Abstract
A method for securing communication over an optical fiber, comprising: supplying an optically modulated version of a desired sequence of information that is intended to be transferred over a multicore optical fiber to a first core of the multicore optical fiber; and supplying an unmodulated optical chaff signal to a second core of the multicore optical fiber that is spatially distinct from the first core; wherein the fiber is adapted to transport the optical chaff signal from a first end thereof to a second end thereof unmodified in the second core; and wherein the fiber is adapted to transport the optically modulated version of a desired sequence of information from the first end of the fiber to the second end of the fiber unmodified in the first core and independent of the chaff signal in the second core unless there is a tap of the fiber.
