1. Data signal propagation in an optical network equipment for increased reliability, comprising:

  • a first data signal embodied in a first optical signal on a first optical path in the optical network equipment;

    the first data signal simultaneously embodied in a second optical signal on a second optical path in the optical network equipment;

    wherein the first optical path is different from the second optical path;

    wherein if the first optical path should fail then the second optical signal on the second optical path can provide continued first data signal propagation in the optical network equipment, or if the second optical path should fail then the first optical signal on the first optical path can provide continued first data signal propagation in the optical network equipment.
