石器,在人类进化的过程中,曾发挥过至关重要的作用,随着各种金属的冶炼成功而被日渐冷落。面对举目可见的石头,于是有了点石成金的神话。 铜线,在通信发展的历史中,曾担任重要角色。而今,各种大容量、高速率传输方式的应用,似乎使其风光难再。然而,美国培尔根公司的HDSL技术,却可使铜线传输质量接近光纤,传输速率达到2Mbit/s,成为高速数字用户环路方面的佼佼者。 借上海第八届国际信息通信展之际,我们采访了培尔根技术公司北亚区经理梁永辉先生。
Stoneware, once played a crucial role in the evolution of mankind, is gradually cooling off as the smelting of various metals succeeds. The face of visible stone, so there is a golden stone myth. Copper wire has played an important role in the history of communications. Now, a variety of high-capacity, high-speed transmission of the application seems to make it difficult to scenery. However, the U.S. high-end HDR technology from Pärrgen can make copper transmission quality close to the optical fiber and the transmission rate reaches 2Mbit / s, becoming the leader in high-speed digital subscriber loop. On the occasion of the 8th International ICT Exhibition in Shanghai, we interviewed Mr. Liang Yonghui, manager of North Asia Division, Peilgen Technologies.
