Abstract
A disclosed optical system comprises a repeater disposed between a first span and a second span of an optical cable and a node receiving an optical signal from the first span and transmitting a reflection to the first span. The node comprises a transmitter coupled to the first span to transmit the optical signal, transmit pulses having a test subcarrier and a tone, and provide a reference pulse; a receiver to receive the reference pulse and the reflection and passing a filter spectrum; and a DSP to: determine a first dispersion based on a first phase of the reference pulse and on a second phase of the reflection of a first pulse; determine a second dispersion based on a third phase of the reference pulse and a fourth phase of the reflection for a second pulse; and determine a first span seismic pressure based on the first and second dispersion.
