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


  • PL-1000R is designed for distributed Raman amplification applications, cost-effectively extending the optical link power budget and significantly improving OSNR 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.
  • Main Benefits:-
  • Acts as terminal Raman amplifier and as inline hybrid Raman-EDFA.
  • Full remote monitoring.
  •  Eye safety feature - automatically shuts down the Raman in case of fibre interruption.
  • Detects fibre disruption or cut tens of kilometers from the pump.
  •  Integrates with PacketLight management platforms and transponder/muxponder products.
  • Counter-propagating Raman amplifier with optionally embedded booster and preamp EDFAs in 1RU.
  • Detection of open connectors and/or broken fibre up to few tens of kilometers from the pump module
