PAM4 Transmission Experiment and Scalability Simulations on Multi-wavelength Selective Crossbar Switch

We demonstrate a multi-wavelength selective crossbar switch with up to two wavelength switching capability per crosspoint. The switch has a mean path loss of 2.43 dB. We demonstrate an error free high speed PAM 4 transmission at 111.16 Gbps. We also report bounds on the port count of the switch.
