The first transatlantic submarine cable system, TAT-1, went into service on 25 September 1956. From then on, there have been the TAT series of transatlantic submarine cable systems, until the latest one TAT-14.
The TAT-8 was the first transatlantic fiber-optic submarine cable, constructed in 1988, connecting the United States, the United Kingdom and France. The TAT-8 cable system contained two working fiber pairs and one fiber pair reserved as a spare. The signal on each optical fiber was modulated at 295.6 Mbit/s (carrying 20 Mbit/s of traffic).
Currently, most of the TAT series of submarine cable systems have been out of service, except for the TAT-14.

Apollo is a 13,000 transatlantic submarine cable system, consists of 2 segments: Apolo North of 6200km and Apollo South of about 7000km.
The Apollo cable system creates two fully diverse transatlantic paths. Apollo North connects the United Kingdom and the US, and Apollo South directly connects France and the US.
The Apollo cable system was ready for service in February 2003, with 4 fiber pairs and 3.2Tbps initial design capacity on both Apollo North and Apollo South, for a total of 6.4 Tbps trans-Atlantic capacity. In 2014, the Apollo cable system was upgraded to a system capacity of 25Tbps with Alcatel-Lucent’s 1620 Light Manager (LM) submarine line terminal equipment using coherent transmission at 100 Gbps. In 2015, it achieved the capacity of 8Tbps per fiber pair.
The Apollo cable network was built, owned and operated by Apollo Submarine Cable System Limited, a UK based company jointly owned by Cable & Wireless Worldwide and Alcatel-Lucent. It is now owned by Vodafone.
The Apollo cables land in New York and New Jersey in the US. In New York, the cable landing station is located on Parr Property, Brookhaven Technology Center, Shirley, New York (40º 50.5’ N and 72º 53’ W. In New Jersey, the cable landing station is located at Wall Township, Manasquan, New Jersey (40º 9.5' N and 74º 6.1’ W).
In the UK, the Apollo North cable lands at the Bude Cable Landing Station, seamless interconnection with EIG, Glo1 and other cable systems.
In France, the Apollo South cable lands at Lannion Cable Landing Station.
The AC-1 (Atlantic Crossing 1) is a 14,000 km trans-Atlantic submarine cable system linking the USA and three European countries, the U.K., the Netherlands and Germany.
Global Crossing announced to build the AC-1 submarine cable project in 1997. And the AC-1 cable system was ready for service in 1999.
The AC-1 cable system comprises four fiber self-healing Synchronous Digital Hierarchy (SDH) ring network connecting the United States with the United Kingdom and Germany, with an initial design system capacity of 40Gbps (8*2.5G DWDM, 2 fiber pairs).
The AC-1 cable lands at the following cable landing stations:
The AC-1 cable system was privately owned by Global Crossing. Following the acquisition of Global Crossing by Level3 in 2011 and the acquisition of Level3 by CenturyLink in 2017, the AC-1 is now wholly owned by CenturyLink, as well as AC-2/Yellow, Mid-Atlantic Crossing (MAC), Pan-America Crossing (PAC), South America Crossing (PAC), etc.
The Yellow cable system (also known as Atlantic Crossing 2, AC-2) is a 6,400 km trans-Atlantic submarine cable system linking the USA and the UK.
The AC-2 was put into service in September 2000, with an initial design capacity of 320 Gbps on 4 fiber pairs.
In May 1999, Level3 decided to lay the Yellow transatlantic cable system, with 4 fiber pairs. At that time, demand was heavily outstripping supply. Other cables in place at the time included AC1, TAT 12/13. The construction and maintenance agreement for TAT14 had been signed, but the RFS date was not scheduled until late 2000. In 1999, long term indefeasible rights of use (IRU) for STM1/OC3 was priced at approximately $3 million and above. Coupled with this, the cost of ongoing operations and maintenance was in the region of $150,000 per year per STM1/OC3. The initial cost was relatively high for a single company, therefore the decision was taken to defray the large upfront project cost by entering into a strategic partnership.
Level3 signed a coconstruction agreement with Global Crossing which took two out of the four fiber pairs on the Yellow cable system. Operating in this environment meant Level 3 already recouped half the cost for Yellow before construction even began. Global Crossing marketed their two fiber pairs of the Yellow cable system as Atlantic Crossing 2, or AC-2. Global Crossing's private Atlantic Crossing 1 (AC-1) cable system was ready for service in 1999.
Level3 owned two fiber pairs and signed an IRU agreement on a fiber pair with Viatel. In this way, Level3 recovered approximately 70% of capital costs on the Yellow cable system before the system even entered service.
The AC-2/Yellow cable lands at Level3's cable landing station at Bellport, Long Island, NY, and Global Crossing's cable landing station at Bude, the UK.
After the acquisition of Global Crossing by Level3 and the followed acquistion of Level3 by Century Link, AC-1 and AC-2/Yellow are now wholly owned by Century Link.
