Product Description
850nm MM Visual Fault Tester

We use DFB-LD as the emitting component of the visual fault tester HK-4M 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. 

1) MQW LD optical source 
2) Operating mode: CW and MOD 
3) FC, SC, ST general interface, can use FC-LC adapter 
4) Long inspection distance 
5) Steady power output 
6) Nano technology, multi-ply ESD protection 
7) Sturdy and durable shell 
8) Pen pattern design, convenient for use and carry 
1) Locate the fiber failure, such as fracture and bend 
2) Failure inspection in OTDR blind zone 
3) Fiber recognition from head face to end face 
4) Mechanical transition point optimization 
1) Telecom, CATV project 
2) PDS construction and maintenance 
3) Optical component manufacture and research 
4) Other fiber project
