Adaptability to the existing fiber network The existing fiber networks mostly use G.652 fiber, the dispersion problem must be resolved for 10Gbit/s service on standard G.652 fiber. ZXMP S390/ZXMP S380 has advanced dispersion management to improve fiber adaptability, especially the adaptability to the existing G.652 fiber network. Excellent timing synchronization processing ZXMP S390/ZXMP S380 can select multiple timing sources as equipment timing reference: external clock, clock extracting from STM-N service interface and internal clock. Timing system has three working modes: synchronous locking mode, hold-on mode and free-run mode. The system supports synchronous priority switching and SSM algorithm-based automatic switching. In the complex transmission network, the SSM algorithm-based automatic switching can optimize the timing synchronization distribution of the network to reduce synchronization planning difficulty, avoid timing loop and assure the network synchronization in the best status. And ZTE’s SDH products have the patented S1 byte algorithm to raise and optimize network synchronization. Powerful RPR data features to support IP evolution and protect CAPEX for the future On the basis of the inherited MSTP advantages, RPR resolves some problems about EOS rigid tunnel and low carrying efficiency for high-convergence-ratio data service. It has bandwidth statistical multiplexing and service awareness functions and offers differential QOS. The embedded RPR solution makes full use of equipment in the existing network to meet the recent increasing demands for data service, reduce network construction cost and protect CAPEX for the future network evolution. Support mixed slot insertion and optimize equipment configuration and network planning flexibly When multiple rings is established flexibly, line boards can be configured randomly without slot pair, and network configuration and planning can be optimized easily to improve network flexibility. General design of service board to reduce the cost of spare boards and parts ZXMP S390/ZXMP S380 adopts the general design of service boards to share spare boards and parts so as to reduce the cost.
