提出了一种将多路快速以太网信号复用为千兆位信号，在主干网上传输至接收端再解复用成原来信号的方法，达到了利用现有设备扩容的目的。针对 １００ＢＡＳＥ－ＴＸ信号给出了一种复用方案，并对其中关键的同步技术进行了研究。该方案已应用于硬件实现，效果良好。
A method of multiplexing multiple fast Ethernet signals into gigabit signals and transmitting them to the receiving end in the backbone network to demultiplex them into original signals is proposed to achieve the goal of utilizing existing equipment for capacity expansion. A multiplexing scheme is given for the 100BASE-TX signal and the key synchronization technique is studied. The program has been applied to the hardware implementation, the effect is good.
