Fiber Networks Innovations for AI at Scale
summary
Project delivers over 100,000 strands per path by jetting hundreds of cables instead of buying paths from carriers, using 148 864‑fiber cables in phase one and 76 1728‑fiber runs in phase two. Team selects AFL’s 864 and develops a 1728 fiber 16.4 mm cable to double capacity in the same conduit, jets cables with cascaded machines (up to seven per run, reduced spacing to ~1,800–2,500 ft), digs 9 ft by 20 ft trenches and 10x12 ft vaults, and lays 2.1M fiber‑km within 5 km.
