AQ2200-411 Optical Switch Modules (1 x 4 / 1 x 8)

Compact optical switches, Superior switching reproducibility

Yokogawa AQ2200-411 Optical Switch Module


  • Compact: Optical switches of 1 x 4 or 1 x 8 port configuration in a one-slot size module
  • Compatible with SMF (core diameter of 10 µm) or MMF (core diameter of 62.5 µm)
  • Low insertion loss: 1.0 dB (typ.)
  • High switching reproducibility: within ±0.01 dB
  • Can be combined with various AQ2200 series modules or other Yokogawa’s optical communication measuring instruments to build versatile measuring systems


  • For measuring multiple objects, with switching of the object to be measured
  • For measuring device characteristics, etc. by switching multiple measuring instruments
  • For building a measurement system in combination with a bit error tester, etc.


The AQ2200-411 OSW module is a space-saving optical switch featuring low insertion loss and superior switching reproducibility, and allows selection of 1 x 4 or 1 x 8 port configuration according to the application.
Moreover, the optical fiber type can also be selected between SMF (core diameter of 10 µm) and MMF (core diameter of 62.5 µm), allowing a wide range of measuring systems to be built corresponding to the systems or devices used in optical public networks or optical LANs.
