United States submarine cable bandwidth will increase 31 times
Between China and the fiber optic cable transmission capacity can be increased more than 30 times of trans-Pacific direct fiber optic cable system (Trans-PacificExpress TPE for short) are from the blueprint into reality. China Netcom persons external for the first time yesterday disclosed that TPE Qingdao access points of a groundbreaking ceremony will be held in early September and begin cable laying work.
In December last year, from Central America and South Korea’s six largest telecommunication company in Beijing signed an agreement to jointly invest US $ 500 million to build the trans-Pacific direct fiber optic cable system. This is the world’s first undersea high-speed direct access to fiber optic cables. According to the China Netcom, say its bandwidth reaches 5120G, submarine cable bandwidth than existing connections between China and the increase of about 31 times.
And the submarine cable no longer bypass Japan, from Shanghai and Qingdao is attached directly to the United States, Oregon, has two branches respectively links to Korea huge helped and China Taiwan fresh water in the North of the island.
According to the plan, TPE for completion in the third quarter of 2008., Sino-US submarine cable between China and the massive information mainly through transmission, limit capacity just 160G. and because the bypass Japan, which greatly affected the speed.
At the same time, TPE are all routed in last year, Taiwan strong earthquake occurring outside the region, avoided the issue of submarine cable route in the past are somewhat concentrated, dispersed the risk of natural disasters caused by interruption of communications. early hours of the night of December 26 and 27th of last year, Taiwan area that a strong undersea earthquake, causing multiple submarine cable in the sea area earthquake fault, tens of millions of Chinese Internet users for over a month period does not go online.
