technician clamps the device and it then receives an indication of traffic direction, presence (or absence) of modulation, and, on some units, a core power reading. Without any time-consuming equipment setups, the technician can quickly assess the viability of the fiber system. This can be done because the optical light source identifier can make these measurements quite rapidly.
An optical-fiber identifier is such an invaluable aid with which an installer can perform the following functions:
• With the use of tone generators, it traces signals
• Through splices and connectors, it verifies continuity
• Identifies signal direction (transmit or receive)
• Identify live or dark fibers
On a fiber system, this device provides the technician with important real-time operational data and when compared to more elaborate precision measurements it saves time and money.
Basically, by a process known as macro bending the identifier samples the light, where the fiber is bent around a precise radius that allows light to leak through the cladding and protective coverings into detectors. This small amount of light is then amplified by optical power meter, it is then processed with the help of an identifier and indicated on the front panel of the device. To minimize insertion loss the goal is to sample as small a signal as possible.
