Problems solved by technology
However, the gas discharge tube has the disadvantages of chronic gas leakage, short service life, slow discharge speed, high discharge temperature, and potential safety hazards
Although the solid discharge tube has long service life, fast discharge speed (about 1000 times that of the gas discharge tube), and low discharge temperature, the disadvantage of the solid discharge tube in the prior art is that the grounding capacitance is relatively large (about 60 times that of the gas discharge tube) , so it is difficult to meet the ground capacitance requirements of the security unit, which has an impact on ADSL / VDSL communication, especially for VDSL, because the use frequency of VDSL is an order of magnitude higher than that of ADSL, so compared with ADSL, the attenuation of VDSL is faster Bigger, worse transmission quality

Description
technical field [0001] The invention relates to the communication field, in particular to an integrated semiconductor discharge tube used for a security unit of VDSL communication. Background technique [0002] At present, optical fiber communication has been widely used. A security unit is usually installed between the fiber optic roadside and the user. The ground capacitance of this security unit is required to be less than 31PF, which is about one sixtieth of the voice security unit’s ground capacitance. Therefore, for such a small capacitance, it is difficult for the solid semiconductor discharge tube in the prior art to meet the requirements. [0003] Therefore, in order to meet the requirements of broadband communication, the already enabled gas discharge tube is re-applied in the security unit. The advantage of the gas discharge tube is that the ground capacitance is small, about 3PF. However, the gas discharge tube has the disadvantages of chronic gas leakage, shor...
