Abstract :
The bandwidth limitations due to material and modal dispersion are calculated for long-wavelength LED systems using measured attenuation and group delay characteristics for fibres of two different types. The data presented allow the establishment of selection criteria for LEDs used in 140 Mbit/s systems.
