SYV aluminum foil shielded and copper braided shielded coaxial cable supplier tells you that coaxial cable can be divided into two basic types, baseband coaxial cable and broadband coaxial cable. The supplier of SYV aluminum foil shielded and copper braided shielded coaxial cable tells you that the baseband is a commonly used cable at present, and its shielded wire is a mesh made of copper with a characteristic impedance of 50; the shielding layer of the cable commonly used for broadband coaxial cables is usually It is stamped from aluminum and has a characteristic impedance of 75.

Coaxial cables can be divided into thick coaxial cables and thin coaxial cables according to their diameters. The supplier of SYV aluminum foil shielded and copper braided shielded coaxial cable tells you that the thick cable is suitable for relatively large local networks. Its standard distance is long and its reliability is high. Since the cable does not need to be cut during installation, it can be flexibly adjusted according to the needs of the computer. Network access location, but transceiver cables must be installed in the thick cable network, which is difficult to install, so the overall cost is high. On the contrary, the installation of thin cables is relatively simple and the cost is low, but because the cable needs to be cut off during the installation process, the basic network connector (BNC) must be installed on both ends, and then connected to both ends of the T-shaped connector, so when there are many connectors, it is easy to produce bad faults. Hidden danger, this is one of the most common faults that occur in the Ethernet in operation at present.
The supplier of SYV aluminum foil shielded and copper braided shielded coaxial cable tells you that whether it is a thick cable or a thin cable, it is a bus topology, that is, multiple machines are connected to one cable. This topology is suitable for a dense machine environment, but when a When a contact fails, the failure affects all machines along the length of the cable in series. The diagnosis and repair of faults are troublesome, so they will be gradually replaced by unshielded twisted pair or optical cables.
