In order to realize energy-efficient optical networks for future large bandwidth video transmission, we have proposed and demonstrated dynamic dispersion compensator called parametric tunable dispersion compensator (P-TDC). The P-TDC consists of a dispersive medium having frequency-dependent group velocity dispersion following a parametric frequency conversion. Utilizing four-wave mixing process in a highly-nonlinear fiber (HNLF) with a low dispersion slope for the frequency conversion, wideband operations of more than 1 THz and fast microsecond tuning responses have been demonstrated. This paper reports the development of a polarization-insensitive P-TDC based on a polarization diversity scheme with an optical loop configuration using a polarization-maintaining HNLF and 43-Gbit/s non-return-to-zero on-off-keying transmission with the P-TDC over 105-km field-installed fiber including JGN2plus testbed. The P-TDC achieves successful tunable optical dispersion compensation for more than 8 hours under the condition that the state of polarization of the received signal changes with time. Stable transmission of an uncompressed ultra-high-definition video, called Super Hi-Vision is also demonstrated. |
