Data links that carry signals as light between chips, packages and racks, used where copper runs into distance, heat and bandwidth limits.
Cisco told the Open Compute Project summit that its 102.4-terabit Silicon One G300 is now shipping to customers at volume. Buyers can order against those dates. The optics module Cisco showed with Nvidia rests on Cisco's own bandwidth claims.

The Ascend 960 is dated 2027 and the 970 is dated 2028, but the only large order on the record is DeepSeek's 160,000 chips of the current generation. That fleet is forty pods of silicon Huawei ships today.

CScale emerged from stealth with $188 million, backed by Nvidia and Intel Capital, to build optical links for AI clusters spanning dozens of racks. Its pitch is that compute keeps running when a laser fails, though it has not said how.

The optical interconnect startup is now past a billion dollars in outside funding, with Nvidia, AMD and MediaTek on the cap table since March, and its chief executive says everything has to be qualified for volume production by the end of 2027.

Huawei used HUAWEI CONNECT 2026 to publish its own specification for a 4,096-chip cluster with a petabyte of shared memory, aimed at models approaching 10 trillion parameters.

Operators are betting light replaces copper between the chips inside a data centre. Whether it does turns on hall temperature and cable routing as much as on an optical cost curve that is still expensive.

KeyBanc's optical thesis for Marvell and Marvell's own revenue guidance both land near $30 billion, four years apart and measuring different things. The purchase price for the technology is already committed.
