635nm Visible Light Source

The KD Optics VLS-40 is an easy to use, hand-held, visible source used for testing fibre optic cable installations. It is especially useful when testing fibre optic cables close to the terminal equipment. The unit is pocket sized with a long battery life, making it ideal for local fault finding and continuity checking of fibres.

Wavelength.

The output wavelength is 635nm, which is approximately nine times brighter than other units operating at 670nm, which means a break or loss is much easier to see; the light will even pass through jacketed cables containing kevlar.
