OptiX OSN 2500

Developed by Huawei for highly efficient voice and data services transmission on a single platform, the OptiX OSN 2500 offers an intelligent, next-generation optical transmission solution. Used at the access and convergence layers of the Metropolitan Area Network (MAN), the OptiX OSN 2500 can also be networked with the other Huawei equipment to optimize customer investment.


Large switching capacity

  • 60G high order, 20G low order


High integration

  • Subrack dimensions 472mm (H) x 447mm (W) x 295mm (D), 9 slots for processing boards before division of slots, 12 slots for processing boards and 8 slots for interface boards after division of slots


Flexible networking capacity

  • Supports Mesh networking with plug-and-play network nodes
  • Supports dynamic increase of rate and capacity
  • Supports various networking topologies, including chain, ring, tangent rings, intersecting rings, etc
  • Supporting maximum 2 STM-16 four-fiber MSP rings, 4 STM-16 two-fiber MSP rings, 8 STM-4 four-fiber MSP rings, 12 STM-4 two-fiber MSP rings


Carrier-class protection

  • Mesh Protection and restoration(ASON)
  • Distributed restorable rerouting protection
  • 5-level service dedicated protection scheme based on different SLA: Diamond, Gold, Silver, Copper and Iron services
  • SDH Network Protection
  • 2/4 fiber MSP Ring; 1+1, 1: n Linear MSP; SNCP/SNCMP/SNCTP; Fiber shared virtual path protection; Fiber shared MSP Ring; DNI (ITU-T G.842)
  • Service Protection
  • Ethernet: RPR, RSTP
  • ATM: VP-RING/VC-RING


Highly Reliable Design

  • 1+1 hot backup for system control boards, cross-connect and synchronous timing boards
  • 1+1 hot backup for power supply modules
  • Redundancy protection for fan modules
  • TPS protection
  • 1:n tributary protection for E1/T1/E3/T3/ E4/STM-1(e)/FE


Enterprise-focused Features

  • Intelligent ASON based Mesh network can against multi-node failures, improving network reliability by 10 times
  • Single-span transmission for a distance of 270km without a Raman amplifier, fewer REGs to reduce the network construction cost and facilitate the maintenance
  • Single-fiber bidirectional optical module to solve the problem of a lack of fiber resources, and built-in WDM to meet the large bandwidth requirements


Industry Certification

  • Pass EN 50121-4 Railway EMC certification.
