OPTICAL FIBRE TERMINATION

摘要

A termination for an optical fibre comprises a planar support block which has an aperture therethrough for receiving and accurately locating an optical fibre end. The block is constructed out of a plurality of platelets, the aperture being provided by aligned, laser-drilled holes which are formed in each platelet. The holes, which are characteristically tapered, all taper in the same direction. They can therefore act as guides during insertion of a fibre end. Alternative arrangements are also described. The termination is for use wherever an optical fibre must be accurately located relative to another component. It finds particular application as a support for a rear-entry photodiode, as described.
