Product Description Network Application The OptiX RTN 905 provides a generic platform for TDM/Hybrid/Packet/Routing microwave transmission, meeting the backhaul requirements of various mobile networks. The OptiX RTN 905 is access-layer microwave equipment. It can independently constitute a network or jointly constitute a network with the OptiX RTN 910/910A/950/950A/980. Figure 1 shows the microwave transmission solution provided by the OptiX RTN 905. Figure 1 Microwave transmission solution provided by the OptiX RTN 905 NOTE: In this solution, services accessed by the OptiX RTN 905 can be backhauled by the OptiX RTN 950/950A/980/910A after being converged at air interfaces, or be directly backhauled by the OptiX RTN 905. When three or more microwave directions are required, cascade several sets of the OptiX RTN 905 or use the OptiX RTN 950/950A/980/910A that provides more powerful functions and supports more microwave directions. The OptiX RTN 905 can provide a route microwave solution for LTE bearer networks. In this solution, the OptiX RTN 905 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 905. 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 905 Components The OptiX RTN 905 adopts a split structure. The system consists of the IDU 905 and the ODU. Each ODU is connected to the IDU 905 through an IF cable. IDU 905 The IDU 905 is the indoor unit for an OptiX RTN 905 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 905. Table 1 Features of the IDU 905 Item Description Type IDU 905 1E IDU 905 2E Chassis height 1U Extended subcard Supported Service interface 4 x GE electronic interface 4 x GE/FE optical interface or GE electrical interface (SFP)b 2 x 2.5GE optical interface(SFP+/SFP)c 16 x E1 interface 1 x multifunction cascading interfacea, b 1 x E1 services cascading interfaceb 2 x STM-1 interface NOTE: a: IDU 905 1Es can be cascaded through multifunction cascading interfaces to implement 1+1/XPIC/PLA/EPLA function, or transmit E1 services. IDU 905 2Es can be cascaded through multifunction cascading interfaces to implement EPLA function, or transmit E1 services. b: Two of GE interface (SFP) and two cascading ports share same physical ports (combo ports). When cascading is not used, the two combo ports can be set as GE ports. c: Both port GE5 and port GE6 support 2.5GE optical modules. If either port GE5 or GE6 needs a 2.5GE optical module, insert 2.5GE optical modules into both ports.
