Visual fault tester(HK-C4)

We use DFB-LD as the emitting component of the visual fault tester HK-C4 Visual fault tester series red laser indicator. Which can test four pcs patch cord at one time.,Independently control for four channel.Driven by constant current source, the indicator can emit stable red laser. The visual fault tester can be used to inspect fiber failure when they connect with optical interface and be inserted into single mode or multi mode optical fiber. Visual fault tester is indispensable tool in fiber project constructing, fiber net-work maintaining, optical component manufacture and research.
