Chunghwa Telecom introduced on Friday that the Taiwan-Matsu submarine cable (Taima No. 4) has been activated, including redundancy and resilience to the Web connection within the island nation’s outlying islands.
The Matsu Islands are situated within the Taiwan Strait, only a few kilometers off the southeastern coast of mainland China and near town of Fuzhou in Fujian Province. They type a part of Lienchiang County, which is the smallest county in Taiwan.
The brand new Taima No. 4 subsea cable, which is partly backed by the Taiwanese authorities, was constructed at a price of 1.4 billion New Taiwanese {dollars} (US$44 million). The 300-kilometer cable connects Bali District in New Taipei with Dongyin, Nangan and Juguang townships in Lienchiang County.
It was constructed following the cable breaks on the Taima No. 2 and Taima No. 3 in February 2023, which disrupted information transmissions for nearly two months. These high-profile incidents have been attributable to a Chinese language fishing boat and a cargo ship. In 2025, these two subsea cables went down once more, this time resulting from “pure deterioration.”
Based on Chunghwa Telecom, Taima No. 4 supplies a further communications route, decreasing the chance of serious future disruptions and enhancing the general reliability of the Web for Matsu residents.
With the addition of Taima No. 4, whole transmission capability within the Taiwan-Matsu route has elevated to 1.9 Tbit/s.
To make sure the Matsu Islands stay linked within the occasion of a subsea cable failure, Chunghwa Telecom has put in backup programs comprising microwave and satellite tv for pc communications.
‘Pre-emptive preparations’
Throughout the lighting-up ceremony for Taima No. 4, Taiwanese Premier Cho Jung-tai stated that the brand new subsea cable was supposed to strengthen communication resilience, describing it as a part of “pre-emptive preparations.”
He stated that the brand new subsea communications cable was a part of the federal government’s efforts to stabilize and bolster information transmission and guarantee continuity throughout pure disasters or man-made occasions.
“Wanting forward, whether or not it’s subsea cables, microwaves, or low-orbit satellites, capability will far exceed demand right here. We’re making pre-emptive preparations,” Cho stated, as quoted by Focus Taiwan.
