More thanhalf of the data center switch ports shipped in 2024 will operate at data ratesof 100 Gbps or greater, predicts Dell?Oro Group in a new report. The high-speedport shipments will occur within the context of an overall market in 2024 ofmore than 60 million ports shipped, the marketresearch firm states in its new Ethernet Switch ? Data Center Five YearForecast Report.

While 100-Gbpsports have shipped for some time, Dell?Oro analysts expect deliveries of400-Gbps ports will begin to ramp by the end of this year and into early 2021.These 400-Gbps ports will be followed at some point during the forecast periodby 800-Gbps ports. Ports at 400 Gbps and greater will compose more than 25% ofshipments by 2024, Dell?Oro predicts.

?800 Gbps,400 Gbps, as well as new waves of 100 Gbps will be enabled by faster SerDestechnologies and higher -speed optics,? said Sameh Boujelbene, senior directorat Dell?Oro. ?Optics will continue to play a vital role in the data centerswitch market. The availability of high-volume, low-cost optics is crucial indriving any speed transition.

?Additionally,as network speed increases beyond 800 Gbps, pluggable optics will hit densityand power issues. Hence it will become imminent for the industry to adoptalternative options such as co-packaged optics (CPO). We expect such transition tobring major disruptions to the supply chain as it requires new business andserviceability models,? Boujelbene added.

The Ethernet Switch ? Data Center Five Year Forecast Reportdescribes market trends and includes tables covering manufacturers? revenue,port shipments, and average selling price forecasts for various technologies:Modular and Fixed by Port Speed; Fixed Managed and Unmanaged by Port Speed.Port speed demand assessed in the forecast include 1 Gbps, 10 Gbps, 25 Gbps, 40Gbps, 50 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps.
