Red light generated by the HiLite will escape from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors.

The HiLite is an excellent compliment to an OTDR because it can pinpoint faults inside the OTDR’s dead-zone. Other applications include end-to-end continuity checks, identifying connectors in patch panels and identifying fibers during splicing operations

Also available is the Noyes HiLite Converter which converts the 2.5mm to a 1.25mm for use with LC and MU connectors.
