High sensitivity 40 Gbit/s preamplified SOA-PIN/TIA receiver module for high speed PON

We demonstrate a receiver module which associates a preamplified detector with a transimpedance amplifier for next generation PON network. The module achieved in NRZ a very high sensitivity of -23 dBm at 25 Gbit/s and -21 dBm at 40 Gbit/s.
