Are Coherent Transceivers About to Experience a Bandwidth Crunch?

Sunday, 24 March, 13:00 – 15:30

Room 6E

As future spectral efficiency growth prospects are limited, scaling to 1.6 Tb/s and beyond will be achieved almost entirely by increasing transceiver bandwidth. Single-wave line rates will hit the bandwidth ceiling if we cannot achieve a penalty-free transceiver bandwidth scaling of 2x every generation. When will this happen? If this does happen, what will transceivers look like? Multi-wave optics? Ever more power-constrained pluggables? Can we scale bandwidth indefinitely?
