Abstract :
Using a 1.3 μm wide-bandwidth surface-emitting LED, transmission experiments were performed with 50/125 μm multimode, graded-index fibre. Pulse shaping and equalisation were used in achieving a 10-9 bit-error rate at 1.0 Gbit/s over 3.0 km with a system margin of 1.1 dB. At 500 Mbit/s the margin increased to 7.0 dB. The 3.0 Gbit km/s data rate-distance product represents a new level of performance for a surface-emitting LED and multimode fibre.
