摘要： A loss of signal assert and de-assert level programming mechanism in an optical transceiver coupled to a host computing system. A control module is connected to the host so as to receive the programmable loss of signal level. A post-amplifier detects when the receive power drops below a loss of signal level. However, in this case, instead of the loss of signal level being static, a loss of signal level adjustment mechanism changes the loss of signal level detected by the post-amplifier as directed by the programmable loss of signal level received from the host. The loss of signal assert and de-assert levels may be calibrated by comparing receive power to the threshold for assertion and de-assertion of the loss of signal.

摘要： The optoelectronic transceiver includes first and second controller ICs. Each controller IC includes logic, a memory, an interface, and at least one input port. Each memory is configured to store digital diagnostic data and has a unique serial device address to allow a host access to each of these controller ICs separately and independently. At least some of the digital diagnostic data is common to both the first controller IC and the second controller IC. The inclusion of two controller ICs allows the same diagnostic data to be stored in completely different memory mapped locations. This allows hosts that are preconfigured differently to read different memory mapped locations on the different controller ICs to obtain the same diagnostic data.

摘要： A system for holding a device in a computer system, the computer system including a drive cage for holding the device, is disclosed. The system comprises a first rail coupled to one side of the device and adapted to fit into the drive cage and a second rail coupled to the device at a side opposite the one side and adapted to fit into the drive cage, wherein the first and second rails are coupled to the device without requiring a tool. Computer systems utilizing the system in accordance with the present invention, will be better equipped to handle the acoustic vibrations created during the operation of different types of drives such as Direct Access and Storage Devices (DASDs). Accordingly, this will enable computer system manufacturers to incorporate faster DASDs without acoustically coupling the DASD to the chassis. Furthermore, by employing a screw-less rail, PC manufacturers and users will no longer be required to use a tool to remove the attached rails. This facilitates the easy removal and reinstallation of DASDs when interchanging computer components.

摘要： A cooling apparatus, method and article of manufacture are disclosed which provide for selectively providing power to an attached heat-dissipating apparatus having a cooling probe in thermal contact with a cooling unit, to remove heat generated by a heat-generating source within the computer to an external environment outside of the computer. Power may be conserved, portable battery life extended, higher-speed processors utilized, and overall dimensional characteristics of a personal computer may be slimmed and reduced by utilizing the apparatus with a personal computer. Heat energy is transferred across a thermal connection interface from the heat-generating source of the personal computer to a collection face of the apparatus, and thereafter collected heat energy is dissipated in relation to the available power of the power source and/or the planned operating speed of the processor.

摘要： A microprocessor is used to control the temperature of a laser emitter and thereby regulate the wavelength of optical signals from the laser. A serial interface in the microprocessor provides input and output lines to a host device, and temperature lookup tables are stored in nonvolatile memory. Control logic processes information stored in the memory as well as information on operating conditions of the laser emitter to precisely control the temperature of the laser emitter. A thermo-electric cooler adjusts the temperature of the laser emitter.

摘要： A method for compensating for wavelength drift in a fiber-optic laser transmitter includes 1) controlling a temperature within the optoelectronic assembly at a defined level; 2) driving the optoelectronic assembly to emit light, wherein the emitted light has a wavelength that is within a channel of operation, the channel of operation including a range of wavelengths centered around a channel center wavelength; 3) accessing from memory within the optoelectronic assembly a control value associated with the temperature of the optoelectronic assembly at defined points within an operational lifetime of the optoelectronic assembly; and 4) recalculating the defined level by reference to the control value, whereby a wavelength of the optoelectronic assembly is maintained within the channel of operation despite an expected drift of wavelength.
