Counter-propagating Raman amplifier and hybrid Raman-EDFA in 1U platform



Raman amplifier designed for distributed amplification applications

  • Acts as terminal Raman amplifier and as inline hybrid Raman-EDFA.
  • Full remote monitoring.
  • Automatically shuts down the Raman in case of fibre interruption.
  • Integrates with PacketLight management platforms
  • Counter-propagating Raman amplifier with optionally embedded booster and preamp EDFAs in 1RU.
  • Detection of open connectors and/or broken fibre


The PL-1000R is designed for distributed Raman amplification applications, cost-effectively extending the optical link power budget and significantly improving OSNR(Optical Signal to Noise Ratio) for building long distance DWDM solutions. It provides amplification for a range of optical solutions and incorporates several configurations of Raman amplifier, including counter-propagating and hybrid Raman-EDFA.

Raman amplifier


The PL-1000R is fully managed, configured and monitored remotely as part of the network, via optical supervisory channel (OSC) or Inband (GCC). The Raman is controlled, adjusted and monitored by the user.

PacketLight’s NMS provides comprehensive visibility and control over network infrastructure, enabling administrators to ensure optimal network performance, security, and reliability. The NMS enables administrators to monitor the equipment on the network, track traffic, detect and resolve issues, and configure network devices remotely.


The Raman includes three eye safety mechanisms that shut down the unit in case of fiber link disruption, such as open connectors or broken fibre, even at a distance of a few tens of kilometers from the unit.
