Product Description
Optical Fiber Visual Fault Locator (VFL) is specially designed for field personnel who need
an efficient and economical tool for fiber tracing, fiber routing and continuity checking in an
optical network during and after installation.
Its red laser shines through most yellow-jacketed fibers to help you pinpoint breaks,bends,
faulty connectors, splices and other causes of signal loss. The convenient VFL-25 locates
faults visually by creating a bright red glow at the exact location of the fault on singlemode
or multimode fibers.
Standards Compliance
. RoHS:Free of hazardous substances according to RoHS 2002/95/EG
. IEC 60825-1-2011:Safety of laser products - Part 1: Equipment classification and requirements
Features
. MQW LD optical source; . Operating mode: CW and MOD;
. FC,SC,ST general interface; . Long inspection distance;
. Steady power output; . Nano technology, multi-ply ESD protection;
. Sturdy and durable shell; . Pen pattern design, convenient for use and carry.
