Intra-Europe Submarine Cable Systems

The BlueMed cable system is developing by Telecom Italia Sparkle, linking Palermo with Genoa in Italy.

The BlueMed cable will cross the Tyrrhenian Sea connecting Sparkle’s Sicily Hub open data center in Palermo, which serves eighteen international cables, with Genoa’s new open landing station, directly connected to Milan’s rich digital ecosystem. BlueMed will also include multiple branches within the Tyrrhenian Sea and is set to support further extensions southbound of Sicily.

With a capacity up to 240 Tbps and about 1,000 km long, BlueMed will provide advanced connectivity between Middle East, Africa, Asia and the European mainland hubs with up to 50% latency reduction than existing terrestrial cables connecting Sicily with Milan.

The NO-UK Cable System is an open cable system providing a total of eight dark fibre pairs and up to 216 Tbps system capacity, connecting Stavanger in Norway and Newcastle in England. 

The NO-UK cable is building by NO-UK Com, the consortium comprising Altibox Carrier as the operator, Haugaland Kraft, BKK, Ryfylke IKS, Green Mountain, Polysys and Hatteland Group.

Through Altibox Carrier, the consortium can offer dark fibre or capacity backhaul routes to any major PoP in the Nordics or UK. 

The NO-UK will be a part of a larger European fibre network established by Altibox Carrier, Euroconnect-1, that will ensure robust and state-of-the-art digital infrastructure, connecting Norway to important digital hubs such as London, Brussels, Amsterdam and Hamburg. 

The NO-UK cable system is supplied by Xtera. The supply contract has come into force, and the NO-UK cable system will be ready for service by the end of Q4 2021.

The Skagen Fiber West is a 170km submarine cable connecting Norway (Larvik) and Denmark (Hirtshals). 

The Skagen Fiber cable system consists of 48 fiber pairs, provides over 1920 Tbps of system capacity and a designed round-trip delay (RTD) of approximately 1.7 ms between the Larvik cable landing stations in Norway and Hirtshals cable landing station in Denmark.

The Skagen Fiber cable system is building and owned by Lyse/Altibox (100%), to be ready by the end of Q3 2020.

In December 2019, Altibox acquired 100% of shares in Skagenfiber AS and the Skagen Fiber cable system between Norway and Denmark. Combined the Skagen Fiber cable system and the NO-UK cable system, Altibox Carrier is establishing a large fiber network across Europe, EUROCONNECT-1.

The COBRA Fiber Optic Cable is a 325km dark fiber G.654.D low loss cable between Eemshaven in the Netherlands and Endrup (Esbjerg) in Denmark via the German sector of the North Sea.

The COBRA Fiber Optic Cable can be connected to a subsea cable to the UK in Esbjerg, and a subsea cable to Norway in Bulbjerg.

The COBRA Fiber Optic Cable has been laid alongside the COBRAcable HVDC submarine electricity interconnector.

The COBRA Fiber Optic Cable has primarily been installed to control the HVDC electricity interconnector,  the remaining capacity is used for commercial purposes.

Both the COBRA Fiber Optic Cable and the COBRAcable HVDC submarine cable electricity interconnector are owned by TenneT TSO and Energinet. The Dutch company Relined Fiber Network is responsible for leasing the dark fiber capacity on the COBRA Fiber Optic Cable.

The COBRA cable forms a completely redundant and low latency route to Denmark. Running over the COBRA cable, the latency from Copenhagen to Amsterdam is less than 9ms (leading latency has been 11.5 ms), and latency from Copenhagen to London is 13.8 ms (leading latency has been 16.7 ms).

 

About the COBRAcable

The COBRAcable has been designed to facilitate the direct transport of wind energy generated at offshore wind farms, facilitating the transport of renewable energy and enhancing the security of supply.

COBRAcable is a 325km HVDC submarine cable electricity interconnector between Eemshaven in the Netherlands and Endrup in Denmark via the German sector of the North Sea.The COBRAcable submarine cable directly interconnects the high-voltage grids of the Netherland and Denmark. The COBRAcable has a capacity of 700 MW and has been commissioned since 2019.

The Celtic Norse Cable system is the first submarine fiber optic cable between Norway and Ireland, with further connectivity to the United States, enabling Norway to position itself as a prime entrant into the hyperscale and enterprise data center market.

The Celtic Norse cable route is approx. 2000km, lands at 

  • Oysanden, in Melhus municipality in Norway, just south of the city of Trondheim, onwards terrestrial connections going south to Oslo-and mainland Europe, as well as spur cables linking Northern Norway, and
  • Killala Bay, County Mayo in Ireland, where the trans-Atlantic AEC-1 cable lands.

The Celtic Norse Consortium comprises Celtic Norse AS, Vodafone Iceland and Aqua Comms.

Aqua Comms is the operations partner for Celtic Norse Cable system, as the landing party in Ireland and providing system NOC services to the consortium.

The Celtic Norse cable system is planned to be ready for service (RFS) in 2021.

 

NSC (North Sea Connect) is the first new-technology cable to connect Newcastle in the UK and Denmark, providing diversity between the UK and Northern Europe avoiding London.

The NSC cable system connects AEC System directly into Europe using the existing CeltixConnect-1 Irish Sea crossing as well as the CeltixConnect-2 northern Irish Sea crossing

There is a Branching Unit to facilitate future connections to Germany or the Netherlands.

The North Sea Connect cable system is owned and operated by Aqua Comms.

The CeltixConnect-2 (CC-2) is submarine cable connecting Dublin and Blackpool via the Irish Sea.

The CeltixConnect-2 (CC-2) connects with the existing CeltixConnect-1 and the North Wales Connect to form a fully diverse and reliable circuit between Dublin and Blackpool, with connectivity to New York and London through the AEConnect network, and a Branching Unit to facilitate connection to the Isle of Man.

The CeltixConnect-2 (CC-2) is a part of Aqua Comms' North Atlantic Loop network. CeltixConnect-2 (CC-2) and CeltixConnect-1 (CC-1) form a fully diverse ring between Dublin and Blackpool.

CeltixConnect-1 (CC-1) is a 131km long submarine cable system with 72 fibre pairs between Ireland and the U.K. 

CeltixConnect-1 (CC-1) provides the shortest, most secure crossing of the Irish Sea from Dublin to Anglesey in the north-west coast of Wales.

CeltixConnect-1 (CC-1) was ready for service in 2012 and is a part of Aqua Comms'North Atlantic Loop network.

CeltixConnect-1 (CC-1) and CeltixConnect-2 (CC-2) form a fully diverse ring between Dublin and Blackpool.
