Thank you for purchasing the Wilcom Model FR2Optical Fault Locator. The Wilcom FR2 Optical FaultLocator is a rugged, light-weight, hand-held, easy-to-use "one button" operation unit for multimode andsinglemode applications. This instrument uses patentpending OTDR (Optical Time Domain Reflectometer)technology to make measurements. The FR2 is designedto pinpoint faults in an optical fiber cable, that can beover 10 kilometers distant, with amazing accuracy. Theunit operates at the industry standard wavelength of1310 nm, and can display the distance to a fault in metersor feet.

The FR2 is designed to measure the distance to fiberevents along fiber cables in optical fiber systems .Usefulapplications for the FR2 include testing: Wide AreaNetworks (WANs), telecommunication spans of up to10 kilometers, Fiber-to-the-Curb applications, installa-tion of single mode fiber cabling, and military systems.The unit is an excellent tool for locating faulty connec-tors, damaged components, bad splices and breaks insinglemode and multimode cable sections.

The FR2 has been designed with the technician in mindwith many easy to use features. It has a large LCDdisplay for viewing ease, and can be used on multimodeor singlemode cables. Its' easy "one button" operation isused for activating the unit's measure function, and theIndex of Refraction (IOR) setting can be field selectedwith the use of a single button. The FR2 is designed torecord up to seven multiple events, and display thedistance to the event(s).

The unit can be equipped with either an ST™, FC, or SCconnector that is optimized for multimode or singlemode cables. Adapter cables are available to launch intodifferent style connectors.

The FR2 is powered by four AA Alkaline batteries thatcan provide greater than 13,000 operations. An ad-vanced power supply circuit ensures maximum batterylife, and a display annunciator alerts the operator of a"low battery" condition. The auto power off circuit turnsthe unit off 5 minutes after the last reading to preservebattery power.

The FR2 has been designed using the latest state-of-the-art patent pending technology to ensure perfor-mance and reliability.
