CANTAT-2

{{Short description|Canadian transatlantic telephone cable}}

CANTAT-2 was the second Canadian transatlantic telephone cable,

in operation from 1974 to 1992.

It could carry 1,840 simultaneous telephone calls

between Beaver Harbour, Nova Scotia and England. The parties involved were Canadian Overseas Telecommunication Corporation (now Teleglobe) and the British General Post Office. The cable was rerouted to Sable Island and renamed SITIFOG 2000 for a period, and was eventually decommissioned.{{cite web |last=Glover |first=Bill |title=History of the Atlantic Cable & Undersea Communications — Atlantic Cables: 1856-2018 |publisher=History of the Atlantic Cable & Undersea Communications |date=5 March 2019 |url=https://atlantic-cable.com/Cables/CableTimeLine/atlantic.htm |access-date=2 February 2020}}

The work on the U.K. end of the cable involved an accident in which Pisces III, engaged in repeater burial of the newly laid cable on the shelf off Ireland, sank. The submersible sank in {{cvt|1575|ft|m|1|abbr=on}} of water and was recovered with the crew safe after 76 hours.{{cite journal |last=Pass |first=H. |title=The Sinking and Rescue of Pisces III |journal=The Seventh Undersea Medical Society Workshop — Medical Aspects of Small Submersible Operations 19—20 November 1974 |pages=II-11 |publisher=Undersea Medical Society |url=https://apps.dtic.mil/dtic/tr/fulltext/u2/a018474.pdf |archive-url=https://web.archive.org/web/20200202155409/https://apps.dtic.mil/dtic/tr/fulltext/u2/a018474.pdf |url-status=live |archive-date=February 2, 2020 |access-date=2 February 2020}}{{cite magazine |last=Scott |first=David |year=1974 |title= Way Out Machines Lay New High-Traffic Cable |journal=Popular Science |volume=204 |issue=1 |pages=82–85|publisher=Times Mirror Magazines |url=https://books.google.com/books?id=1X1hL2LFT0AC&pg=PA82 |access-date=2 February 2020}}
