1. Story
2. The first fibre-optic cable across an ocean was completed, from Tuckerton in New Jersey to a branching unit off Europe and on to Widemouth Bay in England and Penmarc'h in France. It carried 280 Mbit/s on two working fibre pairs — about 40,000 telephone circuits, against 36 on TAT-1 thirty-two years earlier — with electronic regenerators, since the optical amplifier had been demonstrated only the previous year.

20. Evidence
21. Supports the TAT-1 route (Gallanach Bay near Oban to Clarenville, Newfoundland), its 36 telephone circuits and its 25 September 1956 inauguration, and the TAT-8 route, its 280 Mbit/s on two working fibre pairs, its roughly 40,000 circuits and its entry into service on 14 December 1988. V55 verification basis: retrieved by search, not opened. One retrieved source gives 26 rather than 25 September 1956 for TAT-1 entering service, and this pack records that discrepancy instead of resolving it.
