Electrical and Digital Driven Attenuators


Key Features

  • Channel-by-channel attenuation (equalization) or blocking
  • Dynamically and remotely controlled by software
  • Wide channel pass band
  • High extinction ratio
  • Excellent temperature stability
  • Compact packaging size


Wavelength blockers are critical devices for reconfigurable OADM solutions and for applications where dynamically blocking and balancing per-channel power is required. This unit can be remotely configured to block any combination of wavelengths and simultaneously attenuate the express wavelengths.

It provides the customer with maximum flexibility to dynamically reconfigure the channels to be dropped or passed through at an OADM node. Wavelength blockers are based on Oclaro's proprietary technology platform.
