OptiX PTN 1900 Transmission Systems

Highly reliable, mid-range transmission platform for use in Packet Transport Networks (PTNs) to aggregate and forward traffic with comprehensive device and network-level protection features.

Excellent choice for aggregation layer of metropolitan transmission networks, supporting CES, ATM, Ethernet, IP over PW, and L3 VPN services; supports 80 Gbit/s capacity and 40 GE interfaces.

Easy setup and maintenance provides flexibility and scalability for growth.

High-availability transmission engine with comprehensive management and security features optimized for use at the aggregation layer in Packet Transport Networks

  • 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 Re-Route (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 ensure priority for critical services
