The feasibility of wavelength division multiplexing 800, 1300 and 1500 nm channels over an 8 km long, installed, 1300 nm optimised single-mode fibre loop has been demonstrated. A 780 nm CD-laser and Si APD receiver were used to transmit data at 150 Mbit/s on one of the channels. A 0.25 metre long, 800 nm optimised SM fibre section was used at the receiver to filter the LP/sub 11/ mode propagating in 1300 nm optimised SM fibre at 800 nm. The mode filter significantly reduced intermodal distortion, thus allowing high-speed 800 nm transmission over the loop. Edge-emitting, 1300 and 1500 nm LEDs were used to transmit 140 and 90 Mbit/s data, respectively.<>
