Fiber Bragg Gratings

FBG Instruments


INFIBRA TECHNOLOGIES can offer a range of FBG interrogators based on the different technologies provided by its international partners. Listed below you can find the proprietary instruments only, click on the picture in a selected tab to read the specifications.

 

fbg hub unit miniatureFBG.HUB UNIT is an optical multiplexer which can be used in combination with FBG interrogators for the acquisition, log and communication of FBG-based sensors. Each of 4 input channels can be connected to a channel of a compatible FBG interrogator in order to expand the acquisition channel from 1 to 16. This capability allows the acquisition of 4 x 16 = 64 switched channels.
