第一代横跨大西洋海底光缆TAT-8,仍在敷设过程中。但显然,TAT-8已不够人们使用。目前,四个国家的通信公司已签订了一项初步协议,建立第九条横跨大西洋海缆(TAT-9)系统。据ATT公司发言人Richard Brayall说,这项协议。由美国ATT公司、加拿大Teleglobe公司、英国Telecommu-nications International公司、法国Secretariat for Posts and Telecommunications公司和西班牙Telefonica公司的代表在巴黎签署,它将促使TAT-9系统由计划阶段进入研制阶段。各公司指望这条光缆能于1991年投入使用,它将连接加拿大、美国、英国、法国和西班牙,预计耗资4亿美元左右。与TAT-8(预期在1988年6月竣工)一样,TAT-9也是在二个光纤对上传输。它将使用更先进的技术,传输速率可达565
The first generation of transatlantic submarine cable TAT-8 is still in the process of laying. But obviously, TAT-8 is not enough for people to use. At present, four countries’ communications companies have signed a preliminary agreement to establish a ninth transatlantic cable (TAT-9) system. According to ATT spokesman Richard Brayall, the agreement. It was signed in Paris by representatives of American ATT, Teleglobe of Canada, Telecommu-nications International of the United Kingdom, Secretariat for Posts and Telecommunications of France and Telefonica of Spain. It will prompt the TAT-9 system to enter the development stage from the planning stage. Companies expect that this cable will be put into use in 1991. It will connect Canada, the United States, the United Kingdom, France and Spain and is expected to cost around US$ 400 million. Like TAT-8 (expected to be completed in June 1988), TAT-9 is also transmitted over two fiber pairs. It will use more advanced technology and transfer rates up to 565
