Sometimes used for the same thing, sometimes not.

Generally a fabric would be something mentioned with switches as it provides a paths between ports that are not shared.  If you had ports A,B,C and D.  A and C could "converse" while B and D also "converse", but without any bandwidth contention.

Generally a backplane is the what you plug cards into and is part of the "empty" chassis; it may have a fabric architecture or a bus architecture (or some combination).
