First Demonstration of a 100 Gbit/s PAM-4 Linear Burst-Mode Transimpedance Amplifier for Upstream Flexible PON

We demonstrate operation of a linear burst-mode TIA integrated with a commercial lensed APD supporting 100-Gbit/s PAM-4 with OMA sensitivity of −15.8-dBm and 50-Gbit/s NRZ with OMA sensitivity of −23.7-dBm. Dynamic range exceeding 21.7-dB is achieved for NRZ and 15.4-dB for PAM-4 reception.
