The Tonga Domestic Cable Extension (TDCE) submarine cable is a high-speed fiber-optic cable that connects the island nation of Tonga with Fiji and the rest of the world. The cable was laid in 2013 and is managed by Tonga Cable Limited.
The TDCE cable is approximately 827 kilometers long and has a design capacity of 240 Gbps. It connects Tonga to the Southern Cross Cable Network, which spans from Australia to the United States. This connection provides Tonga with high-speed internet access and improved telecommunications services, allowing for greater connectivity and economic development.
The TDCE cable also serves as a backup for Tonga's previous submarine cable, the Tonga-Fiji Cable System, which was damaged in 2019 and left Tonga without internet access for several weeks. The TDCE cable provides Tonga with a reliable and resilient telecommunications infrastructure, ensuring that the country remains connected to the global digital economy.
Overall, the Tonga Domestic Cable Extension (TDCE) submarine cable is a critical piece of infrastructure for Tonga, providing the country with reliable and high-speed internet access and improving its connectivity with the rest of the world.
