After all, in some harsh environments, the general switch may not adapt very well. Therefore, in order to adapt to some special environments, industrial grade optical fiber switches play a role. What kind of environment is suitable for industrial optical fiber switches To understand the applicable scope of industrial optical fiber switch, you should know what kind of industrial optical fiber switch is and what kind of industrial optical fiber switch should be introduced!Industrial optical fiber switch is used in harsh environment, which can be known from its working temperature; The working temperature of industrial grade optical fiber switch is between - 40 ℃ - + 85 ℃, while its storage temperature is between - 40 ℃ - + 85 ℃, and its relative humidity is 5-95% (no condensation). This is between the characteristics of industrial optical fiber switch. It can be seen that its products are not suitable for general environment, so the application scope of industrial grade optical fiber switch is relatively targeted. For example, industrial grade optical fiber switch is used in tunnel! Ethernet standard stipulates that the maximum transmission distance is 100m, and data delay, packet loss and other phenomena may occur if it exceeds 100m. When the signals are transmitted in the twisted pair, they interfere with each other and are also
