  • 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

How do Fiber Optic Switches Work?

To evaluate GE-PON systems used for FTTH networks, optical characteristics and IP traffic tests are performed. Since a GE-PON consists of OLTs and multiple ONUs, efficient measurement of multiple ports is required. Utilizing the multiple port AQ2200-4xx high speed optical switch makes it possible to build an efficient automated measurement system by distributing the signal in a custom test network. With the fiber optical switch module, a multi-fiber loss measurement system can be easily configured.


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(10/125µm) and MMF(50/125 µm, 62.5/125 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.
