摘要： A translation circuit for mediating between a fiber-optic controller chip and a host device. The translation circuit may be on a fiber-optic transponder. The controller chip includes a phase locked loop that outputs a short synchronization signal when a hunting frequency passes through a target data signal frequency while hunting for a data signal and outputs a synchronization signal when the phase locked loop is locked onto a data signal. The translation circuit distinguishes between the synchronization signals and generates a lock signal when the phase locked loop is locked onto a data signal, but does not when the hunting frequency passes through the target data signal frequency. The lock signal may be used by a host device into which the fiber-optic transponder has been in installed. Errors from misinterpreted signals can thus be mitigated.

摘要： A general method is given for screening laser diodes for electrostatic discharge, (ESD), damage. The laser diode may be selectively isolated from the laser driver so that a current-voltage (I-V), curve can be taken and then compared to curves taken previously on the same laser diode to ascertain the possibility of ESD damage. Presumably the initial I-V curve will be representative of the characteristics of that particular laser in the undamaged state. Such an initial curve may be supplied by the manufacturer and may be a curve specific to a particular laser diode. Comparison with a standard curve is not sufficient to determine ESD damage in the early stages of failure. Some embodiments focus on isolating the laser diode from the laser driver, storing the information locally in the transceiver, and providing some analysis resulting in flagging laser diodes showing changes that are indicative of ESD damage.
摘要翻译：给出了用于屏蔽激光二极管静电放电（ESD），损坏的一般方法。激光二极管可以选择性地与激光驱动器隔离，使得可以采用电流 - 电压（I-V）曲线，然后将其与先前在同一激光二极管上获得的曲线进行比较，以确定ESD损坏的可能性。可能的是，初始的I-V曲线将代表在未损坏状态下该特定激光器的特性。这样的初始曲线可以由制造商提供，并且可以是特定于特定激光二极管的曲线。与标准曲线的比较不足以确定故障早期的ESD损伤。一些实施例集中于将激光二极管与激光驱动器隔离，将信息本地存储在收发器中，并提供一些分析，导致标记激光二极管，显示出表示ESD损坏的变化。

摘要： The principles of the present invention relate to aligning optical components with three degrees of translational freedom. A lens pin, a lens base, and a molded package are aligned in a first direction, a second direction, and a third direction such that the signal strength of optical signals transferred between a lens included in the lens pin and the molded package is optimized. The lens pin is mechanically coupled to the lens base to fix the position of the lens relative to the molded package in the first direction. Subsequently, the lens base and the molded package are realigned in the second and third directions such that the signal strength is again optimized. The lens base is mechanically coupled to the molded package to fix the position of the lens base relative to the molded package in the second and third directions.

摘要： An optoelectronic assembly includes an optoelectronic device, housed in a transistor outline (TO) package having a base and a signal lead traversing an aperture in the base, and a circuit interconnect coupled to the optoelectronic device and TO package. The circuit interconnect substantially comprises an insulator, and includes a data signal trace, a resistor, and a conductor. The data signal trace, on a first side of the insulator, transmits data signal current between the optoelectronic device and an external device. The resistor, also on the first side, transmits the data signal current between the optoelectronic device and the data signal trace. The resistor is electrically and mechanically connected to the signal lead and to data signal trace. The conductor, on a second side of the insulator, transmits a ground current between the TO package and the external device, and forms a current path substantially parallel to the data signal trace.
