Measured distribution map of Brillouin gain spectrum (BGS) along a fiber under test with dual-laser BOCDR

Caption

The figure shows the Brillouin-gain-spectrum map obtained along a 13-m single-mode silica fiber. The upper diagram marks a ~1.1-m strained section. The lower color plot displays the corresponding shift in Brillouin frequency, confirming distributed strain sensing.
