Abstract: An optical fiber connector comprises a first fiber one end of which is in abutment with one end of a second optical fiber, the first and second fibers having substantially the same outside diameter and the second fiber having the same core diameter but a higher numerical aperture than the first. A mirror is arranged to focus light transmitted between the end of the second fiber and an optical transducer. The mirror defines an opening through which the first fiber extends.

Abstract: A wired broadcasting system is provided in which a signal path between a central station and at least some of a plurality of subscribers includes an optical fibre extending between an electro-optical transducer and a photo-sensitive detector. The optical fibre may extend over the whole length of the transmission path between the central station and each of the plurality of subscribers, or the optical fibre may extend between the central station and a distribution point from which signals may be conveyed to a group of subscribers over conductive paths, or an optical fibre may be arranged to extend between each of the plurality of subscribers and a programme selector located at a programme exchange.
