Coaxial is a digital coaxial interface; coaxial cables can be divided into baseband coaxial cables and broadband coaxial cables in terms of use; coaxial cables are divided into two categories: 50Ω baseband cables and 75Ω broadband cables; baseband Cables are further divided into thin coaxial cables and thick coaxial cables. The baseband cable is only used for digital transmission, and the data rate can reach 10Mbps.

coaxial refers to coaxial coaxiality. Digital coaxial interface often used in electrical appliances such as DVD computers.
Also refers to coaxial cable. Coaxial cable (coaxial) refers to a cable with two concentric conductors, and the conductor and shielding layer share the same axis.
Basic content
Coaxial cables can be divided into baseband coaxial cables and broadband coaxial cables (i.e. network coaxial cable and video coaxial cable). Coaxial cables are divided into two types: 50Ω baseband cables and 75Ω broadband cables. Baseband cables are further divided into thin coaxial cables and thick coaxial cables. Baseband cables are used only for digital transmission, with data rates up to 10Mbps.
Network coaxial cable
(COAXIAL CABLE) A cable composed of mutually insulated coaxial core conductors inside and outside: the inner conductor is copper wire , the outer conductor is copper tube or mesh. The electromagnetic field is enclosed between the inner and outer conductors, so the radiation loss is small and it is less affected by external interference
. Commonly used to transmit multiple telephone calls and television.
The name of coaxial cable is related to its structure. Coaxial cable is also one of the most common transmission media in local area networks. The pair of conductors used to transmit information are selected according to a structure in which a cylindrical outer conductor is placed outside the inner conductor (a thin core), and the two conductors are isolated from each other by insulating material. The outer conductor and The center of the circle of the central axis core line is on the same axis, so it is called a coaxial cable. The reason why the coaxial cable is designed like this is to prevent external electromagnetic waves from interfering with the transmission of abnormal signals.
