Huawei SDH Optical Transceiver_ Optix Metro2050 ( Metro3000 ) STM-16 MADM/MSTP Optical Transmission System (hereinafter referred to as OptiX2500+) is a multi-service transport platform (MSTP) equipment. This equipment integrates SDH/ATM/Ethernet/DWDM technologies; it not only has the flexible networking and service scheduling capability (MADM) of SDH equipment, but also realizes the access, processing, transmission and scheduling of ATM/Ethernet services through the second-layer processing of data services, so as to realize the transmission and processing of multiple services, such as voice, data, etc., on a single piece of equipment. + Details Metro3000 system configuration is quite flexible, each network element can be configured either as a single STM-4/STM-16TM or ADM system, or as a MADM system with a combination of STM-1, STM-4, and STM-16 interfaces, which realizes cross-connection between multiple systems and has the ability to smoothly transition from TDM services to data services. The system adopts large-scale cross-connection matrix and robust software design to provide fast and reliable network protection by utilizing the function of self-healing of MADM ring network, and at the same time, it adopts distributed scheduling to change the centralized scheduling function of the original service to be accomplished by multiple MADMs with full cross-connection capability in cooperation, so as to reduce the complexity of the network structure. The equipment meets the needs of various network topologies, including point-to-point, linear, ring, mesh, and other complex networks and large-scale networks, and can also be used as the aggregation and transmission of services at the edge and access layer in MANs, realizing the provisioning and routing protection of various integrated services in complex networks.

Metro2050 meets diversified service requirements with three rings in one

Metro2050 is based on the design of MSTP platform: it adopts embedded RPR technology to realize three logical rings, namely, RPR ring, SDH ring, and ATMVP ring, on one physical ring, which provides bandwidth sharing of the ring and realizes statistical multiplexing of bandwidth in the whole ring. Optional encapsulation protocols and adjustable mapping granularityThe Ethernet single board provides three encapsulation protocols, GFP/LAPS/PPP, and the encapsulation protocol can be selected through the network management settings. In the case of different encapsulation protocols of various manufacturers, this feature greatly improves the interoperability of the network. Ethernet single board provides VC12/VC3/VC4 mapping particles, and the number of mapping particles can be flexibly adjusted according to the needs. This feature fully meets the needs of customers for dynamic adjustment of data service bandwidth. Provide a variety of Ethernet service modes Ethernet single board provides a variety of Ethernet service application modes: pass-through, aggregation, ring sharing mode; for the widely used aggregation mode can be realized: FE -> FE, FE -> GE, GE -> GE service requirements, to fully meet the user's business needs. The most powerful Ethernet port aggregation capability Ethernet port aggregation capacity of the strongest Ethernet single board to provide FE services up to 24:1, GE services up to 48:1 aggregation capacity, the industry's strongest specifications. The port aggregation capability enhances the networking capability of the equipment and minimizes the investment cost of users. Especially for private line services, the stronger the port aggregation capability, the more ports can be saved, thus saving the user's investment. The customer-friendly full data function provides key functions such as embedded RPR, LCAS link capacity adjustment mechanism, CAR committed access rate, Ethernet Layer 2 switching, etc., which enhances the service processing capability and improves the QOS capability of the service. The equipment also provides complete ATM functions to meet the service requirements of full data. Reliable and Complete Protection Methods to Enhance Network Survivability The Metro3000 system provides complete service protection methods:

Metro2050 device-level protection:

Key units (crossover, clock, power supply) support 1+1 hot backup equipment protection; TPS protection: support 1.5M/2M/34M/45M/155M 1:n branch protection, and support 2M and 155M mixed 1:n protection (n<=8). TPS protection turns passive protection into active protection, revitalizes assets, and improves network security. Network level protection 2F/4F MSP, PP, SNCP, DNI, Shared Fiber Virtual Path Protection Metro2050 Shared Fiber Virtual Path Protection adopts shared fiber virtual path protection according to the division of logical subsystems in order to improve the survivability of the SDH network and the utilization of bandwidth resources, i.e., the bandwidth resources provided by each optical fiber are arbitrarily divided according to the unit of VC4, which are assigned to different logical subsystems. The bandwidth resources provided by each fiber are divided arbitrarily according to the unit of VC4 and assigned to different logical subsystems, and each logical subsystem can independently choose different protection modes in accordance with the characteristics of the transmission service, so that an optical fiber can support multiple protection modes at the same time, so that the service can be optimally protected. Network-level link layer service protection provides ATM VP-Ring protection for ATM ring services to ensure reliable transmission of services and strengthen network survivability, and RP-Ring protection for Ethernet ring services to strengthen network survivability.
