The Micron Optics' sm040 Channel Multiplexer adds sensor and optical-fiber-connection capacity to the si425-500 Optical Sensor Interrogator.

There are two basic types of sm040. First is the switch-type (sm040-416 and -408). Robust optical switches can be programed to alternate between multiple banks of sensors. This boosts capacity of the si425-500 Optical Sensor Interrogator to up to 16 fibers and more than 2000 sensors.

The second type of sm040 Channel Multiplexer is the coupler-type (sm040-016 and -008). Coupler-type extensions provide a tidy way to connect up to four optical fibers to a single optical channel on the si425-500 Optical Sensor Interrogator. For many applications this can greatly simplify fiber routing and sensor installation.

Micron Optics supplies a LabVIEW™ utility example that provides the user a path to customize the use of the additional channels provided by the switch-type extension. No special software is needed for the coupler-type sm040.

Applications

  • Strain measurements for structures requiring hundreds or thousands of fiber-optic sensors.

  • Large sensing applications requiring 8 to 16 optical fibers.
