Abstract

A multi-function fibre-optic communication system has been constructed for carrying radar information from a radar head end to a remote display area. High bandwidth video signals have been carried on FM subcarriers on a single fibre per channel basis. The radar video channels were a 20MHz analogue signal, a 10MHz analogue signal, and a 10MHz digital signal composite with a synchronising pulse. The aerial turning data was digitised and transmitted serially via a dedicated fibre with considerable capacity for additional information. Duplex speech and a TV video signal were transmitted over a single fibre using FDM and WDM. All the signals have been carried over a 3Km length of multimode optical cable using 1300nm led sources to reduce material dispersion. The WDM duplex link also used an 850nm led in the return direction.
