ABSTRACT:
A polarization scrambler comprising a multi-mode fiber spirally or preferably toroidally wrapped about a cylinder or toroid. The multi-mode fiber receives an optical signal from a long single-mode fiber. The optical output of the scrambler has an equal distribution of the two polarization states. Therefore, it can be passed through a polarization-sensitive filter or other optical device. The invention allows a low-cost receiver in a wavelength-division multiplexing communications system.
