Classification: CPC H  G | IPC G  H

Claim 14:
15. A system comprising:
a first single mode fiber;
a first device connected to the first single mode fiber, the first device comprising:
an optical source arranged to generate a first optical signal; and
a polarization splitter-rotator arranged to rotate a polarization of the first optical signal to produce a source optical signal; and

a second device connected to the first single mode fiber, the second device comprising:
a signal processor arranged to generate a first data signal representing data received by the signal processor; and
a reflective modulator arranged to:
receive the source optical signal over the first single mode fiber;
modulate the source optical signal using the first data signal to produce a first modulated optical signal with a polarization that is orthogonal to a polarization of the source optical signal; and
communicate the first modulated optical signal to the polarization splitter-rotator over the first single mode fiber.
