In the recent days,Huafei Tech industrial switches through 9KM elevation low pressure test by The 702 Research Institute,The first Research Academy of China Aerospace Science and Technology Corporation.The test proves highly adaptable capacity of our Industrial Switches work under low pressure. Additional,our industrial switches tested standard performance A of electrostatic discharge interference far more than standard B,and achieve zero packet loss. Moreover, Huafei Tech Industrial Swiches being implemented difficulty of damp heat test and passed the test of high and low temperature are better than standard temperature -30~70℃,smoothly through test of -40~85℃.All of these can been seen high safety in harsh environment of Huafei Tech Industrial Switches 

Till now,Beijing Hufei Tech has successively passed authority tests such like the Ministry of public security, Ministry of communications, Ministry of railways, the Ministry of national electronic computer equipment testing center ect.Via this test,it future affirmed reliability of Beijing Huafei Tech Industrial Switches could be used in various fields.

At present, China has successively passed and othe authority, the Ministry of aerospace testing, and further affirmed the reliability of China's flying industrial exchange in various fields.

More than 6000units optical transmission equipment will be used in Qingdao Railway
