OptiX PTN 3900 Products Brochure

3900 NEs are the new generation of multi-service chassis-shaped devices applicable to the aggregation layer on packet transport networks. 3900 NEs support 40GE bandwidth aggregation, adaptable to various application scenarios. They provide device- and network-level protection and reliably aggregate and forward traffic.

PTN 3900-8/3900: Supports 40GE interfaces. A PTN 3900-8 or 3900 NE meets the high-bandwidth aggregation requirement. A PTN 3900-8 or 3900 NE has a distributed architecture with the separate control and forwarding planes. The NE provides 1+1 redundancy protection for the main control boards, cross-connect boards, and power supply modules. The PTN 3900-8 or 3900 NE provides high reliability and high-capacity aggregation.

Product Characteristics

High-Bandwidth Aggregation:

  • Supports the 640 Gbit/s capacity and 40GE high-bandwidth interfaces, which aggregate high-bandwidth services.
  • Supports Circuit Emulation over Packet (CEP) interfaces used to aggregate VIP VC4 private line services.
  • Supports various types of interface, such as E1, FE, GE, STM-1, and STM-4 interfaces.

Storing Environment Adaptability

  • Uses a subrack with the depth of 300 mm (11.81 in.), which is applicable to an ETSI cabinet with the depth of 300 mm (11.81 in.).
  • Provides a heat dissipation system with better performance and minimized noise.
  • Has low power supply consumption and supports two 63 A power supply modules.

High Reliability:

  • Provides high-reliability device-level 1+1 redundancy protection for main control boards, cross-connect boards, and power supply modules, which ensures that the device is running stably.
  • Supports various network-level protection functions, such as dual homing, virtual private network (VPN) fast reroute (FRR), and label switched path (LSP) automatic protection switching (APS), to reliably forward services.
  • Supports industry-leading ring protection that protects traffic from multi-node faults.
  • Supports operation, administration and maintenance (OAM) mechanisms, such as Y.1731 and Multiprotocol Label Switching Transport Profile (MPLS-TP), which rapidly detect fault and monitor device performance.
