According to the location where the coaxial cable is applied, it can be roughly divided into 3 types.
1. Trunk cable: generally thick cables with an outer diameter of insulation of more than 9mm, requiring low loss and low flexibility.
2. Branch cables: medium and thick cables whose insulation outer diameter is generally more than 7mm, require low loss and certain flexibility.
3. User distribution network cable: its insulation outer diameter is generally 5mm, and the loss requirement is not important, but good flexibility and indoor uniformity are required.
