WXG-DAQ-1G has a built-in IQ demodulation function for balanced detector DAS systems, supporting both single-channel and dual-channel IQ demodulation. Meanwhile the upload rate can be configured as 1G, 500M, 250M, 125M, 83.33M, 62.5M, 50M and so on;
It supports three data upload modes: single-channel, dual-channel and four-channel. When using single-channel mode, the number of points per frame (the number of points captured by a single trigger pulse) can support a maximum of 262144 points, i.e., the length of a single optical fiber can reach a maximum of 262144*0.1m=26.2144 kilometers under the uploading rate of 1G (0.1m spatial resolution); if the uploading rate is lowered, it can support a longer optical fiber length.
