Patent number: 8882366Abstract: Chip identification pads for identification of integrated circuits in an assembly. In one example embodiment, an integrated circuit (IC) assembly includes a controller, a plurality of ICs, a shared communication bus connecting the controller to the plurality of ICs and configured to enable communication between the controller and each of the plurality of ICs, and a set of one or more chip identification pads formed on each IC.

Patent number: 8687969Abstract: Two or more optical transceivers coupled to each other by an optical link to optimize communication over the optical link. A first transceiver generates electrical data that represents an operational parameter for optimization. The transceiver then converts the electrical data into an optical signal and transmits the optical signal over the optical link to a second transceiver. The second transceiver recovers the electrical data from the optical signal and uses the recovered electrical data to change characteristics of the optical signal transmitted by the second transceiver.Type: GrantFiled: October 4, 2010Date of Patent: April 1, 2014Assignee: Finisar CorporationInventors: Luke M.

Patent number: 8583395Abstract: Systems and methods for an optical transceiver module to perform one or more diagnostic self-tests without the assistance of a host computing system. The optical transceiver module includes at least one processor, a persistent memory and a system memory. The persistent memory, which is coupled to the at least one processor, contains microcode. The microcode is loaded from the persistent memory to the system memory and executed by the at least one processor. The executed microcode causes the optical transceiver module to perform one or more diagnostic self-tests. The diagnostic result data of the one or more diagnostic self-tests is then stored in the persistent memory and is formatted for analysis. The formatted data may then be analyzed to ascertain the response of the optical transceiver to changes in its test environment.Type: GrantFiled: July 23, 2007Date of Patent: November 12, 2013Assignee: Finisar CorporationInventors: Gerald L.

Patent number: 8290365Abstract: An optical communication apparatus that includes multiple optically communicative components positioned optically in series. Some of the optically communicative components may be optical fiber segments of perhaps different types. The optical channel represented by the series of optically communicative components and approximates a transfer function of an optical channel of a longer optical fiber. Accordingly, rather than deal with a lengthy optical fiber, an apparatus having a shorter optical channel may be used instead. The construction of the optical communicative components may be calculating an input transfer function. The construction would include an ordering of discrete optically communicative components that, when placed optically in series, simulates an estimation of a particular transfer function. Testing may then occur by actually passing an optical signal through the series construction of optically communicative components, rather than through the longer optical fiber.Type: GrantFiled: August 20, 2008Date of Patent: October 16, 2012Assignee: Finisar CorporationInventors: Gayle L.

Patent number: 7974538Abstract: An environment that facilitates the purchasing and updating of specific operational features in an optical transceiver (or optical transmitter or optical receiver). The environment includes a host computing system (hereinafter referred to as the “host”), a network, a remote computing site, and an optical transceiver having a system memory and at least one processor. The host determines that microcode that governs the behavior of an optical transceiver is desired to be purchased. A request to purchase the microcode is sent over the network from the host to the remote computing site. The remote computing site responds to this request by providing the host information by which the purchased microcode may be accessed. The host may then access the microcode. Finally, the host provides the microcode to the optical transceiver memory where it may later be executed by the processor.Type: GrantFiled: October 21, 2005Date of Patent: July 5, 2011Assignee: Finisar CorporationInventors: Jayne C.
