The AQ2200-312 is a variable optical attenuator type for the AQ2200 series. When it is installed in an AQ2200 series frame controller, it allows optical output to be attenuated to any value.

• Wide attenuation range:
  • 0 to 60 dB (SM version)
  • 0 to 45 dB (MM version)
• Wide wavelength range:
  • 1200 to 1700 nm(SM version)
  • 800 to 1370 nm (MM version)
• Compatible with SMF(10/125µm) or MMF(50/125µm, 62.5/125µm)
• Low insertion loss: 1.0 dB (typical)
• Low polarization dependence loss: 0.1 dBp-p or less
• Monitor output (optional)
• Configure the desired measurement system by combining AQ2200 Series modules with Yokogawa optical communications measuring instruments
