8b10b Line Coding of PSK Signals for Effective Homodyne Coherent Detection
Line Coding PSK Signals Homodyne Coherent Detection
2015/5/15
We demonstrate effective homodyne optical phase locking to a phase-shift-keying (PSK) signal with residual carrier by exploiting 8b10b coding. Low-penalty transmission over 215 km of installed dispers...
Intra-Channel Chromatic Dispersion Measurements with Live Neighboring Signals in a Long Haul DWDM System
Optical communications Networks wavelength routing Fiber measurement
2015/6/5
A novel four-tone probe signal is used to measure end-to-end residual chromatic dispersion in single 50-GHz DWDM channels of a long-haul ROADM network while transmitting more than 30 live signals in n...
