End Lit Glass Fiber Harnesses

Our range of glass fiber harnesses are made up of tails which contain many fine glass fibers sheathed in a black colored low smoke 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 fiber tails.

Due to the very fine nature of the glass fibers, they can be mixed up in the common end connector (a technique known as randomising) which allows for a more even light output between individual 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 fiber 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.
