OptiX OSN 7500II/580/550/500

Multi-Service Transmission Platforms (MSTPs) for both TDM and packet network services, optimizing processing for IP-based communications and traditional SDH services under a uniform switching architecture.

MSTP systems work in pure packet mode, pure TDM mode, and hybrid mode (packet + TDM), providing rigid and flexible channels, supporting Smart 40 GE line cards for large-bandwidth applications. All models offer the flexibility to migrate to an all-IP network, and are based on a uniform architecture to simplify maintenance and reduce O&M costs.

Optimize performance, flexibility, and manageability of ultra-broadband networks with universal transport for packet and TDM services

  • Supports multi-service access, hard and soft pipes adopt ODUk for physical isolation
  • Physical hard pipe features include strict physical isolation, low delay, low jitter, and high security
  • Soft pipe features include logical isolation, high transmission efficiency, and MPLS-TP ring protection
  • Smart 10 GE/40 GE line card software supports smooth expansion from 10 GE to 20 GE, 30 GE, and 40 GE, suitable for use in Smart “all 40 GE” large-bandwidth solutions
  • Widely used by governments and enterprises, especially in the power, transportation, and TV broadcasting industries
