The presence of a signal is sensed by a signal transducer around which an optical fibre is wrapped so that the length of the fibre is modulated by any signal present. A laser supplies coherent light to one end of the fibre and a homodyne detector is provided at the other end. Discontinuities at both ...

A telecommunication system has a laser-energized multimode optical fibre highway. Data is entered on to the highway by means of a series of modulators each operating at a different subcarrier frequency. At the far end of the highway demodulation is carried out be a quadrant photodetector which appli ...

A signal transmission system impresses phase-modulated signals on to a multimode optical fibre waveguide 1. In order to overcome the effects of fading caused by small random changes in the parameters of the fibre the signals from different modes are all combined to derive a resulting signal which is ...
