Yokogawa Electric Corp.'s AQ2200-412 is a 1 x 16 low insertion loss optical switch for use in automated test systems.

The new unit contains 16 ports in a two-slot size module, and allows from one to 16 DUTs to be connected to test instrument modules in Yokogawa's AQ2200 Series modular optical instrumentation system. As a result, different automated test configurations can be developed for the testing of active and passive optical components.

The AQ2200-641 expands the flexibility of the AQ200 Series multi-application test system and reduces the total measurement time for both active and passive multiport component tests. It features a low insertion loss of typically 1dB and a very low polarization-dependent loss of 0.08dB p-p. Thus, the switch passes most of the light power through the DUT, ensuring that polarization-dependent loss has virtually no influence on the measurement's accuracy.

Other key features of the unit include excellent reproducibility (within (0.01dB) to support high-accuracy measurements without the need for frequent reference measurements and low crosstalk (-60dB or less) between neighboring channels.

The AQ2200-412 can be used with either the Yokogawa AQ2201 3-slot mainframe or the AQ2202 9-slot mainframe to form a complete compact optical measurement system that optimizes the use of laboratory bench space.

The AQ2200 Series is equipped with standard interfaces such as USB, LAN, IEEE and flash card memory. It is supported with 'hot-swappable' plug in units including a high-stability light source, a wideband tunable light source, a high-speed optical sensor with low PDL and a high-resolution variable optical attenuator.
