First Experimental Demonstration of Physical-Layer Network Coding in PAM4 System for Passive Optical Interconnects

We propose to implement physical-layer network coding (PLNC) in coupler-based passive optical interconnects. The PLNC over PAM4 system is for the first time experimentally validated, where simultaneous mutual communications can be kept within the same wavelength channel, doubling spectrum efficiency.
