NF-904 Visual Fault Locator uses the DFB-LD as the emitting component . Driven by constrant current source , the indicator can emit stable red laser . The product can be used to inspect fiber failure when they connect with optical interface and be inserted into single mode or multi mode optical fiber . It is indispensable tool in fiber project constructing , fiber net-work maintaining , optical component manufacture and research .
• Find the breakage and winding of fiber optical cable .
• Examine the fault in OTDR dead zone .
• End to end fiber recognition ,
• The optimization of the machine connection point .
