On May 15, FiberHome Communications announced that it has successfully developed and mass-produced a 13,824-core ultra-large core count optical cable, which will make its public debut at the Wuhan Optics Valley Expo.
This is the first time China’s optical cable has exceeded the 10,000-core level, perfectly adapting to ultra-large-scale AI data centers with clusters of over 100,000 GPUs.
An optical cable contains multiple fiber cores, each core acting like a lane for data transmission. This record-breaking 10,000-core cable means there are over 10,000 lanes running simultaneously within a single cable, greatly improving data transmission efficiency.
The 13,824-core ultra-large core count optical cable from FiberHome Communications has an outer diameter of only 40mm, matching the diameter of a traditional 6,912-core cable, roughly the size of a standard ping-pong ball. It uses a modular precision structural design, achieving a core density of 11 cores per millimeter. A single cable can replace 48 conventional 288-core cables with a diameter of 19mm, saving 90% of pipeline resources.
Against the backdrop of comprehensive AI + optical connectivity upgrades and high-speed interconnection of computing power, the successful development of this 10,000-core ultra-large core count optical cable not only breaks foreign technology monopolies and fills domestic technological gaps but also significantly improves wiring efficiency in computing centers and reduces maintenance costs.
