SV10F Visual Fault Locator

SV10F visual fault locator has special laser driver circuit design, to make sure the laser output power remains a constant power level as long as in an available battery voltage. It is an efficient and low cost basic fiber test tool, it provides a visible way to find fiber faults and identify fibers in an optical network during and after installation, including finding the breakpoint, poor connections, bending or cracking in fiber optic cables; finding the faults of OTDR dead zone; End-to-end visual fiber identification.
