FAULT FINDER Specifications Light Source — 635-nm red laser diode and monitor, with multi-quantum well structure Central Wavelength — Nominal: 635 nm; Range (typical): 630 nm to 640 nm Spectral Width — < 2 nm Peak Power Output* — Into SMF-28 fiber, CW or MOD output mode: 1.0 mW (0 dBm) maximum, 316 µW (-5 dBm) minimum Maximum Emitted Power —... - Page 5 FAULT FINDER Introduction The Fault Finder is a pocket-sized instrument for finding problems in fiber cabling. It uses a stabilized, high-output 635-nm laser diode that runs up to 24 hours in continuous mode, or 48 hours in blink mode, from two AA alkaline batteries. The Fault Finder can clearly locate breaks and bending losses in optical fibers up to 3 km in length.

FAULT FINDER Battery Installation/Replacement The Fault Finder is shipped without the batteries installed. The two AA-size alkaline batteries shipped with the instrument must be installed before use. Do not use non-alkaline or rechargeable batteries in the instrument. NOTE If the LED indicator appears dim during operation, it is time to replace the batteries in the unit. -
Page 7: Operation
FAULT FINDER Operation Controls and Indicators “Quick connect” output port Rotary switch End cap Optional snap-on LED indicator connector adapter Dust cap Using the 2.5-mm “Quick Connect” Output Port 1. Insert the ferrule of a fiber optic connector into the “quick connect” output port, ensuring that it seats completely. - Page 8 FAULT FINDER NOTE Standard snap-on connector adapters cannot be used on the Fault Finder, as they are larger in diameter. WARNING! Do not look directly into the output port when the instrument is ON. Never use a viewing instrument, such as a magnifier or microscope, to view the free end of any optical fiber connected to the Fault Finder.
- Page 9 FAULT FINDER The Fault Finder can also be used to check the condition of ceramic ferrules. A fiber break inside, or past, the ferrule will make it glow, as shown above. If the entire connector glows, it is definitely bad. A glowing ferrule can also indicate a bad endface polish.
- Page 10 FAULT FINDER Cleaning Cleaning the Output Port Cleaning all connectors before coupling them to the Fault Finder ensures proper maintenance of the output port and laser lens. Always cover the output port with the dust cap when you’re not using the Fault Finder. If binding or stickiness is felt when inserting connectors into the output port, the ceramic sleeve should be cleaned.
