Product Description Network Application The OptiX RTN 980 provides a generic platform for TDM/Hybrid/Packet/Routing microwave transmission, meeting the backhaul requirements of various mobile networks. The OptiX RTN 980 is large-capacity nodal microwave equipment deployed at the convergence layer. It supports the convergence of up to 20 radio links, and supports multiple protection schemes. Figure 1 shows the microwave transmission solution provided by the OptiX RTN 980. Figure 1 Microwave transmission solution provided by the OptiX RTN 980 NOTE: The OptiX RTN 980 supports a wide range of interfaces and service bearer technologies, and is therefore compatible with various backhaul networks. Specifically, packet services can be backhauled through TDM networks, and TDM services can be backhauled through packet networks. The OptiX RTN 980 can provide a route microwave solution for LTE bearer networks. In this solution, the OptiX RTN 980 functions as a CSG and works with routers that function as ASGs and RSGs to provide end-to-end L3VPN services. The routers can be Huawei CX600s or other routers. Figure 2 shows the route microwave transmission solution provided by the OptiX RTN 980. The route microwave transmission solution can be used in end-to-end Layer 3 networking. When deployed for backhauling services from a multitude of eNodeBs, the solution simplifies VLAN planning, reduces broadcast traffic, and does not require much configuration modification on the transmission network when the wireless side changes. For details, see Feature Application (L3VPN). Figure 2 Route microwave transmission solution provided by the OptiX RTN 980 Components The OptiX RTN 980 adopts a split structure. The system consists of the IDU 980 and the ODU. Each ODU is connected to the IDU 980 through an IF cable. IDU 980 The IDU 980 is the indoor unit for an OptiX RTN 980 system. It receives and multiplexes services, performs service processing and IF processing, and provides the system control and communications function. Table 1 lists the basic features of the IDU 980.
