The working temperature of optical transceivers affects all the parameters of optical transceivers. If the ambient temperature of the optical transceiver changes, the operating current of the optical transceiver will vary with temperature. At the same time, the parameters of the optical transceivers change, which affects the normal transmission of optical transceivers. Today, we mainly talk about the causes of too high or too low temperature on optical transceivers and its impact.
What Is the Normal Temperature of Optical transceivers?
Because the type and brand of the optical transceiver are complicated, the temperature of modules corresponding to different optical transceiver temperature levels are different and the temperature specifications defined by the supplier are different, whether the temperature of optical transceivers is abnormal or not needs to be considered according to these factors. Before we use the optical transceiver, it is best to check the vendor’s definition of the temperature profile of the optical transceiver so as to reduce the number of problems caused by abnormal optical transceiver temperature.
Three Reasons That Affect the Temperature of Optical Transceivers
1. The Poor Quality and Workmanship
If you use the optical transceivers with poor quality and workmanship, then the phenomenon of abnormal temperature of the optical transceivers is more common. Because the function of such optical transceivers is instable, heat dissipation is also relatively poor. In order to reduce the temperature anomaly and unnecessary discard, we advise to use the optical transceivers with better function, quality and workmanship.
2. The Harsh Application Environment
Optical transceiver operating environment is in the data center, computer room or interchanger. If the optical transceivers are used in other environments, the change of the ambient temperature will inevitably change the temperature of the optical transceiver, thereby affecting its optical power and optical sensitivity. If the application environment of optical transceivers is harsh, then we advise to select the optical transceivers with industrial temperature or extended temperature.
3. The Use of Second-hand Optical Transceivers
The temperature of new optical transceivers is usually at 0-70 ° C and many second-hand optical transceivers are inaccessible. And the second-hand optical transceivers cannot operate normally in high-temperature or low-temperature conditions. Therefore, we advocate the use of new optical transceivers.
What Are the Impacts of High or Low Temperature on Optical transceivers?
If the optical transceiver temperature is too high or too low, it will affect the function of the optical transceiver and make the communication data appear faulty. The optical transceivers will alarm if its temperature isn’t in the normal range. If the optical transceivers are in a bad situation, interchangers will send data continuously. The optical transceivers will not send / receive data from the beginning until it is recovered to normal operation.
1. The Impact of Too High Temperature on Optical Transceivers:
If the operating temperature of optical transceivers is too high, the optical power of optical transceivers will become larger and the receiving signal will be faulty, and even the optical transceiver will be burned. As a result, the optical transceivers cannot work normally. In this case, DDM function should be added. You can select temperature control system for real-time monitoring and compensation to ensure that the optical transceiver extinction ratio and luminous power stable, to ensure the normal operation of the optical communication system.
2. The Impact of Too Low Temperature on Optical Transceivers:
Generally speaking, as long as optical transceivers are not exposed to the harsh environment below 0℃, the temperature will not be too low. It is better not to use the optical transceiver in the condition of too low temperature, as this may cause the function of the optical transceiver to be unstable.
