AQ2200-271 Optical return loss module (DISCONTINUED)

Notice: This product was discontinued on Mar 31, 2011.

AQ2200-271 is a module for measuring optical return loss (ORL) of optical components such as optical filter and optical splitter. Insertion loss (IL) can also be measured simultaneously.

  • Simultaneous measurement for both ORL and IL
  • High dynamic range : 65 dB or more
  • Measurement parameters can be preset (up to 9 sets)
  • Built-in application function allows a simple operation
  • Measurement can be automated through GP-IB, LAN, or USB

Application Note

This system does not require manual reconfiguration of optical paths and adjustments of EDFA input power, and that improves measurement throughput and avoids a human error.
