Optical RAMAN amplifier

RAMAN Amplifier for DWDM Transmission with optimized OSNR

  • Distances: additionally up to +30 dB optical budget
  • Optimized signal-to-noise ratio (OSNR)
  • Reduction of nonlinear distortion
  • Reduction of high-power Transceiver
  • Remote management over OSC channel
  • Supports DWDM wavelengths
  • RAMAN Amplifier for Point-to-Point Transmission with an optimized OSNR

    The use of a Raman amplifier (standalone) on the receiving side, in addition to an existing EDFA amplifier, increases transmission distances in optical neworks significantly. Therefore SPEED-AMP RAMAN reduces non-linear distortion and provides an optimized signal-to-noise ratio Working condition for a fully capability is a minimum fiber length of 50 km. The SPEED-RAMAN series provides two different types of amplifiers (standalone and master-slave) to fullfill different demands of distances, and yet compliant to laser safety class 1M. These modules are installed in space-saving housing types (SPEED-CARRIER 5U and SPEED-CARRIER 1U/B). When using multiple cards in the same segment, the acquisition of management functionality can be enabled by using an in-band OSC channel.

  • Using Master-Slave RAMAN Amplifier in order to accomplish additionally 30 dB optical Budget

    The deployment of two Raman amplifiers (master-slave) increases the transmission range of the overall system with up to +30 dB (equivalent to approximately 120 km of fiber attenuation).The RAMAN amplifier at receiving side is called „Master“ and at transmitter side is called „Slave“. An innovative safety concept has been enabled, where the master module contains the safety circuit and controls the slave module. Thus compliance to Laser Class 1M is guaranteed.
