Based on unified switching and hybrid line card, it realizes intelligent transmission of Ethernet, SDH/ " target="_blank" >ATM, TDM and other services in any proportion; it realizes unified switching of packet and TDM services at any level with high efficiency and high performance, and the bandwidth is "0". Waste

Intelligent line card single optical port unified transmission of packet and TDM services, to achieve the evolution of different types of services between the worry-free, "0" waste of investment

2.PID enables customized metro ultra-wideband transmission

A single PID chip integrates the functions of OTU, MUX, DEMUX and other boards to provide 40G/100G capacity of a single optical port; SDH-like OAM, no need for complex optical layer design (e.g., wavelength planning and OSNR calculations), no need for complex optical fiber connection operations, greatly reducing the time for service turn-up; space savings of 50%, energy consumption savings of 40%.

3. Hard and Soft Pipes Realize High Reliability and High Efficiency Transmission

Traditional SDH hard pipeline, high-quality and low-latency transmission of TDM services, to ensure reliable transmission of production scheduling services and leased line services; MPLS-TP-based packet soft pipeline, supporting packet statistical multiplexing, to ensure efficient and reliable bearing of large-bandwidth data services; Unified switching-based soft and hard pipelines, taking into account the existing network services and future IP services, to achieve smooth evolution of the transmission network.

4.TP assistant simplifies operation and maintenance

MPLS-TP-based OAM solution - "TP Assistant" provides efficient planning, rapid deployment and easy maintenance capabilities, making large-scale packet network easy to manage; network-level visualization view, graphical display of end-to-end service configuration, Network-level visual view, graphical display of end-to-end service configuration, path performance monitoring and status; better maintenance experience than SDH: visual end-to-end bandwidth management, intelligent location of 92% of faults, analyzable and predictable network management.

5. Industry certification; certified by the electromagnetic compatibility (EMC) standard (EN 50121-4) for the railroad industry.
