文章描绘了采用波分复用(WDM)技术的F-6M(6Mb/s)光纤传输系统。该系统主要用于小容量市内通信线路,在一根光纤中以1.2和1.3 μm两个波长传送6.3Mb/s数字信号,并于1983年10月开始商业性试用。该系统对减少通信网络费用,提高其质量都将是有效的,并有助于通信网络数字化。
The article describes the F-6M (6Mb / s) optical fiber transmission system using Wavelength Division Multiplexing (WDM) technology. The system is intended for small-capacity municipal communications lines and delivers 6.3Mb / s digital signals at 1.2 and 1.3 μm in one fiber and commercial trial started in October 1983. The system will be effective in reducing the cost and improving the quality of the communication network and will facilitate the digitization of the communication network.
