据日本富士通研究所称,该所已经掌握了传输量40Gbit/s的下一代高速光通信传输技术。具体说就是研制了将高速信号传输到用于通信的激光束上的装置,并证实了其性能。据认为,将争取于2000年时在东京—大阪之间等的光通信网干线上运用40 Gbit光通信技术。 以40 Gbit/s的传输速率,可以在1 rain内把一份报纸10年刊登的信息量传输过去。新研制的装置叫做“变调 According to Japan’s Fujitsu Research Institute, the institute has mastered the next generation of high-speed optical communication transmission technology with a transmission capacity of 40 Gbit / s. Specifically, a device for transmitting a high-speed signal to a laser beam used for communication was developed and its performance was confirmed. It is believed that 40Gbit optical communication technology will be applied to the optical communication network trunk lines between Tokyo and Osaka in 2000. With a transmission rate of 40 Gbit / s, it is possible to transmit the amount of information that a newspaper has published for 10 years within 1 rain. The newly developed device is called "change
