| 20090087187 | Method for Transmitting Optically Transmitted Data Via a Radio Antenna and Corresponding Device - In a method a carrier signal is modulated depending on data to be transmitted. The modulated carrier signal is transmitted via an optical fiber line. The transmitted modulated carrier signal is demodulated, thereby producing received data. The transmitted modulated carrier signal is used to produce an auxiliary carrier signal. Said auxiliary carrier signal is modulated depending on the received data and then transmitted via a radio antenna. | 04-02-2009 |

| 20090238564 | PROTECTION DEVICE FOR REMOVING SIGNAL INTERFERENCE IN A PASSIVE OPTICAL NETWORK - The invention relates to a protection device for removing signal interference in a passive optical network, in which a central optical cable ( | 09-24-2009 |
| 20100254714 | DATA TRANSMISSION WITH ROOM ILLUMINATIONS HAVING LIGHT EMITTING DIODES - Lamps having light emitting diodes configured for data transmission require the high-frequency circuit of higher power. In order to simplify the required electronics, the light emitting diodes are divided into groups and the groups are modulated differently. Due to the multilevel modulation, the symbol rate can be reduced with the data rate remaining the same, thus reducing the switching rate and the circuitry complexity. | 10-07-2010 |
| 20110044687 | METHOD AND DEVICE FOR DATA PROCESSING IN AN OPTICAL NETWORK AND COMMUNICATION SYSTEM - A method and a device process data in an optical network. At least one dedicated time slot is used for transmitting time critical information from an optical network unit towards an optical line terminal. Due to the dedicated time slot, previous long delays in channel switching are decreased or substantially avoided. | 02-24-2011 |
| 20110076033 | COHERENT OPTICAL SYSTEM COMPRISING A TUNABLE LOCAL OSCILLATOR - A method and an optical network component for data processing in an optical network. A first signal and a second signal are influenced by a tunable element. The first signal is an incoming optical signal, and the second signal is a local oscillator signal generated by a laser. The laser has an optical gain element that is tuned by the tunable element. A communication system is provided with the optical network component. | 03-31-2011 |
| 20110182584 | METHOD FOR DATA PROCESSING IN AN OPTICAL NETWORK, OPTICAL NETWORK COMPONENT AND COMMUNICATION SYSTEM - A method for data processing in an optical network includes providing several main wavelengths and processing a subcarrier modulation for the several main wavelengths. An optical network component and a communication system including such an optical network component are also provided. | 07-28-2011 |
| 20120014690 | METHOD TO DEFINE SHARED RISK LINK GROUPS IN OPTICAL TRANSPORT SYSTEMS - A method defines shared risk link groups in optical transport systems, in which two optical links sharing at least one single point of failure are considered to be non-disjoint. For each optical link there is measured and recorded a polarization state characteristic and two links having the same characteristic are judged to be non-disjoint and to be in the same shared risk link group. | 01-19-2012 |
