OptiX 155/622H equipment can access a variety of service types, mainly used in metropolitan area networks, local transmission network access layer, for large customers dedicated line access, mobile base station access, DSLAM (Digital Subscriber Line Access Multiplexer) access.
For Ethernet services, the equipment supports traditional TDM (Time Division Multiplexing) and packet (Packet Transport Network) dual-domain coexistence of service bearer.
The Ethernet service in the packet service domain provides a small aggregation function from multiple FE ports to one GE port.
With the support of dual-domain networking, it can realize the smooth evolution from TDM network to packet switching network.
The application of OptiX 155/622H in the network is shown in Figure 1.
