Nowadays, the rapid development of data services has led to an increasing speed of IP network convergence, so network expansion is very important. In the construction of metropolitan area networks, there is a widespread problem of optical fiber shortage. Because metro expansion requires less channel numbers than trunk systems, and the distance is relatively short, optical amplification is not requ...
