Titel
Experimental systems for future coherent optical TV distribution and bidirectional communication
Abstract
In section 1 the TV distribution system is described, with particular reference to frequency stabilisation, receiver sensitivity, and the use of a transversal twin-guided tunable laser (linewidth less than 12 MHz) for fast receiver tuning. Section 2 turns to the use of frequency division multiplexing in the context of the Coherent Optical Broadband Island project. Important aspects of this project are the stabilisation of the distributed lasers, the further development of tunable receivers, and the investigation of appropriate network topologies. The use of star couplers for the latter is discussed in some detail.
