Visual Fault Locator (VFL), Red Light Pen 10mW Fiber Optic Cable Tester Meter with 2.5mm Connector for Fiber Fault Finding, Up to 10KM

Product Information

The laser-powered VisiFault Visual Fault Locator is a cable continuity tester that locates fibers, verifies cable continuity and polarity. You can tap the PULSE/OFF/CW (continuous wave) button on the screen to change the modes of the VFL, or use the button as shown in the picture below. By pinpointing the exact location of fiber damage, technicians can diagnose, troubleshoot, and fix the problem efficiently.

Taking FS Pen-Type Visual Fault Locator, 1mW as example, it is small in size and easy to be carried away. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects. The working principle of fiber optic visual fault locator is as follows: The VFL fills the core of the optical fiber with light from the laser. coupled to single mode fibers and 2mW to free space (which means no fiber coupling, just the light output from the tester's connector adapter).Clean ST connector ferrule end face with a lint-free wipe (FWP-C) soaked with alcohol (reagent grade isopropyl alcohol, with a minimum 90% concentration). TheOptiFiber® Pro OTDR moduleand the CertiFiber Pro™ OLTS modules include a visual fault locator that sends a red light down the fiber. While breaks may be visible through the jacket of the fiber optic cable depending on jacket color, thickness, number of optical fibers in the cable, and amount of strength member. It can also locate the fault of OTDR dead zone and make fiber identification from one end to the other end. VisiFault can quickly illuminate fiber breaks, damaged connectors on patch cords, defective splices in splice trays, and tight fiber bends in and around equipment racks.

When the fiber fault locator is designed with adapter incompatible with your connector type, using additional adapters is necessary.Whether installing new fiber links or troubleshooting an existing network, the faster you can locate a problem, the faster you can fix it. When this happens, the most difficult element is detecting which connector contains the optical fiber break. Depending on the jacket color, thickness, number of optical fibers in the cable, and amount of strength member, breaks may be seen through the jacket of the fiber optic cable. You can diagnose and repair simple fiber link problems with Fluke Networks' VisiFault TM Visual Fault Locator (VFL). Connect the VisiFault to one end of a fiber then locate that fiber at the other end, even if it one of many fibers either in a cable or terminated in a rack.
