Product Desciption

Visual Fault Locator BOB-VFL650-2S

This type VFL is specially designed for field personnel who need an efficient and economical tool for fiber tracing, fiber routing and continuity checking in optical networks. It finds breakpoints, poor connections, bending or cracking in fiber optic cables; and it can find faults in an OTDR dead zone and is used for end-to-end visual fiber identification.
Applications

Maintenance in telecom, CATV
Test Lab of optical fibers
Fiber routing and continuity checking in optical networks
Other fiber optic measurements

Features

2.5mm universal connector,for 1.25mm connectors,

FC(male)-LC(Female) adaptor also can be provided on request

Operates either in CW or Pulsed mode with constant

output power

Low battery warning
Long battery life (up to 60 hours)
Drop-resistant and dust-proof design of laser head
Laser case ground design prevents ESD damage
Portable and rugged
Easy to use

Product Description
The Visual Fault Locator launches 650nm visible laser light into the fiber.
When the light encounters a break or sharp bend, it scatters, and the scattered
light can be observed emerging from the cable. The Visual Fault Locator can
locates breaks in short patchcords, which an OTDR cannot detect due to their
operating dead zone. A fault locator is also much cheaper than an OTDR.
However, they are not recommended for using with dark-colored or armored
cables.
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. Often a connector may appears to be perfect. But
inside the connector ferrule itself, poor gluing or dirty may create a microbend
in the fiber. This microbend will produce excess insertion losses or return losses,
and may result in premature failure of the connector. As the visual light launches
through the fiber, it emerges from the connector in question, one can readily see
the distortion as a series of rings superimposed on a normal output. Bending or
twisting the fiber may affect the overall intensity pattern, but not the ring pattern
itself.
