ABSTRACT:
An optical fiber having a square or rectangular cross section provides one mode of optical signal transmission comprising reflection between one pair of parallel sides and a second mode between a second pair of parallel sides perpendicular to the first pair so that two separate channels are obtained in a single optical fiber. A transmitter and a receiver are coupled to each end of the optical fiber so that full time two-way communication can occur without substantial interference.
