Submarine Cable Systems

Connecting Continents and Communities

Communication forms the essence of societies. The advancement of our modern societies has been echoed in the growth of our communication systems. In the current times, communication is playing an even vital role by connecting continents and people all over the world. Today, submarine cable systems carry over 99% of intercontinental traffic, making them the invisible enabler of global connectivity.

Portfolio Overview

NEC entered into the submarine cable system business in 1968 and has since marked a presence globally. Today, we prepare to launch submarine terminal equipment operating at true 100G line rates – delivering ever-lower cost per Gbps.

Key Projects

1) KLI - The KLI (Kochi Lakshadweep Islands) cable system directly connects Kochi, a major port city in the state of Kerala with the eleven islands of Lakshadweep Islands (Agatti, Androth, Amini, Bangaram, Bitra, Chetlat, Kadmat, Kavaratti, Kiltan, Kalpeni and Minicoy) Islands with a cable length of 1868 kilometers.

Salient Features

  • The initial capacity of the cable system is 2x100 Gbps and the expandable capacity is 1600 Gbps per fiber pair.
  • Repeated and Repeaterless & IRPA Embedded cables were used for construction KLI Cable System.
  • This project will play a pivotal role in advancing 'Digital India' and the 'National Broadband Mission' by facilitating diverse e-governance programs in Lakshadweep.
  • The Project is set to strengthen E-Governance, Tourism, Education, Health, Commerce, and Industries, uplifting the islanders' living standards and fostering comprehensive social and economic growth.

2) CANI – The CANI (Chennai Andaman Nicobar Islands) cable system directly connects Chennai with the eight remote islands of Andaman and Nicobar Islands ( Port Blair, Little Andaman, Car Nicobar, Kamorta, Campbell Bay, Havelock, Long, and Ranghat Islands with a cable length of 2300 kilometers and a design capacity of 100GB/second.

Salient Features

  • The cable system provides the remote Andaman & Nicobar Islands with ample bandwidth for supporting voice and data connectivity that enable the implementation of e-Governance initiatives, such as the establishment of new enterprises and e-commerce facilities.
  • The system is expected to assist educational institutes in the sharing of knowledge and will play a significant role in driving the “Digital India" vision, a campaign launched by the Government of India to ensure that Government services are made available to citizens electronically.

3) Asia Direct Cable (ADC) – 9400 km cable connecting China, Japan, Philippines, Thailand, Vietnam, and Singapore.

Salient Features

  • The cable will feature multiple pairs of high-capacity optical fibers and is designed to carry more than 140 Tbps of traffic, enabling high-capacity transmission of data across the East and Southeast Asian regions.
  • The project will enable high bandwidth tech advancements in the regions such as 5G, Cloud, and Artificial Intelligence.

4) B2BE (Bay 2 Bay Express Cable System) – 16000 km spread submarine cable system connecting Singapore, Hong Kong, and the United States.

Salient Features

  • The project will enable high capacity transmission of data across the Pacific Ocean with a round trip latency of fewer than 130 milliseconds.
  • It will contribute to expanding communications networks between the Guangdong-Hong Kong-Macao Bay Area, San Francisco Bay Area, and Singapore.
  • Carry at least 18 TbS of capacity/cable.

5) SJC2(SouthEast Asia – 2 Japan )- Superior cable system spanning 10,500 km connecting Singapore, Thailand, Cambodia, Vietnam, Hong Kong, Taiwan, mainland China, Korea, and Japan.

Salient Features

  • The cable will feature up to eight fiber pairs of high capacity optical fiber with an initial design capacity of 144 Terabits per second, thereby supporting high bandwidth intensive applications including Internet of Things, robotics, and analytics, and artificial or virtual reality applications.
  • 18Tbps of capacity per fiber pair.

6) MIST – MIST features an 8100 km submarine cable system connecting the lands of Singapore, Malaysia, Myanmar, Thailand, and India, enhancing network connectivity and bandwidth.

Salient Features

  • Deliver a design capacity of more than 216 terabits per second (Tbps)
  • MIST will enhance and contribute to expanding communications networks from Asia, improving network redundancy, and delivering highly reliable communications. It will also expand onward connectivity options in the Bay of Bengal with its landing at Myanmar and Chennai
