摘要： The present invention relates to an apparatus for controlling temperature of an optical module using an uncooled laser diode. A first setup unit for establishing low-temperature setup voltage and a second setup unit for establishing high-temperature setup voltage determine first and second threshold voltages suitable for low-temperature and high-temperature setup voltages, respectively. First and second comparators compare the low-temperature and high-temperature setup voltages with sensor voltage received from a sensor voltage entry unit, respectively. The output signals of the comparators are applied to a logic circuit, such that the logic circuit generates on/off signals according to the result of the comparison. The logic circuit generates a high-level signal only when the sensor voltage escaped from a predetermined voltage range, and thus operates the temperature control circuit. Therefore, the TEC and the heater contained in the TEC/heater mounting member are operated to generate heat, such that the uncooled laser diode can be heated or cooled at only predetermined temperature. As a result, the uncooled laser diode can be heated or cooled at only predetermined temperature, controls temperature of the optical module at a low power level, resulting in reduction of power consumption.
摘要翻译：本发明涉及一种使用非制冷激光二极管控制光学模块的温度的装置。用于建立低温设置电压的第一设置单元和用于建立高温设置电压的第二设置单元分别确定适合于低温和高温设置电压的第一和第二阈值电压。第一和第二比较器分别将低温和高温设置电压与传感器电压输入单元接收的传感器电压进行比较。比较器的输出信号被施加到逻辑电路，使得逻辑电路根据比较结果产生开/关信号。只有当传感器电压从预定的电压范围逃逸时，逻辑电路才产生高电平信号，从而操作温度控制电路。因此，TEC /加热器安装部件中包含的TEC和加热器被操作以产生热量，使得非冷却的激光二极管可以仅在预定温度下被加热或冷却。结果，非冷却的激光二极管可以仅在预定温度下被加热或冷却，从而将光模块的温度控制在低功率水平，导致功耗的降低。

摘要： A latch type optical communication module, designed to9 be easily mounted and detached to a system port having a cage by means of a latch. The optical communication module is provided with a latch: The latch may be rotated around a hinge shaft fixed to both sides of a receptacle while being inserted into latch holes penetrating both ends of the latch. When the latch is rotated and then allows latch drivers to force a slider upward, the slider raises a fixing tap of the optical communication module inserted into the system port, thereby allowing the optical communication module to be detached from the system port. With the construction of the optical communication module, the plurality of additional components are not required for the optical communication module, thereby lowering manufacturing costs, and the optical communication module can be detached from the system port without any tool and any influence against adjacent optical communication module.

摘要： An optical communication module is provided with a platform to provide an accurate axial alignment with optical transceiving subassemblies. In the optical communication module, axes of the optical transceiving sub-assemblies are aligned by virtue of previously established axial alignment of the platform, and the platform is fixed to a main body by inserting an insertion jaw of a cover into an insertion groove formed on an upper surface of the platform. After the optical transceiving subassemblies are inserted into the platform having the axial alignment required for a system, a bonding agent is filled into spaces defined in the platform, thereby preventing the axes from deviated by an external force. The optical communication module allows for easier and more accurate guidance of a connection between the optical transceiving sub-assemblies and the optical connector, thereby minimizing the optical loss, and preventing the patterns on the printed circuit board from being damaged due to the insertion and disconnection of the optical connector.
