Datacom Textron MicrOTDR Optical Fault Locator
The MicrOTDR Optical Fault Locator is a rugged, lightweight, hand-held test instrument for locating faults in multimode and singlemode optical fiber cable. MicrOTDR utilizes patent pending OTDR (Optical Time Domain Reflectometer) technology to make fault location measurements to distances up to 20 kilometers, with pinpoint accuracy. The unit operates at the industry standard wavelength of 1310 nm, and displays the distance to a fault in meters or feet.

Datacom Textron MicrOTDR

The MicrOTDR is designed to measure the distance to fiber events along fiber cables in optical fiber systems. Useful applications for the MicrOTDR include testing: Wide Area Networks (WANs), telecommunication spans of up to 20 kilometers, Fiber-to-the-Curb applications, installation of multimode and singlemode fiber cabling, and military systems. The unit is an excellent tool for locating faulty connectors, damaged components, bad splices and breaks in singlemode and multimode cable sections. It is also much easier to use than an OTDR for checking reels of fiber optic cable for length and defects.

The MicrOTDR has been designed with the technician in mind with many easy to use features. It has a large LCD display for viewing ease, and can be used on multimode or singlemode cables. Its’ easy “one button” operation is used for activating the unit’s measure function, and the Index of Refraction (IOR) setting can be field selected with the use of a single button. The MicrOTDR is designed to record up to seven events, displaying the distance to each event.

The MicrOTDR is powered by four AA Alkaline batteries that can provide greater than 13,000 operations. An advanced power supply circuit ensures maximum battery life. Sensing circuitry alerts the operator of “low battery” conditions. The auto power-off circuit turns the unit off 5 minutes after the last reading to preserve battery power.
