figure shows a correlation between the introduction of first switching silicon
and early shipments of Ethernet optical transceivers with 2 km reach (popular
in datacenters.) The forecast for 400GbE is the solid green line. The dashed green
line shows what researchers consider a very unlikely scenario in which 400GbE shipments retrace early
shipments of 40GbE (with a 6 year delay).
Combined portfolio for ROADM line cards will include fixed- and flex-band 1xN WSS, tunable mux/demux, dual-chip pump lasers, passive components, arrayed-EDFAs, optical channel monitors and optical time domain reflectometers
