A few days ago, the second phase expansion project of the Trans-Pacific Direct Submarine Cable System (TPE), which China Unicom participated in the construction of, successfully passed the acceptance test and was officially put into use. After the expansion, the TPE The design capacity has been increased by 100G, from the original 2.56Tb/s to 22.56Tb/s, which has greatly improved China Unicom’s international access capabilities in the Pacific region, met the growing demand for communication services in Asia and North America, and reduced the Network latency internally and in hotspots on the east and west coasts of the Pacific.
TPE submarine cable system is a large-capacity international submarine optical cable system connecting mainland China, Taiwan, South Korea, Japan and the United States , is one of my country's important trans-Pacific submarine cables. It is my country's main submarine cable that reaches directly to North America. It is responsible for a large number of international business from my country to North America and has a very important communication and strategic position.
This expansion project newly introduced submarine cable terminal equipment from Ciena Company, with 12,000 kilometers of submarine cable sections and 80 kilometers of submarine repeaters The 100Gb/s transmission technology was successfully implemented over the span and smoothly connected with the 10G wavelength division system of TESubcom, making TPE the first high-speed and large-bandwidth international submarine cable with the longest span to be officially put into use in mainland China. system.
