Demonstration of PAM4-OCDM system with electrical amplitude-level pre-tuning and post-equalization for data centers applications
Optics Express, 2019•opg.optica.org
A PAM4-OCDM system with optical multi-/demultiplexing and electrical pre-/post-processing
is proposed for short-reach applications. We experimentally demonstrate, for the first time, a
power-efficient 4 OC x 10 GSymbol/s PAM4-OCDM system. The four PSK-OCs are
simultaneously generated using a single light source and a passive multiport optical
encoder and received by a single optical decoder and cascaded DSP. The effectiveness of
the electrical-domain amplitude level pre-tuning and post-equalizer are demonstrated …

The four PSK-OCs are simultaneously generated using a single light source and a passive multiport optical encoder and received by a single optical decoder and cascaded DSP. The effectiveness of the electrical-domain amplitude level pre-tuning and post-equalizer are demonstrated, considering different values of shot and beat noises.
