Easy setup and maintenance provides flexibility and scalability for growth.

Optix PTN1900 Transmission


  • High-capacity scheduling achieves service switching capability as high as 80 Gbit/s;10 GE interface supports hard and soft pipes for high performance and low latency
  • Support for Circuit Emulation over Packet (CEP) interfaces aggregates VIP VC4 private line services
  • Device-level 1+1 redundancy protects the main control boards, cross-connect boards, and power supply modules; network-level protections include dual homing, VPN Fast Reroute (FRR), and Label Switched Path (LSP) Automatic Protection Switching (APS)
  • SDN-based design simplifies provisioning and management; O&M mechanisms include Y.1731 and MPLS-TP for rapid fault detection and monitoring device performance
  • Comprehensive QoS features tensure priority for critical services

Optix PTN1900

OptiX PTN 1900 NEs are the new generation of multi-service chassis-shaped devices applicable to the aggregation layer on packet transport networks. OptiX PTN 1900 NEs support 40GE bandwidth aggregation, adaptable to various application scenarios. They provide device- and network-level protection and reliably aggregate and forward traffic.

PTN 1900: Supports 10GE interfaces. With the integrated architecture, a PTN 1900 NE supports 1+1 redundancy protection for main control boards and power supply modules. The compact structure allows the PTN 1900 NE to support service aggregation of 10GE bandwidth.
