Panel VI: Building the Next Generation 3.2T Transceiver

Thursday, 10 March 12:30 – 14:00
Theater I

Session Description:

As transceiver data rates approach 1.6T and 3.2T, industry is in discussion on the transceiver form factors between pluggable and CPO. In this session, we invite panelists from all levels of the transceiver, from component to module vendors and to hyperscale cloud providers to present their approaches. By the conclusion of this panel presentation and Q&A, the audience will have a better understanding of the industry trend and ecosystem for 3.2T inside datacenter transceivers.
