A time-division-multiplexing (TDM) system transceiver with 4-channel 10 Gb/s inter-faces to achieve 40 Gb/s non-return to zero (NRZ) transmission is presented. The front-end components are implemented in an indium phosphide double hetero-junction bipolar transistor (InP DHBT) technology. They include a 4:1 multiplexer with a voltage controlled oscillator and clock multiplication unit, modulator drivers for electro-absorption and differential lithium-niobate modulators, trans-impedance amplifier, limiting amplifier and 1:4 demultiplexer with clock and data recovery circuit. The transceiver was used to test optical transmission over a 2.26 km link with a 40 Gb/s, 2 31-1 pseudo-random bit sequence (PRBS) data. The transmitter achieves better than 12.9 dB extinction ratio, 1 ps added root mean square (RMS) jitter and 4 dBm output power. Without any optical amplification the receiver achieves -9.1 dBm back to back sensitivity at a bit error rate (BER) of 10 -12 and a high dynamic range of 12.5 dBm.
