AQ2200-621/622 Optical Modulator (DISCONTINUED)

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

The AQ2200-621 and AQ2200-622 are optical modulator modules designed for use with the AQ2200 Series AQ2200-601 BERT Module. The PPG electrical signal from the AQ2200-601 BERT Module is modulated to Optical Signal. The AQ2200-621 and AQ2200-622 should be used together with the AQ2200-111 optical light source module (PMF option).

  • Extinction ratio adjustment function (6 dB to 12 dB)
  • Be sure to use an oscilloscope to establish the relationship between the setpoint and extinction ratio before using the output light Extinction ratio.
  • Cross point adjustment function
  • Auto-Bias Control ON/OFF function
  • Bias Slope switching function
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.
