ECOC 2019 THE YEAR AHEAD ANALYSTS
450 percent in 2022, albeit from a low volume base.”
In Dell’Oro Group’s Optical Transport Five-Year Forecast report (www.delloro. com) published in July 2021, 400 Gbps wavelength shipments are projected to grow 70 percent in 2022 and comprise most of the newly added capacity in the year driven by its wide adoption. Also, in 2022, the use of 400 Gbps ZR (400ZR) in a QSFP-DD form factor is expected to considerably ramp, driven by its small size, low power consumption,
a 400 Gbps signal through a single mode fibre well over 2,000 km without ever being converting back to an electrical signal. Also, in 2021 to the benefit of 2022, 800 Gbps- capable line cards have become more widely available with the addition of two more suppliers. Now, 400 Gbps wavelengths can be used in longer spans, increasing its attractiveness, usability, and demand.
interoperability, and favourable economics. As a result of these low-power pluggable optics that can transmit 400 Gbps wavelengths up to 120 kilometres, the interest in IP-over-DWDM (IPoDWDM), which is a system architecture that incorporates DWDM optics in an Ethernet Switch or Router, is growing. Dell’Oro Group forecasts 400ZR shipments to grow
