Abstract: An optical fibre array termination is formed from two housing parts (14, 15) each of which has a flat surface (21) with a step (17, 18) on the surface, the height of the step corresponding to a fibre diameter. One part is placed over the other so that a rectangular aperture (11) is defined between the steps and a plurality of optical fibres are closely juxtaposed in the aperture. The parts are then secured together.

Abstract: A broadband digital transmission system enables high bit rate data stream to be transmitted over low bit rate telephone networks. A high bit rate stream of data from a source (2) is distributed by a distributor (4) into six separate streams to provide six low bit rate streams of data. A call unit (6) establishes six channel communication with a receiver (20) and the six data streams are fed in parallel along the six channels. A reassembler (34) receives the six low bit rate streams and reconstructs them to produce the original high bit rate stream of data.

Abstract: An optical filter is formed between the end face of an optical fibre (16) and a glass plate (32). The end face of the fibre and the face surface of the plate (32) are coated with a highly reflective coating. The fibre and plate define a Fabry-Perot cavity which transmits a particular wavelength or narrow range of wavelengths which can be detected by a photodetector (15).
