  • Polarization division multiplexing in optical data transmission systems
    Patent number: 6580535
    Abstract: Two optical signals of the same wavelength are polarization filtered at a sending end into orthogonal polarization orientations, and then added into a single optical transmission signal having various polarization components. The optical transmission signal is transmitted via an optical data link to a receiving end having a splitter. Portions of the optical transmission signal are inputted to different polarization filters logically corresponding to those at the sending end, to recover the two optical signals originally sent.
