Product Overview of OFSCN® Fiber Bragg Grating Interrogator

The OFSCN® Fiber Bragg Grating (FBG) Demodulator is a flagship optoelectronic analysis device integrating high-speed sampling, high-precision detection, and multi-channel expansion. Acting as the "brain" of the FBG sensing system, the device emits broadband laser light, demodulates reflected wavelength signals, and converts them into precise data for temperature, strain, pressure, or displacement.

The device offers exceptional compatibility, perfectly matching the full range of OFSCN® FBG sensors and bare gratings (strings), as well as third-party C-band (1525 nm to 1565 nm) products. Its highly customizable nature allows it to excel in tasks ranging from high-end laboratory research to extreme industrial monitoring.
