Embodiment Construction
[0046] The laser transceiver device of the present invention, its manufacturing method and the method of increasing its temperature operating range will be further described in detail below in conjunction with the accompanying drawings and the embodiments of the present invention.
[0047] The basic idea of the present invention: the temperature of the pluggable integrated laser transceiver module such as SFP or SFP+ in the prior art is usually monitored by a temperature sensor mounted on the module circuit board. For a specific design of a transceiver module, there is usually a fixed temperature difference between the laser diode and the module circuit board. Therefore, the temperature of the laser diode can be determined by detecting the temperature of the module circuit board. If the temperature reported by the module is low, it means that the temperature of the emitting laser diode is also low. In this way, the microprocessor control unit (MCU) on the module can decide ...
