Pacific Light Cable Network (PLCN) connects Hong Kong, Taiwan, the Philippines and the US.

PLCN offers the first direct submarine cable connectivity between Hong Kong and Los Angeles, the US, spanning approxiamately 13000 km. PLCN offers the shortest RTD between Hong Kong and Los Angeles. 

PLCN is the first and currently the only submarine cable system in the world to deploy with C+L band optical technology.  C+L band technology had been technically feasible when PLCN project was luanched in the end of 2015. The deployment of C+L band almost doubles the per fiber pair capacity and the system capacity in PLCN. Later in 2018, the Space Division Multiplexing (SDM) technology was available and more popularily selected as an alternative solution to increase system capacity while decreasing cost per bit.

The PLCN cable system consists of 6 fiber pairs, with 240 channels of 100Gbps in a single fiber pair (100G * 240 WL), 24 Tbps per fiber pair and 144Tbps for the whole system.

The PLCN cable system is co-building by Google, Facebook and PLDC (Pacific Light Data Communication). SubCom supplies the PLCN system with its industry-leading and innovative C+L band solutions.

Google owns one fiber pair in PLCN, connecting Hong Kong and the US with a branch to Toucheng, Taiwan on this fiber pair. Google acts as the landing party in the US and Taiwan. In the US, Google lands the PLCN cable at Equinix LA4 data center where houses the PFE and SLTEs of the whole PLCN cable system in the US territory.

Facebook owns one fiber pair in PLCN, connecting Hong Kong and the US with two branches to the Philippines on this fiber pair, landing at Baler, Aurora and San Fernando, La Union respectively. The  Baler and San Fernando cable landing stations are owned by the Philippine state-owned firm Bases Conversion and Development Authority (BCDA).

PLDC owns four out of the six fiber pairs in PLCN, acts as the landing party in Hong Kong. PLDC lands the cable at Deep Water Bay CLS in Hong Kong and installs their SLTEs at TMH, Telecom House data center in downtown, Wanchai, Hong Kong.

Designed with Open Cable structure, each of Google, Facebook and PLDC can operate its own PLCN fiber pair(s) independently.

China-US CN (China-US Cable Network or CUCN) is the first submarine cable system with direct cable routes linking the U.S. and China, reaching several countries in the Asia-Pacific region. This trans-pacific subsea optical fiber cable system was planned in 1997 and put into service in early 2000, constructed by a consortium including AT&T, China Telecom, NTT, KT, CHT etc.. China-US CN subsea cable consists of four optical fiber pairs in its northern trans-pacific trunk between Chongming cable landing station and Bandon cable landing station, and southern trans-pacific trunk between Shantou cable landing station and San Lius Obispo cable landing station, as well as the western and eastern trunks linking Shantou- Chongming, and Bandon-San Lius Obispo respectively, with branches to Japan, Korea, Taiwan and Guam. China-US CN was designed with 8x2.488 Gbps (STM-16) SDH over DWDM, a total of 80 Gbps trans-pacific system capacity with SDH self-healing ring protection. China-US CN was the largest trans-pacific subsea cable system as of its commencement of service.

The Southern Cross Cable Network (SCCN) forms a protected ring network among 9 cable landing stations (two each in Australia, New Zealand, Hawaii and the US mainland, and one in Fiji) and an access point in San Jose, California. The Southern Cross Cable Network contains 3 fiber pairs between Sydney and Hawaii, and 4 fiber pairs between Hawaii and the US West Coast, with almost 30,500 km in length, including 28,900km of submarine cable and 1,600km of terrestrial cable.

The Ready for Service (RFS) for Phase A of the Southern Cross network - comprising all nine stations and all segments except Segment D (from Hawaii to California) - was achieved on 15 November 2000. Completion of the fully protected loop network (RFS Phase B) was achieved on 28 February 2001.

The Southern Cross Cable Network is invested, owned and operated by Southern Cross Cables Limited (SCCL,a Bermuda private limited company) which was owned indrectly by Spark NZ (50%), Singtel EInvestments (40%) and Verizon Business (10%). In 2018, Telstra acquired 25% stake in SCCN and substantial capacity on both the existing network and the new Southern Cross NEXT subsea cable. As a result, SCCL is owned by Spark NZ (38.12%), Singtel EInvestments (30.49%), Telstra (25%) and Verizon Business (6.4%).

The Southern Cross Cable Network was originally designed to working with 10 Gbps DWDM and deliver 120Gbps of fully protected capacity (240Gbps across the network). 

On July 30, 2013, Southern Cross announced the completion of upgrade with Ciena's 100G technology, increasing its lit capacity to 2.6Tbps and system capacity to 12Tbps.

The latest upgrades (Phase J) will increase total lit network capacity to approximately 12.8Tbps over the next few years. Following the introduction of the latest 100Gbps technology the current system potential is estimated at more than 22Tbps.

Japan-US CN (Japan-US Cable Network or JUSCN) is the first high capacity trans-pacific subsea cable system using DWDM technology of 10 Gbps per wavelength. Japan-US CN consists of four fiber pairs, each operating at 10 Gbps DWDM, with design capacity of 640 Gbit/s. Initially, Japan-US CN operated at 80 Gbit/s with two lit fiber pairs, expanding to 400 Gbps in mid 2001 by lighting the two remaining fiber pairs each with 16 wavelengths at 10 Gbps per wavelength, further upgrading to 1.28 Tbps in early 2008.

 

The Telstra Endeavour cable system is 100 per cent Telstra-owned submarine cable system between Sydney and Hawaii, the largest ever commissioned by an Australian company. The Telstra Endeavour provides an improvement in latency over existing submarine cable systems.

The Guam-Philippines Cable System (G-P Cable System) consists of two optical fiber pairs between the Batangas Cable Landing Station in the Philippines and the Tanguisson Cable Landing Station in Guam. The Guam-Philippines Cable System was ready for service in March 1999, with a design capacity of 40 Gbps (2x8x2.5 Gbps).

The America Samoa Hawaii Cable (ASH Cable) is the international fiber optic cable between American Samoa, Samoa and Hawaii and connects Samoa to the existing global telecommunications infrastructure networks.

The ASH Cable comprises of two cables installed between Samoa, American Samoa and Hawaii.

In addition, the Samoa-American Samoa Cable (SAS Cable) will provide inter-island communication, as well as enabling users in Samoa to access the ASH cable capacity and connect to the global networks.

While ASH Cable and SAS Cable are much smaller than the gargantuan systems across the North Pacific, they will provide more than 40 times the capacity currently in use in both island groups combined.

The ASH cable project is significantly different from the traditional submarine cable provisioning. The Samoan islands are in a fortunate position to re-utilize the former PACRIM East cable between Hawaii and Auckland that runs along the seabed, about 100 miles east of Pago Pago in the island of America Samoa.

The PACRIM East cable was the original fibre optic cable across the Pacific, laid in the 1990’s. It had large capacity then but by today’s standards its capacity is insufficient to effectively service the needs of New Zealand and Australia. As such, larger capacity cables – Southern Cross and Telstra Australia’s Sydney-Hawaii cables with capacities of Terabits – service their needs.

The project involves recovering the PACRIM East cable from the seabed south east of American Samoa, cutting it and laying it into American Samoa at Pago Pago. During the pick-up process, additional cable will be recovered for re-laying between Pago Pago and Apia, Samoa.

Major cost saving has been achieved in relaying the fibre cable as only a small section of the cable is being recovered and re-laid.

The ASH/SAS Cable consists of three cable landing stations, i.e., the Keawaula Cable Landing Station in Hawaii, the Pago Pago  Cable Landing Station in American Samoa, and the Apia Cable Landing Station in Samoa. The ASH/SAS Cable was ready for service on 28 May 2009.

The Honotua Cable System is a 5000 Km submarine communications cable system that connects several islands of French Polynesia via Tahiti to Hawaii, USA. The international portion of the Honotua cable contains a single fiber pair designed with 32x10 Gbps DWDM system, with initial lit capacity of 2x10 Gbps. The domestic system comprises of 2 fiber pairs designed with 8x10 Gbps each, with an initial lit capacity of 2x2.5 Gbps. It has cable landing points at: 

  • Vaitape,Bora Bora,French Polynesia
  • Uturoa,Raiatea, French Polynesia
  • Huahine, French Polynesia
  • Moorea, French Polynesia
  • Papenoo,Tahiti, French Polynesia
  • Spencer Beach, Kawaihae, Hawaii

The Honotua Cable stretches 4,650 kilometers (2,890 miles) between Kawaihae, Hawaii and Tahiti, French Polynesia.

The baptismal name bestowed to this Polynesian project, HONOTUA, perfectly reflects the philosophy that lies behind it. HONO means link in the Tahitian language. It is the link between the human beings, peoples, cultures and civilizations. TUA means the open sea, the high seas. But it is also the back, the backbone. Thus HONOTUA is the link that relates Polynesian to the rest of the world, the backbone on which all the information channels interconnect.

The Honotua Cable System is owned and operated by the government-owned OPT (Office des Postes et Télécommunications) of French Polynesia, supplied by ASN.

In 2008, OPT and the Hawaii-based Wavecom Solutions (then known as Pacific LightNet Inc., or PLNI) signed a Landing Party Agreement (LPA) which permits OPT to land Honotua at the Kawaihae Cable Landing Station located near Spencer Beach on the Big Island of Hawaii. In 2012, Hawaiian Telcom completed the acquisition of Wavecom Solutions.
