Common Ends for Fibre Optic Harnesses

The only UK manufacturer of raw fibre for fibre optic harnesses

The common end is used to bind all the fibre tails together in a single connection, which can then be plugged into a standard 30mm diameter fibre port on a light source.

Available in various diameters, common ends are different for glass and polymer fibre, with those for glass being larger. We also offer 12.5mm and 14mm mini common ends which are particularly useful in display cases where it may not be possible to drill a hole large enough to take a full size 30mm common end.

Adaptors are also available to allow multiple mini common ends to be plugged together into one light source.

We also offer our unique Ezefix range of common ends which allow for end-user termination of fibre optics. See the tab below for more information on these.

PMMA Common Ends

Shown below is a typical common end used for PMMA fibre.

common ends for pmma fibre harnesses

Common ends for glass fibre are manufactured from aluminium and anodised black, whereas the type used for PMMA fibre are raw aluminium. The 30mm diameter section provides a snug fit in any standard 30mm light source port.

Mini Common Ends & Adaptors

Mini Common Ends

Mini common ends are useful in situations, for example in museum display cases, where there is either not room, or it is not aesthetically pleasing to have a full size common end cutout.

Availalble in two sizes; 12.5mm and 14mm, mini common ends are generally fitted to light tubes, bars and wands, but can also be used in other situations.

Mini Common End Adaptors

We can provide adaptors which allow mini common ends to be inserted into a standard light source port connector.

Available to take one, two or three 12.5mm, or one or two 14mm mini common ends, they have an outside diameter of 30mm and are fitted with grub screws to secure the mini common ends in place.

The Ezefix System

The Ezefix termination system makes it quick and simple to terminate polymer optical fibre for lighting applications without the use of specialist equipment.

It consists of a range of port connectors for connection of the fibre to a light source and ferrule connectors to finish end lit fibre and allow attachment of end fittings.

While factory termination is always recommended for PMMA fibre and is necessary for glass fibre, this connector system will give adequate results where maximum light output or evenness are not required.
