Yintoni intambo yeCoaxial?

A intambo ye-indibaniselwanoial("indibaniselwano" in English) is a cable composed of two indibaniselwanoial, mutually insulated cylindrical metal conductors to form a basic unit (indibaniselwanoial pair), kwayethen a single or multiple indibaniselwanoial pairs. It has been used to transmit data kwayevideo signals for a long time.

It is one of the first media to support 10BASE2 kwaye10BASE5 Ethernet, which can achieve 10 Mb/s transmission up to 185 meters or 500 meters, respectively. The term "indibaniselwanoial" means that the central conductor of the cable kwayeits shield have the same axis or center point. Some intambo ye-indibaniselwanoials may have multiple shielding layers, such as a four-shielded intambo ye-indibaniselwanoial, which contains two layers of shielding, kwayeeach layer of shielding is composed of aluminum foil wrapped with wire mesh. The shielding characteristics of intambo ye-indibaniselwanoial make it have strong anti-electromagnetic interference ability kwayecan transmit high-frequency signals over long distances. There are many different types of main types of intambo ye-indibaniselwanoials that support a wide range of professional applications, such as satellite communications, industrial, military kwayemarine applications. The three most common types of non-industrial intambo ye-indibaniselwanoials are RG6, RG11kwayeRG59, ngokubaRG6isetyenziswa kakhulu kwiCCTV kwayeCATVizicelo kwiindawo ezihlanganisiweyo. Umqhubi wezikoRG11ujiyile kuneRG6, which means that its insertion loss is lower kwayethe signal transmission distance is longer.

Nangona kunjalo, ziyatyebaRG11 iintambo are more costly kwayevery difficult to bend, which makes them unsuitable for deployment in internal applications, but more suitable for long-distance outdoor installations or straight backbone links. RG59iguquguquka ngakumbi kuneRG6, but its loss is higher. It is rarely used in other applications except for low-bandwidth, low-frequency analog video applications (rear-view cameras in automobiles) with short distances kwayelimited wiring space. Iintambo zeCoaxial also have different impedances-usually 50, 75, kwaye93 Ω. 50Ω intambo ye-indibaniselwanoials have high power handling capabilities kwayeare mainly used in radio transmitters such as amateur radio equipment, civil bkwayeradio (CB) kwayewalkie-talkies. 75 Ω cables can maintain signal strength well kwayeare mainly used to connect various types of receiving equipment, such as cable television (CATV) receivers, high-definition televisions kwayedigital video recorders. 93 Ω CIntambo ye-oaxial was used in IBM mainframe networks in the 1970s kwayeearly 1980s, with very few applications kwayeexpensive. Although the 75 Ω intambo ye-indibaniselwanoial impedance is most commonly encountered in most applications today, it is important to note that all components in the intambo ye-indibaniselwanoial system should have the same impedance to avoid possible signal loss kwayesignal loss at the connection point. Internal reflections that reduce video quality. The digital signal 3 (DS3) signal used in the central office (also known as T3 line) transmission service also uses intambo ye-indibaniselwanoials, including 75 Ω 735 type kwaye734 type. The 735 type cable has a coverage distance of 69 meters, while the 734 type cable has a coverage distance of 137 meters.Intambo ye-RG6Ingasetyenziselwa ukuhambisa imiqondiso yeDS3, kodwa umgama wokugubungela umfutshane.
