OSFP-XD Takes the Stand | fibeReality
At OFC 2021, the announcement by Arista Networks of the OSFP-XD, with an implicit endorsement by Google, we characterized as a knockout blow, most notably as it related to CPO.
Conclusion
The good news for Arista is that Google appears to be somewhat optimistic about the prospects for OSFP-XD, as it is immensely interested in denser optical FFs. We perceive that the search engine giant really wants the benefit of pushing out CPO for a minimum of two generations of interconnects, while allowing for backward compatibility to its OSFPs. It was also made clear at OFC that Google is not a fan of SiPh, supposedly a key enabler of CPO.
