Compact: Optical switches of 1 x 4 or 1 x 8 port configuration in a one-slot size module Compatible with SMF(10/125µ,m) or MMF(50/125µ,m, 62.5/125µ,m) 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
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(10/125µ,m) and MMF(50/125 µ,m, 62.5/125 µ,m), allowing a wide range of measuring systems to be built corresponding to the systems or devices used in optical public networks or optical LANs.''
