Passive optical networks (PONs) are the emerging solution for access networks since PONs provide high bandwidth. TDM ((time-division multiplexing) PON cannot support sufficient bandwidth for new broadband services such as UHD (ultra high-definition) IP TV, and VOD (video on demand). The solution is TWDM PON which is a mixture of WDM (wavelength-division multiplexing) and TDM. This paper proposes a new MAC (media access control) protocol for TWDM PON.
