800G transponder in 1U, for high capacity applications


  • PL-2000T is a modular and cost-effective solution for rolling out 100G services or increasing existing network capacity. The device has four 200G pluggable optical modules, delivering up to 800G in a 1U chassis, and enabling pay-as-you-grow architecture.
  • Solution provides full demarcation point between the service and the uplink DWDM side and is interoperable with any third party switch or router. This provides full visibility and performance monitoring of both line optical transport layer (OTN) and 100G LAN/OTU4 service interfaces.
  • Integrated EDFA, mux/demux and optical switch in 1U
  • High transport capacity of 800G with configurable modulation scheme
  • Embedded Layer-1 optical encryption
  • Managed service platform
  • Modular and cost-effective for future growth and maintenance
  • Pay-as-you-grow architecture based on pluggable 200G digital coherent optical modules
