10-Gbit/s optical receiver using ICs with low-capacitance HBT technology
1992
Abstract A 10-Gbit/s optical receiver is developed using low-capacitance HBT IC technology. The HBT allows a cutoff frequency of 45 GHz and a maximum oscillation frequency of 70 GHz. The receiver contains an automatic gain-control amplifier IC with a gain of 16 dB, a bandwidth of 10.7 GHz, and a decision-circuit IC with an ambiguity of 66 mVp-p at a data rate of 10 Gbit/s. The sensitivity of this receiver is −26.5 dBm at a bit error rate of 10−9. Transmission over a 140-km fiber was achieved successfully.
