length of 1.5m. It is an RG8 coaxial cable with N-type connector as the antenna feeder.
Signal Surge Protective
Figure 31: Signal Surge Protective Device
This surge protective device is suitable to Category 6 cable or Class E cable for protection of equipment from
surge and over-voltage induced by lightning or produced in the inner systems. It is widely used in office and
industry comprehensive network wiring projects or the similar telecommunication applications, such as Gigabit
Ethernet, ATM, ISDN and VoIP systems.
High performance chips with smallest parasitic capacitance are adopted in the product, all line protection for the 8
lines, fast response, giving it a ideal choice for protection of lightning effect.
Multiple stage protection structure provides good protection of lightning effect, the tolerable lightning impulse
current is 10 kA(between 8 lines in total to the PE ), the product complies with the related international and
domestic standards.
