OFDR-KL9600 Demodulator
OFDR-KL9600 Distributed Optical Fiber Sensing System (Independently developed by Shanghai Kunlian Technology) This system employs a narrow-linewidth, highly stable frequency-swept laser source, combined with a high-dynamic-range interferometric receiver link and an adaptive Rayleigh scattering spectrum tracking algorithm. While maintaining extremely high spatial resolution, it significantly enhances the system's signal-to-noise ratio and measurement stability. Unlike the pulsed ranging mechanism of traditional OTDR-type systems, OFDR utilizes a frequency-modulated laser to generate phase encoding within the scanning range. By performing Fourier inversion on the spectral structure of the interference signal in the frequency domain, it obtains a Rayleigh scattering reflection profile along the length of the optical fiber.

Fundamental Principles of Fiber Optic Sensing Technology
Fiber Optic Sensing (FOS) refers to a class of detection technologies that utilize optical fibers both as a transmission medium and as the sensing element itself. By monitoring changes in the intensity, phase, polarization, frequency, or scattering characteristics of light propagating through the fiber, it enables precise measurement of physical parameters such as temperature, strain, pressure, vibration, acoustic waves, and displacement. Owing to its advantages—including immunity to electromagnetic interference, corrosion resistance, long‑distance transmission capability, lightweight design, and high sensitivity—fiber optic sensing has been widely adopted in fields such as energy, transportation, civil engineering, oil and gas, and safety monitoring.
