Disclosed are techniques for time-interleaved phase-OTDR (ϕ-OTDR) with nested phase references that advantageously enables faster synchronization times. Our inventive techniques employ nested phase references which enables faster phase synchronization in time-interleaved ϕ-OTDR by transmitting a plurality of phase reference channels alongside the frequency-division multiplexed (FDM) channels. Compared with prior art in, more than one reference channel is used to achieve faster phase synchronization at the cost of higher bandwidth and system complexity.
