Izisekelo Zekhebula Le-Coaxial

Iyini Ikhebula le-Coaxial?

Ikhebula le-coaxial liyikhebula elikhethekile elenzelwe ukudlulisa isignali ngempumelelo. Linesakhiwo esiyingqayizivele esivumela ukuthi lithwale idatha, ividiyo, kanye nezibonakaliso zomsindo ngaphandle kokuphazamiseka okuncane. Umklamo wekhebula le-coaxial uhlanganisa izendlalelo eziningana, ngayinye isebenzela injongo ehlukile. Umqhubi ophakathi udlulisa isignali, kuyilapho isivikelo se-dielectric sigcina umqhubi ehlukene nesivikelo. I-mesh yethusi elukiwe isebenza njengesivikelo ekuphazamisekeni kwe-electromagnetic, kanti uqweqwe lwepulasitiki luvikela ikhebula ekulimaleni ngokomzimba. Ithebula elingezansi lichaza izingxenye eziyinhloko zesakhiwo kanye nemisebenzi yazo:

Isendlalelo	Umsebenzi
Umqhubi wesikhungo	Iphatha idatha nevidiyo ngentambo yethusi.

Amakhebula Aqinile Kancane Nakancane

Izintambo ze-coaxial eziqinile kancane zine-impedance eqinile kanye nokuvikela okuhle kakhulu. Lezi zintambo zilungele izinhlelo ze-microwave kanye ne-millimeter-wave, kufaka phakathi izindiza, i-radar, kanye nezinsimbi zelebhu. Izintambo ze-micro-coaxial, ezinobubanzi obungaphansi kwe-1 mm, zilingana nezindawo ezivinjiwe njengemishini yezokwelapha, i-radar yezimoto, kanye ne-electronics ephathekayo. Izixhumi eziqondile kanye nokuphathwa kwe-radius yokugoba ngokucophelela kubalulekile kulezi zinhlobo zezintambo ze-coaxial.

Ukukhetha ikhebula le-coaxial elifanele lohlelo ngalunye kuqinisekisa ukusebenza kahle kwesignali kanye nokuthembeka kuzo zonke izinhlelo zokusebenza ze-telecom nezenethiwekhi ezingenantambo.

Izindlela Zokukhetha Ikhebula Le-Coaxial

Ukukhetha ikhebula le-coaxial elifanele kubalulekile ekugcineni ikhwalithi yesignali kanye nokudluliswa okuthembekile kwezokuxhumana kanye nezinhlelo zokusebenza zenethiwekhi engenantambo. Uhlelo ngalunye lunezidingo ezihlukile, ngakho-ke ukufanisa imininingwane yekhebula nohlelo lokusebenza oluhlosiwe kuqinisekisa ukusebenza kahle kanye nokuqina kwesikhathi eside.

Impedance kanye neBanga Lokuphindaphinda

Impedance iyisici esibalulekile ekusebenzeni kwekhebula le-coaxial. Lilinganisa ukumelana nokugeleza kwesiginali ngaphakathi kwekhebula. Amanani empedance avame kakhulu ezintambo ze-coaxial angama-50 ohms nama-75 ohms. Lawa manani awahleliwe. Alungiselelwe ukusetshenziswa okuhlukile:

• Ama-ohm angu-50 ayindlela ejwayelekile yokuxhumana ngemvamisa yomsakazo kanye namanethiwekhi angenantambo.
• Ama-ohm angu-75 ayathandwa kakhulu ezinhlelweni zokudlulisa ividiyo kanye nokusakaza.

Ukuqondanisa ukuvinjelwa kwekhebula nemishini exhunyiwe kuvimbela ukuwohloka kwesiginali. Ukungafani kungabangela ukubonakaliswa, okuholela ezinkingeni ezifana nokungacaci kahle ezikrinini zethelevishini noma ukulahleka kwephakethe ledatha ekuxhumaneni kwe-inthanethi. Ezimweni ezimbi kakhulu, kungalimaza ngisho nezinto zikagesi ezibucayi.

Ukuhambisana kwebanga lemvamisa nakho kubalulekile. Ikhebula ngalinye le-coaxial lisekela ibanga elithile lemvamisa. Ukusebenzisa ikhebula ngaphandle kwebanga layo elilinganiselwe kunciphisa ukusebenza futhi kungabangela ukulahleka kwesiginali. Ikhebula kanye nezixhumi zalo kumele zisekele imvamisa edingekayo yohlelo lokusebenza. Isibonelo:

• Iziteshi zeselula kanye namanethiwekhi e-Wi-Fi ngokuvamile adinga izintambo eziphatha amaza afinyelela ku-6 GHz.
• Izintambo ezisebenzisa imvamisa ephansi zingase zanele ezinhlelweni zethelevishini noma zemvamisa yomsakazo zendabuko.

Ukukhetha i-impedance efanele kanye nobubanzi bemvamisa kuqinisekisa ukudluliswa kwesignali okuphumelelayo futhi kuvimbela izinkinga zenethiwekhi ezibizayo.

Ukuncipha Nokulahlekelwa Yisignali

Ukuncipha kubhekisela ekunciphiseni amandla esignali njengoba ihamba ngekhebula. Lokhu kulahlekelwa kuyanda ngobude bekhebula, imvamisa, kanye nekhwalithi yezinto ezibonakalayo ephansi. Ukuqonda ukuthi ikhebula le-coaxial lisebenza kanjani kusiza ukuchaza ukuthi kungani ukuncipha kubalulekile. Uma ikhebula lide, kulapho isignali iba buthaka khona. Ukuncipha okuphezulu kungabangela ukulethwa kwedatha okungekuhle kanye nokunciphisa ukufinyelela kwe-inthanethi nezinhlelo ezingenantambo.

Izici eziningana zinegalelo ekulahlekelweni kwesiginali:

• Ukulahlekelwa ukumelana okuvela kumqhubi
• Ukulahleka kwe-dielectric ngenxa yokushisa
• Ukulahlekelwa okungafani okuvela ekuxhumekeni okungafanele
• Ukulahleka kokuvuza, ikakhulukazi ezintanjeni zekhwalithi ephansi kumaza aphezulu

Ithebula elingezansi libonisa amazinga ajwayelekile okunciphisa amandla ezinhlobo zekhebula ezivamile ze-coaxial ku-750 MHz:

Uhlobo	Impedance (ohms)	Ukunciphisa okuphezulu, 750 MHz (dB/100 ft)
I-RG-6	75	5.65
I-RG-7	75	4.57

Izici Zokuvikela Nezemvelo

Ukuvikela kungenye isici esibalulekile sezinzuzo zekhebula le-coaxial. Isendlalelo sokuvikela sivimba ukuphazamiseka kwe-electromagnetic yangaphandle (i-EMI) kanye nokuphazamiseka kwemvamisa yomsakazo (i-RFI), okuvikela isignali ngesikhathi sokudlulisa. Izinhlobo zokuvikela zifaka phakathi ukuluka, i-foil, ukuluka okuphindwe kabili, kanye nesivikelo esinezinhlangothi ezine. Izendlalelo eziningi zinikeza ukumelana okungcono kwe-EMI kodwa zingase zandise ukujiya nokuqina kwekhebula.

• Izihlangu ze-braid ne-foil zivame kakhulu ezinhlelweni eziningi ze-telecom kanye ne-inthanethi.
• Izintambo ezinezivikelo ezine zinikeza isivikelo esiphezulu ezindaweni ezinomsindo ophezulu kagesi.

Izici zemvelo nazo zidlala indima ebalulekile ekukhetheni ikhebula. Umswakama, ukugqwala, kanye nemisebe ye-UV kungonakalisa izinto zekhebula. Umswakama ophezulu ungavumela umswakama ukuthi ungene ekushiseni, unciphise amandla e-dielectric futhi wandise ingozi yamasekethe amafushane. Ukugqwala kungandisa ukumelana kukagesi, kuyilapho ukuvezwa kwe-UV kungenza ukushisisa kube buthaka futhi kuveze ama-conductor.

Uma ufaka ngaphandle, khetha izintambo ze-coaxial ezinejakethi zangaphandle eziqinile kanye nokuvikela okuthuthukisiwe. Izintambo ze-Telsto feeder zenzelwe ukumelana nezimo ezinzima, ukuqinisekisa ukusebenza okuthembekile kokubili ezindaweni zangaphakathi nangaphandle.

Ukuhambisana Kwesixhumi Nokuhlanganiswa Kwaso

Ukuhambisana kwezixhumi kubalulekile ekudlulisweni kwesignali okuzinzile kanye nokuthembeka kwesikhathi eside. Izinhlobo zezixhumi ezivame kakhulu kwezokuxhumana kanye namanethiwekhi angenantambo zifaka:

• I-BNC:Isetshenziselwa imishini ye-RF kanye nezimpawu zevidiyo ezingaphansi kwe-4 GHz.
• Uhlobo lwe-F:Kulungele ithelevishini esemoyeni kanye nezimpawu ze-RF zasekhaya.
• Uhlobo lwe-N:Ifanele izinhlelo zokusebenza zezentengiselwano ezinobubanzi obukhulu bemvamisa.
• I-SMB:Ithandwa kakhulu emishinini yezimboni kanye neyezokuxhumana.
