Zhongxin Optoelectronics Unveils First‑Cost‑Effective FBG Demodulator & Scanning Module

As a top‑tier supplier of tunable laser chips, Shandong Zhongxin Optoelectronics Technology Company has newly launched the world’s first budget‑friendly fiber‑Bragg‑grating (FBG) demodulator and scanning module.

Both devices adopt self‑developed C‑band 8‑10 nm narrow‑band DBR tunable laser chips. The in‑house‑manufactured core optical components realize domestic‑grade supply for FBG sensor systems and bring outstanding cost‑performance to end‑users.

A fast scanning‑and‑demodulation rate up to 200 Hz is supported for the two hardware units. Custom‑configurable specifications cover an 8‑10 nm C‑band scanning range and optical‑channel options from 1 to 32 channels. Outstanding strengths contain precise wavelength readouts, stable optical‑power output and rapid scanning speed.

The devices serve as the core hardware of FBG‑based sensing systems for real‑time physical‑parameter measurement, including strain, temperature, displacement, vibration and structural deformation.

Their monitoring capability covers multiple critical‑industry scenarios. Structural‑safety early‑warning is available for bridges, tunnels and large‑scale buildings. The equipment safeguards production safety for wind‑power farms, power‑transmission networks, coal mines and petroleum plants. Besides, it delivers operational monitoring for high‑speed railways, highways and rail‑transit infrastructures.
