摘要	Embodiments of the present invention provide a system for increasing an operational life of a VCSEL. The system can include control circuitry for reducing an amount of bias current at high temperatures and increasing a power of the laser at low temperatures. This control circuitry can further include at least one of a temperature sensor, a Field Programmable Gate Array, a read only memory module, and an electrically erasable programmable read only memory module (EEPROM). In alternate embodiments, the control circuitry can further include a lookup table that sets the bias current depending on a temperature of the laser. The laser can be part of an optoelectronic transceiver module which can include, by way of example and not limitation, SFP, XFP, X2, XAUI, XENPAK, XPAK, GBIC, 8G, 16G, and other optoelectronic modules.
其他摘要	本发明的实施例提供了一种用于增加VCSEL的使用寿命的系统。该系统可以包括控制电路，用于减少高温下的偏置电流量并在低温下增加激光器的功率。该控制电路还可以包括温度传感器，现场可编程门阵列，只读存储器模块和电可擦除可编程只读存储器模块（EEPROM）中的至少一个。在备选实施例中，控制电路还可以包括查找表，该查找表根据激光器的温度设置偏置电流。激光器可以是光电收发器模块的一部分，作为示例而非限制，其可以包括SFP，XFP，X2，XAUI，XENPAK，XPAK，GBIC，8G，16G和其他光电模块。
