On Submarine Cable Networks, Systems are categorized in accordance with their corresponding coverage, resepctively:


According to public information from the Environmental Protection Department of the Government of the Hong Kong Special Administration Region (the EPD HK SAR), the Environmental Impact Assessment (EIA) report for the Pacific Light Cable Network (PLCN) is published.

According to Huawei Marine, Tropic Science Co., Ltd., China-ASEAN Information Harbor Co., Ltd., China Construction Bank and Huawei Marine Networks signed an memorandum of understanding (MOU) for the PEACE submarine cable project at the 3rd Asia Pacific Submarine Networks Forum on October 17.  The PEACE undersea cable network will span approximately 6,800 km to connect South Asia (via Pakistan) and East Africa (via Djibouti and Kenya).

Crosslake Fibre announces today that it has begun its underwater marine survey for its Lake Ontario submarine fibre-optic cable project.  The marine survey is a critical aspect of development for the new 60km cable being developed by Crosslake Fibre across Lake Ontario.

Aqua Comms DAC (“Aqua Comms”), the operator of Ireland’s first dedicated subsea fibre-optic network interconnecting New York, Dublin and London, AEConnect subsea cable system, has been named a finalist by Capacity Magazine in the “Project of the Year – Subsea Networks” category of the 2017 Global Carrier Awards.  The nomination recognizes Aqua Comms for the innovation, vision and excellence demonstrated in its partnership with Epsilon to bring European route diversity and on-demand connectivity to the colocation campus of NJFX (New Jersey Fiber Exchange). 

Seaborn Networks ("Seaborn") and Aqua Comms DAC ("Aqua Comms") announced recently the formation of a strategic alliance to provide a new, next-generation subsea route between South America and Europe, directly interconnecting Seaborn's Seabras-1 subsea cable system with Aqua Comms' America-Europe Connect-1 (AEConnect) subsea cable network. Seaborn's Seabras-1 and Aqua Comms' AEConnect Subsea Cable Systems now interconnect to create newest route between São Paulo and London. The offering is available exclusively through Seaborn and Aqua Comms. 

Infinera and Seaborn Networks (Seaborn) announced the successful completion of a subsea field trial demonstrating the industry’s highest spectral efficiency on an ultra-long-haul subsea cable. The 8QAM trial demonstrated 4.5 bits per second per hertz on the Seabras-1 cable, owned and operated by Seaborn, with a distance of more than 10,500 kilometers (km), enabling up to 50 percent more capacity than systems without advanced coherent technologies such as Nyquist sub-carriers and SD-FEC gainsharing. This trial raises the bar for optical performance by delivering the industry’s highest spectral efficiency in a commercially shipping product.

According to Microsoft,  the construction of 160Tbps Marea cable system has been completed as of September 21, 2017. Marea cable system is planned to be operational in early 2018. Construction of Marea started in August 2016, from design through construction, Marea was completed in less than two years.

Seaborn Networks announced on September 8th that its Seabras-1 subsea cable system is ready for operations.  Seaborn’s Seabras-1 is a new 6-fiber pair, 72Tbps submarine cable system that is the first and only direct point-to-point system between São Paulo (Brazil) and New York (US).

Seabras-1 is owned jointly by Seaborn Networks and Partners Group (a global private markets investment manager with USD 66 billion in assets under management) on behalf of its clients. Seaborn operates and maintains Seabras-1 from its offices in the United States and Brazil, including Seaborn’s own dedicated network operations centers in New Jersey and Massachusetts.

Globe Telecom has launched the USD 250-million Southeast Asia-United States (SEA-US) submarine cable system, providing direct links between Davao City and the United States.

Hawaiian Telcom, a member of the SEA-US consortium, announced on Friday that the historic $250 million Southeast Asia – United States (SEA-US) undersea fiber cable system is complete and ready for commercial service. The SEA-US cable system connects Indonesia, the Philippines, Guam, Hawai‘i and California.


The first trans-Pacific submarine cable system, TPC-1 (Trans Pacific Cable 1), was put into servie on on June 19, 1964. It's a submarine coaxial cable linking Japan, Guam, Havaii and mainland U.S.A. via Hawaii, with a small capacity of only 128 telephone lines. After that, many transpacific submarine cable systems were built continuously.

Now, the in-service transpacifc submarine cable systems include AAG, China-US CN, Japan-US CN, Pacific Crossng 1, Southern Cross Cable Network, Telstra Endeavour, TGN Pacific, TPC-5, TPE, Unity, etc.  

Since the first transatlantic submarine cable system, TAT-1, went into service on 25 September 1956, there have been 26 submarine cable systems accross the Atlantic Ocean. Most of the transatlantic submarine cable systems have been retired of communications service.

Now, the in-service trans-Atlantic submarine cable systems include CANTAT-3, TAT-14, Apollo, Atlantic Crossing 1 (AC-1), Atlantic Crossing 2 (AC-2, also called Yellow), Columbus-III, FLAG Atlantic 1 (FA-1), Hibernia Atlantic, Tata TGN Atlantic.

And construction of new trans-Atlantic submarine cable systems, including Hibernia Atlantic's Project Express and Emerald Atlantis,  are underway and expexted to be ready for service in the end of 2012 or early 2013.
