Talk:Transatlantic telephone cable
From Wikipedia, the free encyclopedia
A private competitor during the 1990s was Global Crossing.
This minor note somewhat understates the fact that (despite the fact that Global Crossing is in bankruptcy proceedings) that their AC-1 (Atlantic Crossing 1) cable is one of the major transatlantic cables today.

According to http://www.tat-14.com/ the current capacity for TAT-14 is 640Gbit/s.. Has it been upgraded after it was installed?
The listing of Transatlantic Telephone cables shows TAT-1, which was put into service in late 1956, as having 36 (voice) channels. This may be incorrect? My recollection is, that across the Atlantic from Shoal Harbour, near Clarenville Newfoundland to/from Oban Scotland TAT-1 had 24 channels. The Atlantic crossing was a two cable system; one East to West the other West to East using equipment supplied by the ATT (American Telephone and Telegrah) Long Lines Division. There were submarine repeaters across the Atlantic powered from both ends of the cable. Repeaters Approximately every 30 miles? From Newfoundland to North Sydney Nova Scotia, my recollection that a 36 channel system supplied by the British GPO (General Post Office) was used. The repeaters on this system were more closely spaced than across the Atlantic because of the wider bandwidth required by both directions of transmission on a single cable and because there were 12 more channels than across the Atlantic. I worked for a company that in 1956 rented some of those 12 'additional' channels to provide telephone circuits from St. John's Newfoundland to, initially, St. John New Brunswick and eventually to other Canadian cities. We started off with 2 circuits, which was rapidly increased, if I recall correctly to at least 8 by early 1957. That TAT-1 had 24 channels would appear to be confirmed by the fact that TAT-2, which apparently used identical/similar technology, which was installed a year or two later also had 24 channels.
[edit] Submarine communications cable
Submarine communications cable seems more appropriate title for the more modern fiber cables ? Regardless, I have just done SAFE (cable) and would love someone to do a nice table for the other cables than TAT*. Wizzy 08:29, Mar 1, 2005 (UTC)
