Visual Fault Finder
Item# Model 52
Cercis Model 52 Series Visual Fault Finders are full-feature hand-held instruments enabling visual location of fiber breaks, faulty splices or defective connectors within splice trays and patch panels, or during component manufacturing and assembly. The visible laser light source glows brightly at the point of fiber breakage or severe bend.

It can be used to troubleshoot faults within OTDR dead zones, optimize mechanical or fusion splices, verify connector end-face polish, trace fibers end-to-end, and make loss measurements on POF, PCS or glass fibers. In bright or low light situations, the flashing mode increases visibility of the signal.
The optical port can be either FC-style or can have interchangeable adaptors—FC, ST, SC or 2.5 mm universal styles. Operation is simple via two keys: ON/OFF and MOD.

Available wavelengths are 635, 650 or 670 nm. Power output is rated at 1 mW (0 dBm) at all three wavelengths. Available with fixed FC connector, or with interchangeable adaptors: FC, ST, SC & 2.5mm universal.
