APPLICATION

>> Application Background:        
1 Climate warming, the thunderstorm weather increased           
2 VDSL is a kind of asymmetric DSL technology.           
3 In a pair of copper wire to support upstream rate to 1.5Mbps ~ 2.3Mbps, downstream rate to 13Mbps ~ 52Mbps           
4 Effective transmission range in the range of 1.2 ~ 0 km           


>> Program description and notes:           
1 A large flow, small size of GDT  is used at the front end of the transformer   
2 A small junction capacitance, small size of TVS is used at the back end of the transformer         
3 GDT height is not more than 2mm, and can be welded on the back of PCB board.           
4 To meet the IEC61000-4-5, GBT17626.5, K21, K20, GR1089 and other surge test standards.           


>> Application:           
1 Switch           
2 PON           
3 Home gateway         

4 Router
