PRODUCT SYSTEM
Two lines — sensing instruments and acquisition cards — covering both DAS and BOTDA technology.
Portable and rack-mount instruments: the DAS acoustic sensing instrument reaches 110 km at 5.8 kg, while the BOTDA Brillouin analyzer reaches 104 km with ±1 °C and ±20 με accuracy. Fibre in, results out — no external optics to align.

ZC-DAS-002
ZC-DAS-002 is a high-speed acquisition and computing card dedicated to distributed fiber-optic vibration sensing: 500 MHz ADC at 14-bit, 1/2/4 channels, built-in pulse compression and frequency-diversity fading suppression, homodyne plus 80M/200M heterodyne demodulation, with fully domestically sourced core chips.
View specificationsWHY FBAK
Core acquisition boards, optical modules and portable instruments are all developed in-house — optics, demodulation and algorithms included.
Polarization, spatial and frequency diversity with pulse compression suppress coherent fading on long links, improving SNR and positioning accuracy.
Key devices and chips are domestically sourced, meeting China xinchuang procurement requirements with a self-controlled supply chain.
Up to 110 km on a single channel with 3–26 m spatial resolution — one unit covers an entire trunk pipeline or OPGW route.
