use 2 core digital telephone cable to realize ADSL Broadband access instead of using original parallel local cable.
ADSL is a technology based on twisted-pair cable transmission. so as to resist the external electromagnetic field disturb. we usually use parallel cable between junction box and user. It is bad for ADSL transmission. Overlong UTP transmission will cause instable connection, ADSL light flick, and affect surfing internet. While we can use twisted-pair cable instead parallel cable to solve the disturbing problem in surfing the internet, and meet the users’ requirements.
In addition, ADSL overly high frequency digital signal on the low-frequency voice of telephone cable. Although technically it will not affect the surfing speed, but the surfing speed lowed as connect unqualified equipment. We should not connect telephone or telephone security equipment before connect the filter in order to ensure the normal transmission of data. If permitted, to install one ADSL special line for avoiding many problems. It is best to install one line alone, such as 4 core or 2 core digital telephone.
some water-resist can easily absorb moisture, and affect the impedance and Attenuation, and return loss. So my company use a special protective film to cover the conductor appearance so as to avoid moisture. The structure from inner to outside is: conductor, insulation, special protective film and PE jacket. It greatly improve the quality of insulation wire, and lay a solid foundation for the latter products.
Major technical specifications
conductor:0.55mm solid bare copper wire Insulation:HDPE
shield layer:PEfilm jacket:PE insulation
attenuation:≤21.0(100MHz) return loss:15.1
DC resistance:≤8..44Ω/100m working temperature:-20°c-60°c
1.apply special material as protective film to avoid conductor affecting with damp,and ensure the signal transmission performance.
2.apply HDPE insulator as jacket to avoid moisture and corrosion,and extend the lifespan of the cable,the ageing resistance can meet the outdoor application,and the rigidity and hardness of the PE material making cable hard to break.
3.apply oxygen-free copper to ensure good stability.
