Columbus-III was a transatlantic telecommunications cable connecting Europe to North America.
History and details
editColumbus-III entered service since December 1999[1][2][3] and it's owned by over 30 carriers. Supported by 90 repeaters, it's 9833 km long.
After a 2009 upgrade, the capacity of the system between the United States and Portugal was increased from the original design capacity of 8 x 2.5 Gbit/s to 160 Gbit/s initially. The upgraded system could accommodate up to 320 Gbit/s with potential to go even further beyond.[1][2][3]
The cable was decommissioned in December 2020. [4]
