Cable Landing Station is one important component of a submarine cable system which comprises of Wet Plant and Dry Plant.
The Dry Plant of a submarine cable system is a segment between the beach manhole and the cable landing station, comprises of land cable, power feeding equipment (PFE) and submarine line terminal equipment(SLTE), etc. The Wet Plant of a submarine cable system lies between the beach manholes, consists of submarine cable, repeater/gain equalizer, branching unit. A typical schematic of a submarine cable system is shown below.
The PFE and the SLTE of a submarine cable system are installed at the cable landing station. In some cases, the PFE is installed at a cable landing station nearby the cable landing site, while the SLTE may be installed in another cable landing station much faraway. For example, the terminal station at Hillsboro for the SLTE of the TPE cable system is about 150 mile away from the cable landing site at Nedonna Beach.
Multiple submarine cable systems may share the same cable landing stations. The submarine cable system is connected with the terrestrial network at the cable landing station, through the so called backhaul system.
The cable landing site is usually carefully chosen to be in areas:
Multiple types of submarine cables may be used in a submarine cable system, subject to depth of the seabed where the cable lies.
The double armored submarine cable is used at the shore-end, terminated at the beach manhole at the cable landing site, and is interconnected with much lighter land cable going onward to the cable landing station.
In most of the jurisdictions worldwide, the cable landing license is required to land a submarine cable.
There are now the following submarine cables landing in Mainland China:
Cables to the US:
Cables connecting Asia：
Cables to Africa and Europe：
The cables land at 8 submarine cable landing stations in China.
China Telecom owns three cable landing stations, including
China Unicom owns four cable landing stations, including:
China Mobile owns one cable landing stations:
There are now 15 submarine cables landing in 7 cable landing stations in Taiwan:
Global internet giants and operators have heavy investments in Taiwan.
Google has two hyperscale data centers in Taiwan, one in Changhua County which costs US$780 million and was completed in 2013, the other in Tainan Technology Industrial Park which will cost US$850 million, with a power supply of 10MW. So, Google builds two subsea cable connecting Taiwan and the US, FASTER and PLCN. Google also acquies huge capacity on other subsea cables connectign Taiwan.
Besides local operators including Chunghwa Telecom, Far EasTone Telecom (NCIC), etc., Telstra represents a key player on submarine cable business in Taiwan, its EAC-C2C network landing in 4 cable landing stations in Taiwan, and being HKA landing party in Taiwan.
Geographically, the east and south coast of Taiwan island is of significant importance for the submarine networks, and is also a high-risk region for the submarine networks due to the characteristics of the geology of Taiwan.
The east and south of Taiwan are a complex system of belts formed by, and part of the zone of, active collision between the North Luzon Through portion of the Luzon Volcanic Arc and South China, where accreted portions of the Luzon Arc and Luzon forearc form the eastern Coastal Range and parallel inland Longitudinal Valley of Taiwan respectively. This region is encountered frequent seismic faults which may caused serious harmful impact to the submarine networks. For example, the magnitude 7.0 Hengchun Earthquake in December 2006 resulted in 18 cable cuts in 8 submarine cable systems, atastrophically disrupted Internet services in Asia and Pan-Pacific regions.
Currently, there are 15 subsea cables (17 if Seacom and MENA are considered seperate cables) landing in 15 cable landing stations in 5 cities across India, in Mumbai, Chennai, Cochin, Tuticorin and Trivandrum.
BSNL plans to construct new cable landing stations in Digha, Cochin, and the Andaman & Nicobar Islands. IOX will construct a new cable landing station at Puducherry. Reliance Jio is planning for new cables and landing station.
To have a full picture about submarine cables landing in India, please read following articles by an Indian expert Mr. Suvesh Chattopadhyaya:
According to Mr. Suvesh Chattopadhyaya's contribution, here is a complete list of submarine cables landing in India:
Brunei Darussalam is shaping up as a bandwidth transit hub for the Bornean States of Sabah, Sarawak and Kalimantan. Terrestrial fibre optic cables connect these Bornean States to Brunei cable landing stations which then provide direct connectivity to 9 international destinations, namely Singapore, Hong Kong, Malaysia, Thailand, Vietnam, Philippines, Japan, China and USA.
The Authority for Info-communications Technology Industry (AITI) facilitates the deployment of telecommunication infrastructure and services, including submarine cables, in Brunei. An Infrastructure Provider for the Telecommunication Industry (InTi) is required to deploy a submarine cable system into Brunei.
As of January 2020, Brunei Darussalam is connected to 4 active submarine cable systems, with a potential bandwidth capacity of 10 Tbps. These 4 submarine cable systems are landed in two cable landing sites in Brunei, namely the Tungku landing site and the Telisai landing site.
There are currently two cable landing stations:
There are now four submarine cables connecting Brunei:
Riding on the strong growth in IP-based traffic, Brunei has successfully lighted up 10 Tbps of international capacity to fuel bandwidth demand.
Brunei’s geographical location with no history of natural disasters like typhoons and earthquakes, and substantially lower power costs, presented the sultanate with added advantages as a connectivity and transit hub for the underserved regions of Borneo Island and the BIMP-EAGA (Brunei Indonesia Malaysia Philippines East Asia Growth Area)
Brunei is connected Sabah and Sarawak of Malaysia and the West Kalimantan Province of Indonesia with terrestrial connectivity via the border crossing of Sungai Tujoh, and with commercial traffic of 1 Tbps.
To land or operate a submarine cable in the United States, submarine cable operators must obtain a cable landing license from the Federal Communications Commission (FCC). The FCC’s International Bureau, Telecommunications and Analysis Division (TAD) issues licenses to own and operate submarine cables and associated landing stations in the United States pursuant to the Commission’s authority under the Cable Landing License Act of 1921.
A cable landing license must be obtained prior to landing a submarine cable to connect:
Applications for cable landing licenses are subject to initial review for completeness of information and, upon acceptance for filing, public notice inviting comment. The FCC's rules provide for streamlined processing with action within 45 days of release of the public notice where the applicant can demonstrate eligibility for streamlining under the FCC's rules.
The FCC will undertake to act on applications that are ineligible for streamlining within 90 days of issuance of a public notice unless the application raises questions of extraordinary complexity.
To qualify for streamlining the Applicant must send complete copies of the application:
The State Department has authorized the Commission to act on applications when the FCC notices the State Department in writing of the filing of an application and the State Department does not object within 30 days of the notification.
The FCC also coordinates with other Executive Branch agencies applications where a foreign citizen or foreign-organized entity, including foreign government, would hold a 10 percent or greater direct or indirect equity or voting interest in the licensee.
In such senario, the Non-Streamlined Processing may be applied. The Non-Streamlined Processing involves an opaque and sometimes unending review process used by what's commonly known as Team Telecom (i.e., a working group of representatives from the Federal government entities charged with ensuring national security: the Departments of Homeland Security, Defense, Justice, State, Treasury, and Commerce, as well as USTR and the FBI), according to Commissioner of the FCC, Michael O'Rielly.
During the Non-Streamlined Processing, the FCC may grant the applicants an Special Temporary Authority (STA) to carry out certain engineering works and/or partial operation in the territory of the United States. STAs are granted with a fixed expiration date, usually six months, or for the term necessary to cover a special event, etc. STAs do not have grace periods and are valid only through their expiration date. The FCC may grant extensions of an STA for a period of 180 days, but the applicant must show that extraordinary circumstances warrant such an extension.
As of December 2019, there are 74 FCC licensed submarine cable systems (either operating or planning to enter service) and 9 new submarine cables pending for submarine cable landing license.
