In this paper, we analyze benefits of photonic integration-based sliceable transponders (sliceable photonics) compared to discrete optics transponder-based solutions (CFP/CFP2—C form-factor pluggable) in metro and long-haul networks. The metrics considered for comparison include the number of transponders, bandwidth use and power utilization. We assumed an OTN-based network with QPSK and 16QAM modulation schemes for both the scenarios. We observed that sliceable photonics is much more advantageous than discrete transponder optics in both metro and long-haul networks. We also compared the effect of modulation schemes on the efficiency of the network by comparing QPSK and 16QAM in discrete transponder optics and show that 16QAM in discrete transponder optics makes the network more inefficient.
