Claim 7:
8. A method for securing a fiber link, comprising:
coupling a plurality of optical signals into respective ones of a plurality of spatial paths of a spatially multiplexing optical fiber, wherein at least one of the plurality of optical signals is generated by an optically modulated transmit source to contain real data and wherein at least one of the plurality of optical signals is generated by at least one optically modulated chaff source as an optically modulated chaff signal;
wherein at least the optically modulated chaff signal occupies substantially a same optical frequency range as at least the optical signal that is generated by the optically modulated transmit source; and
wherein at least one of the at least one optically modulated chaff sources contains a data stream wherein the data stream is pre-recorded and stored at the chaff source.
