ABSTRACT:
Sagnac interferometer based secure communications systems are integrated into high speed data transfer rate networks using a smaller number of separate fiber optic cables than would be required if networks were constructed from pluralities of point-to-point systems. Redundancy can be provided in the networks to enable the network to operate even if multiple failures occur in the network.
