100 Gbps PAM4 Transmissions Over 50 km With 40 dB Power Budget for PON Using a High-Gain Quantum Dot SOA (Th2A.6)

Presenter: Lakshmi Narayanan Venkatasubramani, Dublin City University

We experimentally demonstrate a 106 Gbps PON downstream signal transmission using a high-gain InAs/InGaAs quantum dot-based SOA as a preamplifier. We achieved a record-high power budget of 40 dB considering an HD-LDPC BER limit of 1×10−2.
