| 20110064411 | METHOD FOR CONTROLLING THE CENTER WAVELENGTH OF AT LEAST ONE NARROW BAND OPTICAL CHANNEL WDM TRANSMITTING DEVICE IN A WDM NETWORK AND CORRESPONDING WDM TRANSMITTING DEVICE - The invention relates to a method for controlling the center wavelength of at least one narrow band WDM optical channel transmitting device in a WDM network. A reflected signal portion of a WDM channel signal is evaluated at the location of a WDM transmitting device. In order to generate the reflected signal portion, the optical multiplexing device or an additional reflective filter may be used, the additional filter revealing a low reflectivity at the desired channel center wavelength and a sharply increasing reflectivity adjacent thereto. The center wavelength of the WDM transmitting device is tuned to this target center wavelength by wavelength-modulating the center wavelength with a predetermined (low) modulation frequency and predetermined wavelength amplitude. The center wavelength of the WDM transmitting device is tuned such that the first order modulation frequency component of the reflected signal portion is minimized. In order to safeguard that the tuned center wavelength of the channel signal is actually within the passband of the respective WDM channel, the second order modulation frequency component may be monitored. Further, the invention relates to a WDM transmitting device and a WDM transmission network realizing this method. | 03-17-2011 |

| 20090087193 | Polarization mode dispersion compensation - Methods and systems for PMD compensation in an optical communication system are implemented by transmitting multiple optical signals through a common optical conduit to an optical compensator that adjustably rotates the polarization states of the multiple optical signals and transmits the rotated optical signals to an optical receiver. The receiver, upon sensing an excessive error condition, commands the optical compensator to change the polarization state of rotation, which changes the PMD profile of the received optical signals. | 04-02-2009 |
