The MLS635 is a stable visible light source that can be used to visually test optical fibre cables, splices and
connectors for both multi-mode and single mode fibres. Any sharp bends and breaks in jacketed or bare fibres or
poorly mated connectors will allow the generated visible light to escape making the MLS635 ideal for identifying
faults in fibre optic jumper cables, distribution frames, patch panels and splice trays. It can also be used for end-
to-end continuity tests, connector identification in patch panels and fibre identification during splicing operations.
