Fiber Networks Innovations for AI at Scale
summary
Meta needs to escalate from ~864 to 100,000 fiber strands between nearby data centers, so teams design and dig mega duct banks with 20 ft deep, 9 ft wide trenches, large vaults and a tunnel under a highway, select a heavier 1728 cable developed with AFL, and adapt jetting from ~3,800 ft to as little as 1,800 ft. Cable placement averages 5–6 cables per day and totals about 2.1 million fiber kilometers across the cluster.
