Narrow-pulse DAS integrated module with 3-meter spatial resolution

Product Introduction

This DAS integrated module is a DAS module capable of modulating and outputting narrow pulses; it can achieve a pulse width of 20ns, the measured spatial resolution reaches 3 meters, the monitoring distance is 10km, and the frequency signal is 80M. Therefore, it only needs to be paired with a 250M sampling rate acquisition card to work.

Product features
● The adjustable pulse width range is wide, enabling pulse width modulation from 20ns to 200ns.
● At a pulse width of 20ns, a spatial resolution of 3 meters can be achieved for a 10km optical cable.
● Even at a pulse width of 20ns, it can still be paired with a 250M acquisition card, offering high cost-effectiveness.

Application
● Scenarios with short distance and high spatial resolution
● Scenarios with high spatial resolution but sensitive to cost
