Optical fiber trouble detector straight is small and light. It can export the visible red laser of
human eye, and high-efficiently enter single module and multi module optical fiber. Leading
red laser into optical fiber by optical fiber connector, can be used as contrast among cores in
the optical fiber. It can check optical fiber trouble point which OTDR cant find ( characteristic
of the breakpoint ,the beginning and the end) and area of high loss caused by bending. For
example, optic fiber jumper, tail fine, terminal box of optic fiber core line or bare optical fiber ,etc..



Main feature:
● Visual Fault Locator is used for locating broken point in fibers .
● Visual Fault Locator is equipped with a 650-nm visible laser diode can be operated in continuous or pulse modes for clear noticeable results .
