Production Overview
6318 series Optical Fiber Visual fault locator adopts 650nm welength semiconductor laser ,inject visible light (red light) into optical fiber ,then we can find the damage position by searching for light-leaking position .This production is suitable to test bare optical fiber, fiber jumper or near-end fault point of other optical fiber and cable which can leak red light, and high loss area caused by slight curve. 
Working together with OTDR to remedy the defect of OTDR near-end blind area. It can quickly detect the jumper, damaged connector and cut-off position at the OTDR testing blind area .Besides ,it can be used to compare the cores of multi-core cable/ribbon fibers .

Main Characteristics  This production is small size ,easy to carry ,hold with one hand, very suitable to cooperate with OTDR and optical fiber fusion splicer  at the constructing/ maintaining process .
 Inject visible light (red light) into optical fiber , then we can find the damage position by looking for light-leaking position by eyes , much more convenient and accurate .
 Working with OTDR . It can fast detect the jumper, damaged connector and cut-off position in the OTDR testing blind area .
 This product equips FC,SC,ST three type of interface ,users can choose different optical fiber port type .

Typical Use
Use the 6318 series Optical Fiber Visual fault locator to locate optical fiber jumper fault position as follows .



Connect fiber jumper under test with a break in the fiber to the Optical Fiber Visual fault locator and turn it on, it's default mode is Continuous light mode , visible red laser light is injected into the jumper ,we can see the fault position has light leaking , switch the locator to Modulation Light Mode ,the fault position has red light sparkling and find the damaged position more specific .
