    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.

    摘要: One example of a method for operating a transceiver includes selecting a first operating wavelength from a set of operating wavelengths. Next, a first control value is accessed that corresponds to the first operating wavelength. The first control value also corresponds to a first operating temperature of the transceiver, and the first operating temperature resides within a range of about 30° C. to about 50° C. Finally, the transceiver is operated substantially at the first operating temperature.

    摘要: A system and method for testing the jitter tolerance and signal attenuation tolerance of an optoelectronic device is disclosed. The system includes a generation circuit, delay circuit and comparison circuitry. A first sequence of bits is generated, delayed, and sent to the optoelectronic device. The optoelectronic device receives the bits and retransmits them as a second sequence to the comparison circuitry, which compares the two bit sequences to determine a bit error rate. The bit error rate is then used to determine the jitter tolerance and, in an alternate embodiment, the signal attenuation tolerance of the optoelectronic device being tested.

    摘要: Exemplary embodiments of the present invention selectively adapt the pad architecture on bi-directional opto-electronic transceiver modules to connect to legacy unidirectional ports, panels and the like. This allows the bi-directional module to function correctly when connected to either a unidirectional or a bi-directional port. Conversely, exemplary embodiments also selectively adapt the pad architecture on bi-directional patch panels or ports to connect to legacy unidirectional optoelectronic transceiver modules. This allows the port to function correctly when either a bi-directional or a unidirectional transceiver is connected to it.

    摘要: A method of protecting a glass substrate, especially a display glass or a hard disk blank made from a glass or a glass-ceramic, from unacceptable surface damage and scratches, often leading to glass breakage, during processing and transport, is described. This protective method includes applying a removable protective coating made of at least one polymer layer, or at least one polyvinyl alcohol layer, to the glass substrates by spraying or rolling the polyvinyl alcohol or a polymer solution of the polymer to be applied in a polar organic solvent, onto the glass substrate, or dipping the substrate into it. Then when the substrate is ready for its end use, the protective coating is removed by washing in water or polar organic solution so that a residue does not remain on it. The glass substrates, protected in this manner have outstanding surface quality and improved hard disk blanks can be economically produced from them.

The plug connector has a low maximum cross-sectional area and a high tightness. The plug connector has a housing (1) partly forming a cone (11), a hollow cylinder (12) which is molded onto the cone (11) on the side facing away from the plug and has an external thread (121), a nut (5) screwed onto the hollow cylinder (12), and a sealing element (4) which completely fills the hollow cylinder (12) and the nut (5). A four-way cable (3) penetrates the nut (5) and the sealing element (4) in the axial direction. A groove (14) is arranged on the side of the housing (1) facing toward the plug to accommodate a seal (6) and a ring (15) is molded on the cone (11) on the side facing toward the plug and encloses the plug coaxially at the end. A contact insert (2) is arranged in the housing (1), in which four flat contact clamps, to which the ways of the cable (3) are connected, are arranged in a countersunk fashion. The contact insert has a central axial hole (27) in which a screw (7) for securing the plug connector on the plug is captively arranged, and which is fixed nonrotably in the housing (1) by a bayonet closure and a locking tab (17) arranged in the housing (1) and can be detached only by a tool.
