Ukuhlukaniswa kwezintambo ze-coaxial

1, Ngokuvumelana ne-impedance, ingahlukaniswa ngama-ohms angu-50 (RG8/RG58/RG-11), 75 ohms (RG-11), 93 ohms (RG62).

2, ngokuvumelana nobubanzi be-ikhebula, ingahlukaniswa ngekhebula elimahhadla nelicolekile.

Ikhebula elimahholo lishintshashintsha kancane ngenxa yogqinsi lwalo, futhi lifanele amanethiwekhi endawo amakhulu, anebanga elide elijwayelekile (ibanga eliphezulu lokudlulisela elifika ku- 500 metres) nokuthembeka okuphezulu.

Ngenxa yokuthi ukufakwa akudingi ukusika ikhebula, ngakho-ke ungakwazi ukulungisa kalula indawo yokungena kwikhompyutha njengoba kudingeka, kodwa inethiwekhi yekhebula eliwugqinsi kufanele ifakwe i-transceiver cable, ukuyifaka kunzima, izindleko zizonke ziphezulu.

Ukufakwa kwekhebula elihle kulula futhi kubiza kancane, kodwa njengoba ikhebula kufanele linqanyulwe ngesikhathi sokufakwa, isixhumi esiyisisekelo senethiwekhi (BNC) kufanele sifakwe kuzo zombili iziphetho bese sixhunywa kuzo zombili. iziphetho T-isixhumi, ngakho lapho kukhona izixhumi eziningi, kulula ukukhiqiza izinkinga ezimbi ezifihliwe, okungenye ukwehluleka ezivame kakhulu Ethernet ukusebenza.

3, Ngokusho imodi yokudlulisela, kungaba ihlukaniswe nge-baseband coaxial cable kanye nekhebula le-broadband coaxial.

Baseband coaxial cable: esetshenziselwa ukudluliswa kwedatha, ngaphakathi kwe-1Km, izinga lingafinyelela ku-1-2Gb/s.

Broadband coaxial cable: esetshenziselwa 300MHz~750MHz ukudluliselwa kwesignali ye-analog (FDM).

Omunye umehluko omkhulu phakathi kwe-broadband nezinhlelo ze-baseband ukuthi amasistimu e-broadband adinga ama-amplifiers e-analog ukuze ngezikhathi ezithile aqinise isignali ngenxa yendawo ebanzi emboziwe.

Lezi zikhulisi zingadlulisela amasignali ohlangothini olulodwa kuphela, ngakho-ke amaphakethe emilayezo awakwazi ukudluliselwa ohlangothini olubuyela emuva phakathi kwamakhompyutha uma kukhona ama-amplifiers phakathi kwamakhompyutha. Intambo ayilungile, kodwa inobuhle bokuthi ifakwe kabanzi.

4, ngokokusetshenziswa, ingahlukaniswa ngekhebula, ukufinyelela okungenantambo kusiphakeli, inethiwekhi yedatha ye-broadband.
