Paper Abstract

We successfully generated 114-Gb/s PDM-8QAM optical signal by novel scheme. Intradyne coherent detection of PDM-8QAM optical signal with robust blind polarization de-multiplexing has been demonstrated by using a new cascaded multi-modulus equalization algorithm. With RZ-shaped PDM-8QAM modulation and the proposed blind polarization de-multiplexing algorithm, we demonstrate a record 33.9-Tb/s fiber capacity (320×114Gb/s) being transmitted over 580km of ultra-low-loss SMF-28 fiber utilizing C+L-band EDFA-only optical amplification and single-ended coherent detection technique, at a spectral efficiency of 4.2bit/s/Hz. Utilizing only C-band EDFA, we also demonstrate that 16.9-Tb/s capacity (160×114Gb/s)) can be transmitted over 640km of standard SMF-28 fiber.
