Paper Abstract

Since the culmination of early work on 140 Mbit/s optical systems, a number of experimental links have been installed. The first, a nine kilometre link between Stevenage and Hitchin just north of London, in 1977, was chosen to demonstrate the suitability of optical communications for trunk networks. In 1979 British Telecom awarded contracts for the first phase of proprietary optical line systems, (POLS 1) for installation in the UK network between 1980 and 1982. POLS 2 and POLS 3 awards included seventy 140 Mbit/s systems, mainly using multimode optical fibre cables.
