Coaxial Cable - nokwethenjelwa ngesikhathi intengo imali

Ukuze wanamuhla ulwazi umphakathi impahla ebaluleke kakhulu emakethe kukhona imikhiqizo ehlukahlukene, ukuqinisekisa ukudalwa eliphezulu nokunokwethenjelwa Imininingwane yokuxhumana nabezindaba. Omunye wabo ikhebuli coaxial. Wayesebenza kahle uma isetshenziselwa kuhambisane netinhloso.

Coaxial ikhebula digital kabanzi emikhakheni eminingi yomsebenzi womuntu. Ikakhulukazi, isetshenziswa ukuba adlulisele amasignali e-satellite kanye namakhamera wevidiyo. Lokhu kungenxa yokuthi Lifanele adlulisa ephezulu imvamisa pulses. Design Its ekhethekile evumela ukufeza izinga ukulethwa esiphezulu yimuphi amasignali ngaphandle kokulahleka. Kulokhu, ukutholakala kolwazi angadluliselwa olude nge attenuation kangako noma abangafundile nhlobo.

Ngokuvamile, le ntambo coaxial ngokohlaka olulandelayo: okuyinto phakathi umqhubi (kwakhiwa, ngokuvamile zethusi) ibekwe high density polyethylene emazombezombe kokuba izakhiwo Kwe-dielectric Heating futhi isipikili nokwelukiweyo anezikhala of izingcwecwe zensimbi izintambo. Kusukela phezulu kuyahlanganiswa i ukugoqa nangokuvikela of polyethylene noma polyvinyl chloride.

ikhebula Coaxial, njengabanye ukudluliswa ngokomzimba amaphakathi, enezinto eziningi izici ezithile. Ngakho-ke kuyadingeka zisuka ukwazi ngokucacile ngayiphi injongo, kulokho imvelo lizosetshenziswa, futhi kuphela bese ukhetha uhlobo izici ezifanele kakhulu.

Ngokwesibonelo, ikhebula coaxial for video ukubhekwa kufanele abe Izakhiwo ezilandelayo:

1. It ingathunyelwa ngangokunokwenzeka bohlu imvamisa.
2. ithonya Ubuncane kwi olandelayo pass wesifunda lapho ugesi idluliselwa.
3. I ephakeme kakhulu ukumelana amathonya zangaphandle.
4. Ukuvikeleka ukuphazamiseka.

Futhi into okuyiyona ebaluleke kakhulu ukumelana nomsindo ongaphakeme-imvamisa, njengoba lena ethile eyinhloko umkhiqizo elinjalo - ke uchayeke amasignali ngobulili nganoma imisindo ephansi.

ikhebula Coaxial ngokuvamile esetshenziselwa ukudluliswa kwedatha phakathi eyamukelayo kanye namadivayisi okuxhunyanwa. Ungomunye zezindlela ezivame kakhulu ukuba adlulisele amasignali zethelevishini nama-video. nokudlanga wayo akuyona okungenani ngenxa cheapness isihlobo.

Kukhona inombolo kahle esikhulu ezahlukene izintambo coaxial. Umehluko omkhulu itholakala ubunjalo bomzimba. Ngesikhathi esifanayo kuyafaneleka ukuthi isimiso isinyathelo ngesikhathi izinhlobo ezahlukene umkhiqizo ofanayo.

Uma unquma ukufaka kuphi (ekhaya noma ehhovisi) video ukubhekwa uhlelo, the ningi NEMPUMELELO NGAPHAKATHI ukudluliswa naphakathi kuyoba ikhebula ncamashi coaxial. Uzothola uhlelo okuthembekile usebenza imali elincane imali. Futhi yokudlanga inombolo weminikelo emakethe akuvumela ukuba ukhethe umkhiqizo eyofanelana kahle izidingo zakho ngabanye. Lokhu kuzokusiza ukuba asebenzise uhlelo yanoma yimuphi yinkimbinkimbi futhi ekhelini.
