CanaLink cable system is a 1835km submarine cable connecting the Canary Islands to Rota, Spain's mainland.

CanaLink cable system is now 100% own by Canarias Submarine Link, SLU (CanaLink), the operation company owned by IT3 (Instituto Tecnológico de Telecomunicaciones de Tenerife, which is majority owned by Cabildo de Tenerife and devoted to the development of ICT sectors in the island). 

CanaLink was a joint venture equilly owned by IT3 and IslaLink, established in 2010 for the construction of the CanaLink cable system, wholly owned by IT3 since 2013.

The CanaLink cable system consists of several sub-systems:

1. Tenerife – Rota, with a branch to Gran Canaria-East
2. Tenerife – La Palma
3. Tenerife – Gran Canaria West
4. Tenerife – Peninsula protection (by means of a third-party cable)
5. Rota – Asilah branch (called Loukkos: a system belonging to Maroc Telecom)

Furthermore, the system incorporates several terrestrial transmission networks:

• In the peninsula, the network connects the landing points to the CLSs of Rota and Conil, and, from there, to Seville and Jerez respectively
• In Tenerife, a dual route links the CLSs at Güimar and Granadilla and connects them to a metropolitan ring in Santa Cruz de Tenerife.
• In Gran Canaria, the landing points are connected to the CLSs of Tarahales (Gran Canaria-West) and el Goro (Gran Canaria-East). The terrestrial optical fiber network links them to las Palmas de Gran Canaria
• In the Island of La Palma, a terrestrial fiber pair connects the landing point to the Instituto de Astrofísica de Canarias

The CanaLink cable system was designed with an initial system capacity of 5.12 Tbps along the main segment from continental Spain (Rota) to Tenerife, ready for service in 2011 and supplied by Alcatel-Lucent Submarine Networks (ASN).
