SYV aluminum foil shielded and copper braided shielded coaxial cable manufacturers tell you that coaxial cables can be divided into two basic types, baseband coaxial cables and broadband coaxial cables.

1. Baseband coaxial cable
The shielding layer of the baseband coaxial cable is usually a mesh structure made of copper, and its characteristic impedance is 50Ω. SYV aluminum foil shielded and copper braided shielded coaxial cable manufacturers tell you that this cable is used to transmit digital signals, and the commonly used models are RG-8 (thick cable) and RG-58 (thin cable). The most intuitive difference between thick and thin cables is the diameter of the cables. Thick cable is suitable for relatively large local network, its standard distance is long and reliability is high; but thick cable network must be installed with transceivers and transceiver cables, and the installation is also difficult, so the overall cost is high. On the contrary, the thin cable is relatively simple and the cost is lower; the manufacturer of SYV aluminum foil shielded and copper braided shielded coaxial cable tells you that because the cable needs to be cut off during the installation process, it is easy to cause poor contact when there are many joints.
SYV aluminum foil shielded and copper braided shielded coaxial cable manufacturers tell you that whether it is a network connected by thick or thin cables, the fault point often affects all machines on the entire cable, and it is very troublesome to diagnose and repair the fault. Therefore, baseband coaxial cables have been gradually replaced by unshielded twisted pair or fiber optic cables.
2. Broadband coaxial cable
Broadband coaxial cable shields are usually stamped from aluminum and have a characteristic impedance of 75Ω. This kind of cable is usually used to transmit analog signals, and the commonly used model is RG-59, which is a standard transmission cable used in cable TV networks, and can transmit multiple TV signals simultaneously in one cable. SYV aluminum foil shielded and copper braided shielded coaxial cable manufacturers tell you that broadband coaxial cables can also be used as transmission media for some computer networks.
