During operation, the optical transceiver is greatly affected by temperature. If the operating temperature of the optical transceiver is too high or too low, the Tx power will generally decrease, the Receiver Sensitivity will decrease, and the eye diagram will deteriorate. In severe cases, errors in communication data will occur. If the temperature of the optical transceiver is not within the normal range, the switch will alarm, indicating that the optical transceiver is in a bad condition, and crucially, the switch will stop sending data until the optical transceiver returns to normal working conditions. Furthermore, abnormal temperatures may accelerate the aging of internal devices, reduce the life of the optical transceiver, and even directly cause damage to the optical transceiver. Therefore, it is imperative that the appropriate temperature level of the optical transceiver is selected according to the specific application environment, in order to avoid any potential issues.
Commercial grade temperature (0-70°C): used in data centers and enterprise computer rooms, where air conditioners are commonly installed to maintain room temperature.
Extended temperature (-20-85°C): designed for outdoor nodes in tropical areas, such as where higher ambient temperatures are common.
Industrial-grade temperature (-40-85°C): suitable for use in environments with large temperature changes, such as outdoors, remote mountainous areas, and tunnels. Industrial-grade optical transceivers import temperature compensation software that ensures a stable working current supply, so that when the temperature changes, the temperature compensation software takes effect.
In practical applications, commercial-grade and industrial-grade optical transceivers are more widely used.
Optical transceivers and communication equipment generate heat during operation. Selecting an optical transceiver with a suitable temperature level will ensure a low probability of a situation arising where the operating temperature of the optical transceiver is too low. In contrast, it is more common that the working temperature of the optical transceiver is too high. When the temperature of the optical transceiver exceeds the normal range, the indicator light of the corresponding port will turn red to indicate alarm. In such cases, the optical transceiver should be replaced, and after five minutes, the alarm status of the port indicator light should be monitored. If the red light of the port is off, this indicates that the optical transceiver has returned to normal operation.
Maintaining the temperature of the optical transceiver at a standard level is crucially important, and it is important to avoid purchasing low-quality or second-hand optical transceivers. Using inferior recycled materials or incorporating poor built-in designs may lead to poor heat dissipation resulting in frequent abnormal temperature fluctuations. To minimize the occurrence of abnormal temperatures in the optical transceiver, the specific application environment must be clearly defined when purchasing the optical transceiver, and the optical transceiver corresponding to the temperature level should be selected. It is also advisable to choose a reliable supplier to ensure the quality and performance of the optical transceiver.
When the temperature of the optical transceiver is too high or too low, the optical power will drop, the sensitivity will become lower, and the eye diagram will become worse. In severe cases, the communication data will be wrong. Be sure to clearly understand the specific application environment when purchasing an optical transceiver, and select one that corresponds to the appropriate temperature level. When the temperature of the optical transceiver exceeds the normal range, the indicator light of the corresponding port will turn red for an alarm. In such cases, the optical transceiver should be replaced, and after monitoring the port indicator light for five minutes, if the red light is off, this indicates that the optical transceiver has returned to normal operation.
