Fiber optic detector LFD-250B

Breaking free of the limitations of traditional live fiber detectors Traditional live fiber detectors (LFDs) use thumb-activated fiber bending at a fixed angle to enable the detector to read the power leaking from the jacket. Since the bending is fixed and optimized for one wavelength and one fiber type, the bending often causes: Excessive loss Unreliable fiber detection (fiber activity is not detected) Unreliable tone/traffic detection Permanent damage to the fiber In addition to being unreliable, the fact that they can cause excessive loss is the main reason why traditional LFDs are considered dangerous and are not used on high-data-rate routes and in long-haul-network applications. EXFO’s LFD-250B Live Fiber Detector introduces step-motor-activated bending and makes fixed-angle bending—and the drawbacks stated above—a thing of the past.
