Chromatic dispersion penalty by angular coupling between a resonant cavity light-emitting diode (RCLED) and a plastic optical fibre is presented. To evaluate the influence of the angular-dependent spectral characteristics of the RCLED on the chromatic dispersion penalty, the effective spectral linewidth of the RCLED was defined and the bit error rate performances for 500 Mbit/s by 50 m transmission were calculated. The calculated results were in good agreement with the experimental ones that showed the chromatic dispersion penalty of 1.2 dB at BER 10-12 in the angle of 26deg.
