摘要： An optoelectronic device uses microcode to perform an end of life calculation for the optoelectronic device. In a disclosed example, the optoelectronic device senses environmental and operational parameters under changing conditions during device operation. The optoelectronic device then calculates the end of life for itself based on one or more of the sensed environmental and/or operational parameters. The calculation can be done in real time and using digital logic. The calculation can provide a result in a format which is useful to a host system with which the device is connected. The optoelectronic device may automatically shut itself down upon reaching its calculated end of life.

摘要： A relatively small, pluggable optical transceiver utilizes a set of at least three separate printed wiring boards (PWBs), coupled together with a pair of flexible wiring boards, allows for the “middle” (base) PWB to be disposed in a horizontal plane, with the PWBs on either side (i.e., a transmitter PWB and a receiver PWB) to be disposed parallel to the base PWB, by virtue of using the flexible PWBs. Advantageously, the optoelectronic transmitter and receiver modules are directly connected (hardwired) to their respective, vertical PWBs, to form a rugged arrangement. Crosstalk between the vertical boards is reduced by using a shielding plate between the boards. Undesired fiber movement is reduced (as compared to the prior art) by separating the optical path from the electrical path, which also provides mechanical relief for the transmitter and receiver PWBs.
摘要翻译：相对较小的可插拔光收发器利用一组至少三个单独的印刷电路板（PWB），它们与一对柔性布线板耦合在一起，允许将“中间”（基板）PWB布置在水平面中，通过使用柔性PWB，两侧的PWB（即，发送器PWB和接收器PWB）平行于基板PW布置。有利地，光电发射器和接收器模块直接连接（硬连线）到它们各自的垂直PWB，以形成坚固的布置。通过在板之间使用屏蔽板来减小垂直板之间的串扰。通过将光路与电气路径分开，减少了不需要的光纤移动（与现有技术相比），这也为发射机和接收机PWB提供了机械释放。

摘要： Output optical power of an optical transmitter is regulated to compensate for fluctuations in output optical power and for tracking error. Dual loop automatic power control includes an optical sensor feedback loop for sensing optical energy proximate a back facet of the optical transmitter and a thermal sensor feedback loop for sensing thermal energy at point proximate the optical transmitter. Fluctuations in sensed thermal energy are indicative of the tracking error of the optical transmitter. Signals indicative of the sensed optical and thermal energy are combined and utilized to regulate the output optical power to be approximately constant over a predetermined range of temperatures.
