Use of higher order modulation techniques to transmit information on passbands of a dispersion-limited fiber link |
摘要 |
Systems and methods employing higher order modulation techniques to transmit information on passbands of a dispersion-limited fiber optic communication link. The present invention transmits data on previously unused passbands of the dispersion-limited optic link, thus increasing the total capacity of the link. Higher order modulated carrier frequencies (M-ary ASK, PSK, QAM, etc.) centered within the higher passbands are transmitted using the present invention. Thus, the present invention combines a multiplicity of encoded carriers into a composite microwave spectrum that is tailored to the passbands of the optical link.
