Usage:using the fiber connector imputs the red light into the fiber,using for the fiber comparision of many fiber cable.It can detect the fiber fault that OTDR can not and the high wastage junction causing by the bending.Like the core wire of fiber patch vord,pig tail,Fiber junction box.Or Bare fiber and so on.Fiber identification distance is up to 5km.It is the instruments which each maintenance technician must be equipped.

Functions and features:
Solar power storage type,generally light after 3 hours work for 8 hours straight.Find a breakpoint,bending,connectors fault break in;OTDR shadow of the failure to find; end to end fiber identification;use generic adapter.No need to change connectors.

Use:
Cleaning the fiber interconnect devices before the test and connect the optical fiber plug with the detector's output interface connector,push test switch,then output of visible red light detector,the user can determine the fault by the red light inside the fiber or connector breakpoint and slightly curved.
