產(chǎn)品分類：

Product classification:

目前，常用的射頻同軸電纜有兩類：50Ω和75Ω的射頻同軸電纜。

At present, there are two types of commonly used RF coaxial cables: 50 Ω and 75 Ω RF coaxial cables.

特性阻抗75Ω射頻同軸電纜常用于CATV網(wǎng)，故稱為CATV電纜，傳輸帶寬可達(dá)1GHz，目前常用CATV電纜的傳輸帶寬：750MHz。

RF coaxial cables with a characteristic impedance of 75 Ω are commonly used in CATV networks, hence they are called CATV cables, with a transmission bandwidth of up to 1GHz. Currently, the transmission bandwidth of commonly used CATV cables is 750MHz.

特性阻抗50Ω射頻同軸電纜主要用于基帶信號傳輸，傳輸帶寬為1～2OMHz，

RF coaxial cables with a characteristic impedance of 50 Ω are mainly used for baseband signal transmission, with a transmission bandwidth of 1-2OMHz,

一般特性阻抗50Ω細(xì)同軸電纜的傳輸距離為180米，粗同軸電纜可達(dá)1000米。

The transmission distance of a thin coaxial cable with a general characteristic impedance of 50 Ω is 180 meters, while a thick coaxial cable can reach up to 1000 meters.

射頻同軸電纜的得名與它的結(jié)構(gòu)相關(guān)。射頻同軸電纜也是局域網(wǎng)中的傳輸介質(zhì)之一。它用來傳遞信息的一對導(dǎo)體是按照一層圓筒式的外導(dǎo)體套在內(nèi)導(dǎo)體（一根細(xì)芯）外面，兩個(gè)導(dǎo)體間用絕緣材料互相隔離的結(jié)構(gòu)制選的，外層導(dǎo)體和中心軸芯線的圓心在同一個(gè)軸心上，所以叫做射頻同軸電纜，射頻同軸電纜之所以設(shè)計(jì)成這樣，也是為了防止外部電磁波干擾異常信號的傳遞。

The name of RF coaxial cable is related to its structure. RF coaxial cables are also one of the transmission media in local area networks. The pair of conductors it uses to transmit information are selected according to a structure of a cylindrical outer conductor sheathed outside the inner conductor (a thin core), and the two conductors are isolated from each other by insulating materials. The center of the outer conductor and the central axis core wire are on the same axis, so it is called a radio frequency coaxial cable. The reason why the radio frequency coaxial cable is designed in this way is also to prevent external electromagnetic waves from interfering with the transmission of abnormal signals.

射頻同軸電纜根據(jù)其直徑大小可以分為：粗射頻同軸電纜與細(xì)射頻同軸電纜。粗纜適用于比較大型的局部網(wǎng)絡(luò)，它的標(biāo)準(zhǔn)距離長，可靠性高，由于安裝時(shí)不需要切斷電纜，因此可以根據(jù)需要靈活調(diào)整計(jì)算機(jī)的入網(wǎng)位置，但粗纜網(wǎng)絡(luò)須***安裝收發(fā)器電纜，安裝難度大，所以總體造價(jià)高。相反，細(xì)纜安裝則比較簡單，造價(jià)低，但由于安裝過程要切斷電纜，兩頭須裝上基本網(wǎng)絡(luò)連接頭（BNC），然后接在T型連接器兩端，，這是目前運(yùn)行中的以太網(wǎng)所發(fā)生的故障之一。

RF coaxial cables can be divided into coarse RF coaxial cables and fine RF coaxial cables based on their diameter. Coarse cables are suitable for relatively large local networks, with long standard distances and high reliability. As installation does not require cutting off cables, the computer's network access position can be flexibly adjusted according to needs. However, thick cable networks must install transceiver cables, which is difficult to install, resulting in high overall cost. On the contrary, the installation of thin cables is relatively simple and cost-effective, but due to the need to cut off the cables during the installation process, basic network connectors (BNC) must be installed on both ends and then connected to both ends of the T-connector, which is one of the faults that currently occur in operating Ethernet.
