End Lit Glass Fibre Optic Harnesses

The only UK manufacturer of raw fibre for fibre optic harnesses

Our range of glass fibre harnesses are made up of tails which contain many fine glass fibres sheathed in a black coloured low smoke Megolon material.

The ends are finished with crimp terminations for small diameters and with brass or stainless steel ferrules for larger diameters. Ferrules allow end fittings to be attached to the fibre tails.

Larger diameters are available on request with soft silicone at the ends of the tails for use when articulated fittings are used in a tight space for the fibre bend radius.

Standard ferrule options are shown in the ordering codes table below, however, other options are available including 1/4" smooth, M7 and 8mm smooth. Ferrules are supplied in brass as standard or in stainless steel for use outdoors or in damp areas.

Features & Specifications

UFO glass fibre optic harnesses offer unparalleled light output, very long life and extraordinary colour characteristics.

Benefits of UFO end lit glass fibre include:

  • Resistance to high temperatures which offers the greatest possible light output without heat filters
  • UV resistant common end
  • Flexible multi-fibre construction
  • High packing density which ensures compatibility with tightly focussed light sources
  • High quality glass fibres offering exceptional transmission and colour characteristics
  • Factory terminated common ends for superior quality, performance and longevity

Flexible sheathing

Megolon S540 is a thermoplastic, halogen free cable sheathing compound which exhibits an excellent level of fire retardancy. This product is specifically aimed at designs of cables requiring a good degree of flexibility and the ability to meet the more stringent fire test specifications.
