Paper Abstract

A fiber accelerometer array is presented with an unprecedented breakthrough combination of high acceleration resolution after 100 km of fiber, in a bandwidth down to the infrasonic, with high multiplexing density and low crosstalk. The demonstrated resolution is better than 60 ng/√Hz for all channels down to 10 Hz, even after the 100 km length of fiber. Moreover, the system can accommodate 80 channels per fiber in wavelength division multiplexed operation with better than -64 dB crosstalk. The dynamic range is 120 dB in a 300 Hz bandwidth.
