WDM

Telecom Italia (TIM), in partnership with Nokia, has achieved a wavelength speed of 550Gb/s for data transmission over a long-distance backbone network.

M-net and Nokia, have completed their first field trial of probabilistically shaped wavelengths using Nokia Photonic Service Engine 3 (PSE 3) super coherent technology.

The market for disaggregated WDM systems is growing, according to a recent report by market information firm, Dell'Oro Group.

The Optical Transport Quarterly Report covers manufacturers' revenue, average selling prices, unit shipments (by speed including 40Gb/s, 100Gb/s, 200 Gb/s, and 400 Gb/s).  It tracks DWDM long haul terrestrial, WDM metro, multiservice multiplexers (SONET/SDH), optical switch, optical packet platforms, and data centre interconnect (metro and long haul).
