MN Series

The SpectralWave MN Series is a family of new-generation MSTP SDH optical systems with features for next-generation networks, including SDH, ATM, RPR, and Ethernet over SDH services. These total solutions for optical transport provide integrated network control for various customers and/or regions on a common system platform and can interconnect with multi-vendor systems based on ITU-T specifications.

From Access to Backbone

Features

  • Scalable cross-connect capacity
  • Comprehensive multi-service platform
  • Ethernet and RPR (MN2200, MN2300, MN3100, MN4100)
  • High-speed, high-density backplane
  • ASON (MN4100)
  • GMPLS (MN4100)
  • ATM (MN3100, MN4100)

Benefits

Various service interfaces
Support for transmission speeds from 155Mb/s to 10GB/s Multi-rate integrated transport for TDM, 10/100/1000M Ethernet, RPR and ATM services eneric framing procedure (GFP) for Ethernet, fiber channels, etc.

Effective bandwidth utilization
Link capacity adjustment scheme (LCAS) for efficient bandwidth usage

High reliability
Many network schemes are realized on the SDH layer (protection switching time < 50ms) SP+SNCP, 2/4 fiber MS-SPRing, DNI protection, 2 node BLSR, fiber-shared virtual ring protection Resilient packet ring (RPR) technology with wrapping/steering in up to 64 nodes Load sharing: Multiple spanning tree protocol (MSTP) IEEE802.1s High-speed failure recovery: Spanning tree protocol (STP) IEEE802.1d and rapid spanning tree protocol (RSTP) IEEE802.1w

Scalability and upgradeability
The MN9100 network management system enables automatic in-service network reconfiguration for expansion and upgrading. No manual operation is required, for example, when upgrading from 2.5G MS-SPRing to 10G MS-SPRing.
