Abstract

1521778 Mode coupling in optic fibres POST OFFICE 28 April 1977 [9 Feb 1976] 04979/76 Heading G2J An optic fibre 5, having a plastics sheath 6 is crimped by a device 7 (or a helical spring) to deform the fibre slightly. It is stated that thereby differing modes propagating in the fibre are coupled.
