A high-speed transmission over step-index plastic optical fibre (SI-POF) using a resonant cavity light emitting diode (RCLED) is described. The integrated optical receiver is realised in 0.6m BiCMOS technology with an integrated large-area Si photodiode. The design consists of a TIA, equaliser and post-amplifier stage followed by a 50Ω output driver. The integrated equaliser can be adapted via an external control voltage to different SI-POF lengths and RCLED limited bandwidths. A data rate of 250Mbit/s can be transmitted over a 50m-long SI-POF with a sensitivity of -22dBm at BER of 10 -9 and over a 100m-long SI-POF with a sensitivity of -24dBm at a BER of 10 -6.
