武汉院试验场最近成功地实现了四次群(140Mb/s)60.5 km无中继光通信系统实验,整个系统主要特性如下:光源采用武汉电信器件公司研制的InGaAsP/InP—DAL—DC—PBH—LD组件其工作波长为1.52μm,主/旁模抑制比为15dB,光谱半宽度为1(?)。光纤采用院光纤光缆室研制的单模光纤,为了研究对现有1.3μm系统扩容等,全部光纤均为供1.3μm系统使用的单模光纤,光纤总长60.5km,在1.55μm处的总
Wuhan Institute test site recently successfully achieved a four-group (140Mb / s) 60.5 km repeaterless optical communication system experiment, the main features of the system are as follows: light source by Wuhan Telecom Device Company developed InGaAsP / InP-DAL-DC-PBH The -LD package has an operating wavelength of 1.52μm, a main / by-mode rejection ratio of 15dB, and a spectral half-width of 1 (?). In order to study the expansion of the existing 1.3μm system, all of the optical fibers are single-mode optical fibers used for the 1.3μm system. The total length of the optical fibers is 60.5km and the total length of the optical fibers at 1.55μm
