moment. In the metro backbone network, the IP over SDH technology has a relatively high investment, so it is more practical to use the IP over WDM Technology. The advantage of IP over WDM is to reduce the intermediate redundancy between different layers of the network, reduce overlapping functions between SDH, ATM, IP, and other layers, and reduce equipment operation, maintenance, and management costs. In addition, the IP over WDM Technology can grea

upstream and downstream transmission channels of the cable TV HFCs are symmetric. Because the downstream channel is broadcast, it has good transmission characteristics and high signal-to-noise ratio, it can fully meet the technical requirements of communication and transmission. However, data transmission emphasizes two-way interaction. When users receive information, they also need to return personal info
