Abstract

A 4km line-of-sight optical link, operating at 1.5 micrometers , has been established over central London. The link is being used to investigate the effects of atmospheric attenuation and turbulence on the transmission of high speed data. The power margin of the link has been increased to greater than 20dB by the use of an erbium fiber amplifier and a bootstrapped optical receiver. Results indicate that it is viable to transmit 155Mbit/s OOK NRZ data across the link in a variety of weather conditions with this margin.
