Will Taiwan-listed and US-listed optical transceiver suppliers report 1.6T module volume shipments as their largest datacom revenue contributor in any quarter reported by 2027-12-31?

1.6T stays behind 800G through 2027

Optical circuit switching keeps large, sustained, structured AI traffic flows direct and optical for longer, reducing the repeated electrical switching and packet-processing layers that would otherwise pull demand toward higher-speed pluggable transceivers. This architecture favors sustained use of existing 800G deployments over a fast transition, so 1.6T module revenue stays below 800G through 2027. Yield or laser supply constraints could reinforce this by limiting how fast 1.6T volumes can ramp.
