Optical units

Manageable optical multiplexer and demultiplexer

  • Managed multiplexer / demultiplexer
  • Step size 0.1 dB attenuator
  • Controls transient processes when adding channels
  • Low noise figure
  • Flat amplifying grid in C-band

Units are designed to combine separate DWDM channels in one multi-channel line DWDM signal (multiplexer) or to extract separate DWDM channels from a multi-channel line DWDM signal (demultiplexer). Optical power in each channel can be adjusted using
built-in optical attenuator. Attenuation value for each channel can be managed using a network management system (NMS). Units support up to 40 or 48 channels.
