Optical Time-Domain Reflectometer Performs Visible Fault Location

News Release from: GAO FiberOptics Inc
22 October 2010

GAO Fiber Optics has announced the release of its handheld optical time-domain reflectometer (OTDR) with TFT LCD, which is designed for the manufacture, construction and maintenance of fiber optic communication systems. It locates faults of optical fiber and measures its physical characteristics including length, transmission loss and splice loss and performs visible fault location (VFL). This portable reflectometer is especially useful for Fiber-to-the-x (FTTx) network testing.

This optical time-domain reflectometer, model 6416, features a short event dead zone of 1.6m, a high resolution of 0.25m, 65535 sampling points and a long operating time of more than 10 hours on a single charge. It offers a maximum distance range of 256km and a memory capacity of 800 traces. This rugged OTDR offers optional wavelengths including 1310, 1550, 1625 and 1490nm at an accuracy of ±20nm. It provides dual USB interfaces supporting both USB stick and direct cable download to a computer via ActiveSync. In addition, the compact OTDR supports Bellcore GR196 file format for file management.
