Huawei Marine and Tele Greenland Join Hands to Deploy 100G Network


Huawei Marine joins hands with Tele Greenland for the deployment of a 100G network along the Greenlandic Westcoast. The new coalition will also upgrade the capacity of existing Greenland Connect fiber optic cable, which connects Greenland with Iceland/Europe and North America. Huawei says once the new project is completed, the submarine system would be the world’s first 100G submarine network in the northern hemisphere.

Greenland is located between the Arctic and Atlantic Oceans with 80% of the island covered by ice and snow year round. Huawei Marine will supply the Line Terminal Equipment for the Submarine system. Installation of the Line terminal equipment supplied by Huawei will be done in collaboration with Tele Greenland for the domestic submarine cable system Greenland Connect North. Greenland Connect North will connect Nuuk, Maniitsoq, Sisimiut, and Aasiaat. The new submarine cable system is designed to have a capacity of 100G to each town at the initial phase. In addition, Huawei Marine will supply and install Submarine Line Terminal Equipment for the existing Greenland Connect system, which connects Greenland, Iceland, and Canada. For this Greenland Connect System also the initial capacity will be 100G.

The supply for the new Greenland Connect North system will have a design capacity of 4.8T, while the design capacity for Greenland Connect will be increased from 1,92T to 12.8T between Greenland, Europe, and North America.

By deploying new generation OTN-based unified terrestrial and submarine transmission equipment, Huawei Marine will provide advanced 100G solutions for Tele Greenland to achieve flexible unified management of both the Greenland Connect North and Greenland Connect systems. The supply allows both systems to achieve a multi-granularity OTN cross-connection and flexible bandwidth allocation to minimize operating costs and maximize the return on investment.

In a press release published at Huawei website, the Chief Wholesale Officer Flemming Drechsel from Tele Greenland said: “The Greenland Connect system is Greenland’s vital communication line, and there is little margin for error in the implementation and operation of the new system. Over the course of the negotiation process with several well-esteemed system providers, the Huawei Marine team has won Tele Greenland’s full confidence, that Huawei Marine will provide the highly reliable 100G DWDM equipment needed to enable us to deliver and fulfill our commitments to our customers.”

Mao Shengjiang, Chief Operating Officer of Huawei Marine said: “It is a great honor to cooperate with Tele Greenland and to further gain recognition of Huawei Marine’s technology and delivery capability. It is not the first time for Huawei Marine to deploy a 100G network in the Arctic region, therefore I believe that our experienced team will meet the challenges and successfully deliver our products services to help our customers and expand their networks to these remote regions.”

Greenland Connect is a submarine communications fiber optic cable system that connects Canada, Greenland, and Iceland. The cable contains two optical pairs specified for 128*10 Gbit/s wavelength each. Initial lit capacity is 1*10 Gbit/s for each fiber pair, which will eventually be able to upgrade depending on the demand. Two additional 10 Gbit/s Wavelength was installed in the summer of 2010. The cable has cable landing points at four locations such as 1. Milton, Trinity Bay, Newfoundland and Labrador (Canada, 2. Nuuk (Greenland) 3. Qaqortoq (Greenland), 4. Landeyjarsandur (South Iceland).

At its endpoints, the cable is co-located with the “DANICE” cable in Iceland and the Eastlink (formerly Persona Communications) “Trans-Gulf” cable in Newfoundland. Together these cables interconnect the networks of major carriers in Europe and North America. TELE Greenland operates this cable as part of its 4,800 kilometers long fiber-optic network between Iceland and Greenland and between Greenland and Newfoundland and Labrador. Greenland Connect Cable was laid from Trinity Bay, Newfoundland to Greenland by the “Maersk Responder” supported by the “Blue Castor” during July to October 2008 and from Landeyjarsandur to Greenland by the “Ile de Sein” supported by the “Ile de Brehat” The Cable was put in operation on March 23, 2009, and instantly reduced ping times by approximately 500 ms. in Nuuk (Capital). The link between Milton and Nuuk failed on May 3, 2013.

The current Greenland Connect cable was already planned to install in 2016 as an additional cable from Nuuk to Aasiaat with landing points in Maniitsoq and Sisimiut. Reports say a further connection to Qasigiannguit and Ilulissat in the Disko Bay were planned but found impossible due to icebergs frequently grounding and thus blocking potential landing sites.
