As a sales of Optical Transceiver Modules should know that the working temperature will influence the parameters of the optical transceiver. When the applied environment temperature of the module is changed, then the working current will change as the temperature changes. At the same time, it will lead to changes in the parameters of the optical transceiver.Thus affecting the normal transmission o...
