Pen-Style Visual Fault Locator - A Straightforward Solution for Optical Networks

Toronto, Ontario Canada (PressExposure) November 30, 2011 -- GAO Fiber Optics ( has released this pen-style visual fault locator (VFL) which is a most economical and efficient test tool for quickly verifying continuity, checking the validity of patch cables before or after installation, testing and finding breaks in LANs, verifying short lengths of installed fiber, or looking for cracked fiber in splice cases, bad connectors, tight crimps in fiber cables, backbone breaks or anywhere light continuity needs checking.

This handheld visual fault locator, model C0280001, as a straightforward solution for finding breakpoints, poor connections, bends or cracks in fiber optic cables, detecting faults in an OTDR dead zone and performing end-to-end visual fiber identification. It operates at a central wavelength of 650 nm ±10 nm and offers CW and Pulse operating modes. Its universal connector interface provides fast operation with many connector styles without the need to change adapters. It is drop and dust resistant and has a laser case ground design which prevents ESD damage. This pen-style VFL complies with CE standards including EMC, EMI and ROHS. In addition, it features high portability and durability, easy of use, long battery life and low battery warning.

This pen-style visual fault locator (VFL) belongs to GAO's family of Visual Fault Locators. This line also includes Handheld Visible Laser Source which uses visible red light to indicate the location of fiber faults from a macro bend point, break, problem coupler or connector or a mechanical splice that is not well aligned, Rugged Handheld Visual Fault Locator which is able to examine all kinds of patch cords, ribbons or bunched pigtails in the installation and maintenance of fiber optic networks, and Optical Visual Fault Locator.
