| 20080212977 | FIBER OPTIC TRANSMISSION LINES ON AN SOC - An optical transmission method. Signal transmissions between cores of an integrated circuit are performed. Each signal transmission is between two cores of a different pair of cores of the integrated circuit. Each signal transmission includes transmission of an optical signal in the visible or infrared portion of the electromagnetic spectrum at a wavelength that is specific to each different pair of cores and is a different wavelength for each different pair of cores. There is no overhead for decoding or arbitration in preforming the signal transmissions that would otherwise exist if a same wavelength for the optical signals were permitted for pairs of cores of the different pairs of cores. | 09-04-2008 |
| 20100209116 | OPTICAL TRANSMISSION SYSTEM, OPTICAL END TERMINAL EQUIPMENT, AND OPTICAL REPEATER EQUIPMENT - The present invention easily provides a network with high stability by setting a transmission rate without using a supervisory network in an optical repeater transmission system that uses multi-rate transponders. When setting a transmission rate of a multi-rate transponder, a rate changing data pattern is transmitted to a main signal to easily realize transmission rate setting for opposed equipment in an optical repeater transmission system through transmission and reception of the setting information. | 08-19-2010 |

| 20120020674 | STATUS LINK FOR MULTI-CHANNEL OPTICAL COMMUNICATION SYSTEMS - A robust and redundant status link is established by a first multi-channel optoelectronic device with a second multi-channel optoelectronic device in a multi-channel communication link. Transmitter bias currents are effectively modulated with a status link modulation signal representative of status data and subsequently modulated with primary data modulation signals. The resulting signals are transformed into optical signals and transmitted over the link as main communication links combined with a status link. At the second device, the optical signals are received and converted to electrical signals. The receipt of the optical signals creates multiple receiver bias currents, which may be monitored to detect the status link modulation signal. The second device may adjust various operating parameters in response to the information conveyed by the status link. For instance, devices can use status links to operate above nominal eye safety limits and/or to adjust transmit power to compensate for degradation effects. | 01-26-2012 |
