Summer is coming, and the weather begins to get very hot. People will suffer from heatstroke under high temperature. So is the optical module. If you don't want the optical module in the machine room hot enough to go wrong, please work with Xiaobian to find out how to avoid the high temperature of the light module.

1. Determine the operating temperature range of the optical module

The selection of optical modules needs to be based on the application scenarios, and the optical modules with different working temperature levels should be selected to avoid the optical modules from being used normally due to the harsh environment. Generally speaking, the enterprise network, data center and other network environments can use commercial optical modules, because the temperature of the indoor data center can be controlled, and the indoor machine room can be equipped with air conditioning and temperature and humidity controller to control the working environment temperature of the equipment in the machine room, so as to ensure that the actual application environment temperature of the optical module is within the acceptable temperature range of the optical module.

If it is used in industrial Ethernet and outdoor base station, the outdoor temperature is changeable due to the large working temperature range. In order to ensure the normal operation of the optical module, it is necessary to select the industrial optical module to avoid the problems such as receiving signal error and packet loss caused by excessive optical power dut to the high temperature of the optical module.

In addition, the incompatibility between the optical module and the equipment can easily lead to abnormal temperature. Before purchasing the optical module, it is necessary to fully understand the optical module information supported by the switch / optical fiber transceiver, such as data rate, model and transmission distance, so as to select the corresponding optical module to match the equipment.

For the purchase of optical modules, ETU-Link can supply three kinds of temperature, such as commercial 0 ~ 75 ℃, industrial - 40 ~ 85 ° C and expansion - 20 ~ 75 ° C. Before shipment, the high and low temperature aging test will be conducted to ensure the product quality.

Choose a good optical module, let you not only free from worry but also rest assured, choose ETU-Link is equal to choose to rest assured.

2. Check whether the heat dissipation condition of the optical module is qualified

① Check whether the heat dissipation equipment in the machine room operates normally. Air conditioning and temperature and humidity controller can effectively control the working environment of optical module within the applicable range.

② Select the plug-in device with good heat dissipation function. For example, the matched switch must have an air flow baffle and an open design on the front panel of the switch, etc., and have a good heat dissipation function device, so that the device temperature will not be too high due to long-term work, which will affect the temperature of the optical module.

ETU-Link can provide customized service for different application scenarios, including temperature customization of optical module. It can customize the optical module with commercial temperature range and industrial temperature range according to your needs. The optical module provided can support digital diagnosis function (DDM), which can effectively help users to monitor various parameters of optical module in real time, such as temperature, receiving sensitivity and optical power, etc.
