The AFL OFI 200D Optical Fiber Identifier is a low-cost, high-tech approach to non-invasive fiber optic signal detection. Using a low-insertion loss, macro-detection technique, it discriminates signals without disrupting service or overstressing fiber...

The AFL Noyes OFI-400 Optical Fiber Identifier detects signals transmitted through single mode fiber without disrupting traffic. It features multiple tone signal detection (270 Hz, 330 Hz, 1 kHz or 2 kHz) and set reference. A unique...

The AFL Noyes OFI-400C Optical Fiber Identifier is for use with single mode fibers including 250µm & 900µm, but is specifically designed for 2mm & 3mm jacketed single mode fibers. It detects and measures core power levels of optical signals...

The AFL Noyes OFI-400HP Optical Fiber Identifier is used to identify fibers without disrupting service. High power fiber identifier will detect power signal levels +33 to -40 dBm (@1550nm, 3mm fiber). A build-in power meter is calibrated for 3mm...
