First co-packaged optics switches set for next year

Ranovus says two of its lead customers will deploy co-packaged optics next year.

They will deploy 25.6-terabit Ethernet switch chips but these will be proof-of-concept designs rather than volume deployments.

Hamid ArabzadehThe deployments will be used to assess the software and gain experience with their maintenance including replacing optics if needed.

“I do think 2024 is going to be the volume year,” says Hamid Arabzadeh, CEO of Ranovus, who expects to announce the customers before the year-end.

Part 2: Odin technology

Ranovus has tested a chiplet that combines electronics and silicon photonics. Dubbed Odin 8, the monolithic design is targetting the co-packaged optics opportunity, enabling silicon chips to communicate optically.

The company is developing two such chiplets: the 800-gigabit Odin 8 and the higher-capacity Odin 32 that supports 3.2 terabits of traffic.

The first use of Odin 8 will be for 800-gigabit client-side modules. “We already have three lead customers for our 800-gigabit module business,” says Hamid Arabzadeh, CEO of Ranovus.

The 800-gigabit pluggable modules using the Odin 8 are expected to be generally available from late 2021.
