The OptiX OSN 2500 Intelligent Optical Transmission System is a new-generation intelligent optical transmission system developed by Huawei Technologies. The system provides high-efficiency transmission of various services, such as SDH, PDH, Ethernet, ATM, DDN, and SAN, at the core layer and edge layer. By using intelligent network technologies, the system manages the services and bandwidths intelligently. In addition, the system can be configured with a built-in IF board. Together with the microwave ODU, the system hence provides wireless transmission of services. Currently, the system supports 60 Gbit/s higher order cross-connections and 20 Gbit/s lower order cross-connections. A single subrack of the system supports up to 22.5 Gbit/s access capability, and the IF interface provided by the system provides 10 microwave directions.
Network Application
The OptiX OSN 2500 intelligent optical transmission system (hereinafter referred to as the OptiX OSN 2500) developed by Huawei is the next-generation intelligent optical transmission equipment.
The OptiX OSN 2500 integrates the following technologies to transmit voice and data services on the same platform with high efficiency:
- Synchronous digital hierarchy (SDH)
- Plesiochronous digital hierarchy (PDH)
- Ethernet
- RPR(Resilient Packet Ring)
- Asynchronous transfer mode (ATM)
- Storage area network (SAN)
- Wavelength division multiplexing (WDM)
- Digital data network (DDN)
- Automatically switched optical network (ASON)
- Microwave Technology
Capacity
The capacity covers the cross-connect capacity, slot access capacity and microwave capacity.
- Cross-Connect Capacity
Different cross-connect boards have different cross-connect capacities. - Microwave Capacity
The number of IFSD1 boards that can be configured for different types of the equipment is different. Hence, the number of microwave directions supported by different types of the equipment is also different. - Slot Access Capacity
The access capacities of slots vary depending on the cross-connect board that is configured on the OptiX OSN 2500.
Service Type
The OptiX OSN 2500 can process the following types of services : SDH, PDH, Ethernet, RPR, ATM, DDN and SAN/Video services.
Networking Topology
The OptiX OSN 2500 supports topologies such as chain, ring, tangent rings, intersecting rings, ring with chain, dual node interconnection (DNI), hub, and mesh at the STM-1/STM-4/STM-16/ level.
The OptiX OSN 2500 supports the separate and hybrid configuration of the following types of NEs:
- Terminal multiplexer (TM)
- Add/drop multiplexer (ADM)
- Multiple add/drop multiplexer (MADM)
The OptiX OSN 2500 can be interconnected with Huawei OSN, DWDM, and Metro equipment series, to provide a complete transmission network solution.
- The OptiX OSN 2500 can be used with another OptiX OSN equipment to provide a complete ASON solution. This solution covers all the layers including the backbone layer, the convergence layer, and the access layer.
- Through an SDH interface or a GE interface, the OptiX OSN 2500 can be interconnected with the WDM equipment.
- Through an SDH, PDH, Ethernet, ATM, or DDN interface, the OptiX OSN 2500 can be interconnected with the OptiX Metro equipment.
