Effective homodyne optical phase locking to PSK signal by means of 8b10b line coding
TLDR
A novel technique is demonstrated that allows effective homodyne optical phase locking to a phase shift keying (PSK) signal with a residual carrier, with no penalty compared to back-to-back at a bit error ratio of 10(-3).Abstract:
We demonstrate a novel technique that allows effective homodyne optical phase locking to a phase shift keying (PSK) signal with a residual carrier. We exploit 8b10b coding of the signal in order to reduce its low frequency spectral content, suppressing the data-to-phase crosstalk effect. In a transmission experiment on a 10 Gb/s binary PSK signal (8 Gb/s before coding), we achieved transmission over 215 km of dispersion-compensated, installed single-mode fibre, with no penalty compared to back-to-back at a bit error ratio of 10−3. The proposed solution is applicable to other modulation formats, including multi-level amplitude and/or phase modulation formats.read more
