采用菲利蒲研究的PCVD法(等离子化学汽相沉积法),已制成具有2GEz·km至40HZ·km带宽长度乘积和衰减小于0.7dB/km的1300nm波长高效率渐变折射率光纤,从而为长途网路的应用提供了一种能高速率传输、中继距离大的传输介质.整套系统最终可能实现的中继距离主要由所用光缆
The PCVD method (Plasma Chemical Vapor Deposition), which is based on the Phillips study, has been fabricated into a 1300 nm wavelength high efficiency graded-index optical fiber with a product of the bandwidth length of 2 GEz-km and 40 Hz-km and an attenuation of less than 0.7 dB / km, The application of long-distance network provides a transmission medium capable of high-speed transmission and large relay distance.The final possible trunk distance of the entire system mainly consists of the cable
