Abstract
1500257 Optical fibre coupler THOMSON CSF 25 Nov 1976 [28 Nov 1975] 49293/76 Heading G2J Separate fibres 10 are bundled together adjacent a planer surface of a rod 2 this latter having at least two mutually orthogonal planer surfaces 8, 9 and covered with a reflecting surface so that a signal in any fibre is reflected back into all fibres.
