This Visual Fault Loctor (VFL) is specially designed for field workers who need an efficient and economical tool for fiber tracing, fiber routing and continuity checking in optical networks. The VFL can find break points, poor connection point, bending or cracking in fiber optic cables; and it can find faults located in an OTDR dead zone and also can be used for end-to-end visual fiber identification.
The VFL launches 650nm visible light into a fiber. When the light encounters a break or sharp bend, it scatters, and the scattered light can be observed emerging from the cable. More importantly, The VFL can locate break points in short patchcords, which an OTDR cannot detect due to their operating dead zone.
The Visual Fault Locator can be operated in either continuous wave mode (CW mode) or in pulsed mode. Pulsed mode aids in locating faults under high ambient light conditions and improve battery life. It also could be used in checking connector quality.
NOTE: Customers need to buy battery by themself, because battery is refused by most mail agent to carry. This VFL uses normal AAA battery, so customers can easily get them from their local market.
