Visible Light Sources


Quick Overview

VLS8 Visible Fault LocatorVisible Light Source for fibre fault detection

The VLS8 series visible laser source is the first tool to add to any fibre optic tool bag. Nothing can find a fibre fault that is close by better than a visible light source.  The VLS8, with its small size and long battery life, make this the ideal visible source to fault find patch cords, pigtails and connectors when an OTDR is unable to find a fault that is too close to the source.

The VLS8 is suitable for both singlemode and multimode fibres and can be operated with a continuous beam or flashing at 2Hz for improved detection at long range.
