摘要： The present invention provides a host board system (2) in which transceivers (60−1) of two sizes (the larger approximately twice the width of the smaller) can be arbitrarily mixed within a given host board design. This is accomplished by specifying an arrangement of electrical connectors (90), a guide rail design (110) , a set of transceiver features, and a bezel (20) configuration to meet this need as well as the other requirements of optoelectronic transceivers. Typically, two slots (80) and connectors (90) are lined up behind an opening (30) in a bezel (20) that provides transceiver access (70) to two connectors (90). So that either double−width or single−width transceivers (60, 70) can be used in the same opening (30), the double−width transceiver (60) is designed to engage with the connectors (90) in the same position as a single−width transceiver (70). Further, the slots (80) and connectors (90) are spaced evenly so that all of the slots (80) and connectors (90) can accommodate a single−width transceiver (70) and all adjacent slots (80) and connectors (90) can accommodate a double−width transceiver (60).

摘要： An optical transceiver is disclosed. The transceiver includes a receiver having adaptive electronic dispersion compensation (EDC) circuitry on at least one optical channel. The adaptive electronic dispersion compensation circuitry provides diagnostics information to a host system. The transceiver can be an XFP, X2, XENPAK, SFP, SFF, GBIC or other type of transceiver. The diagnostics information can include information on the time variation of a quality of the optical channel and/or a measure of a worst state of the optical channel over a period of time. The diagnostics information can also be derived from a measure of a quality of an equalized receiver signal, a current tap weight value, and many other specific values.

摘要： The optical transceiver module includes an optical transmitter and an optical receiver. The optical transceiver module also includes an internal serial bus and a plurality of addressable components electrically coupled to the internal serial bus. Each of the addressable components included a serial interface for communicating with the internal serial bus, and a memory. Each addressable component also includes a unique address or chip select logic coupled to a controller via a chip select line. This allows data to be addressed to specific addressable components. The addressable components may include a laser driver, a laser bias controller, a power controller, a pre-amplifier, a post-amplifier, a laser wavelength controller, a main controller, a electrothermal cooler, an analog-to-digital converter, a digital-to-analog converter, an APD bias controller, or any combination of the aforementioned components.

摘要： A controller (110) for controlling a transceiver having a laser transmitter and a photodiode receiver. The controller includes memory (120, 122, 128) for storing information related to the transceiver, and analog to digital conversion circuitry (127) for receiving a plurality of analog signals from the laser transmitter and photodiode receiver, converting the received analog signals into digital values, and storing the digital values in predefined locations within the memory. Comparison logic (131) compares one or more of these digital values with limit values, generates flag values based on the comparisons, and stores the flag values in predefined locations within the memory. Control circuitry (123-1, 123-2) in the controller controls the operation of the laser transmitter in accordance with one or more values stored in the memory. A serial interface (121) is provided to enable a host device to read from and write to locations within the memory. Excluding a small number of binary input and output signals, all control and monitoring functions of the transceiver are mapped to unique memory mapped locations within the controller. A plurality of the control functions and a plurality of the monitoring functions of the controller are exercised by a host computer by accessing corresponding memory mapped locations within the controller.
