     ShenZhen Speed Technology Co., Ltd, founded in 2004, is a high-tech enterprise which specializes in the manufacture of professional and reliable network equipment, undergoing its own research,development,manufacturing and selling & after sales services.
     At present, Speed Technology products are widely used in telecommunication, broadcasting, community access, monitor and other industries, recognized by many customer in a variety of LAN constructions such as enterprises, hospitals, schools, internet cafes and so on.
     In 2005, firstly introduced the full Gigabit switches with 24 eletricity ports and 2 optical ports, laid a good foundation of development of "fiber backbone".
     In 2008, firstly manufactured the second layer gigabit switches with optical ports, became the pioneer of promoting gigabit fiber network, and successfully introduced the fiber backbone solutions of LAN with higher cost-effective and stable performance, for the coming of gigabit fiber era wrote a great deal!
     In 2012, firstly introduced full 10GE fiber backbone switch, leading the era of the local "full 10Gb fiber backbone" ! And laid a good foundation of development of "10G fiber" times.
