OptiX OSN 3500 II

Offering an intelligent, next-generation solution, the OptiX OSN 3500 II optical transmission system was developed by Huawei to efficiently transmit voice and data services on a single platform. Primarily deployed at the convergence and backbone layers of the Metropolitan Area Network (MAN), the OptiX OSN 3500 II can also be networked with other Huawei equipment to optimize customer investment.

Large switching capacity

  • 120G high order, 20G low order

High integration

  • Subrack dimensions 722mm (H) x 436mm (W) x 295mm (D), 15 slots for processing boards and 20 slots for interface boards

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 1 STM-64 four-fiber MSP rings, 2 STM-64 two-fiber MSP rings, 9 STM-16 four-fiber MSP rings, 12 STM-16 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

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 lack of fiber resource, and built-in WDM to meet the large bandwidth requirement

Industry Certification

  • Pass EN 50121-4 Railway EMC certification.
