Coaxial cables
Coaxial cablesYog cov qauv cable uas muaj cov qauv ntawm cov neeg sab hauv, cov tsho sib xyaw (RFI) thiab cov xov tooj cua sib koom ua ke (RFI) thiab cov xov tooj cua sib xyaw ua ke Cov cable no tau siv nyob rau hauv TV teeb liab kis tau tus kis, cable TV network, thiab yog ib qho ntawm cov kev sib txuas ntawm cov khoom sib txuas lus hauv kev sib txuas lus cable.
Qhov Zoo
Cov qauv ruaj khov
Lub ntsej muag sab nraud tiv thaiv tus qauv sab hauv, muaj qee qhov kev hloov kho lub cev thiab ib puag ncig kev yoog tau, thiab haum rau ntau qhov chaw teeb tsa.
Tsawg lub teeb liab poob
Qhov ploj hauv nruab nrab thiab kev sib kis tau ntsuas qhov hluav taws xob loj yog qhov me me, ua rau nws haum rau kev sib kis mus ntev.
Muaj zog tiv thaiv kev cuam tshuam muaj peev xwm
Cov neeg xyuas pib sab nraud (daim thaiv npog txheej) tuaj yeem thaiv hluav taws xob hauv hluav taws xob cuam tshuam (EMI) thiab xov tooj cua tiv thaiv kev cuam tshuam (RFI).

Los ntawm cov qauv & kev ua tau zoo
Hlua khi hlua cable: Cov hom general-hom phiaj, xws li RG-6 (qis siv cable TV), RG-nyob ntev kis), RG-59 (thicker, luv-ntau video).
Nkauj Tawm Lab Cable: Kev ua tau zoo thiab tsis muaj kev poob siab, xws li LMR-400 (nruab nrab (LMR-600 (ntev ntev cov kev siv hluav taws xob).
Patentaled Cable: Cov txheej txheej sab nraud yog cov hlau, tiv taus rau kev puas tsuaj rau kev puas tsuaj, haum rau ib puag ncig hnyav xws li sab nraum zoov thiab hauv av.
Los ntawm daim ntawv thov
· Kev sib tham sib txuas lus: Rau cov chaw nres tsheb hauv paus, taw tes-rau-taw RF txuas (piv txwv li, LMR-400, RG-8).
Eg Tshaj Tawm Xov Xwm: Cable, satellite kev hloov pauv (piv txwv li, RG-6, RG-11).
· Inder are Kev Siv / Ntsuas Cables: Muaj kub thiab qis thiab tsis tshua muaj cua, qis dua intermodulation rau aerospace, khoom siv kho mob (piv txwv li, lab-flex® s series).
Cov FAQ
Q: Qhov kev thov tshwj xeeb ntawm coaxial cable hauv kev sib txuas lus network?
A:
1. Cable TV (MOB)
2. Broadband nkag (Docisis thev naus laus zis): Muab cov ntaub ntawv loj kawg nkaus rau cov tsev thiab cov lag luam los ntawm hybrid fiber ntau cov tes hauj lwm (HFC).
{{03. 5 g blects chaw nres tsheb RF Kev sib txuas ntawm cov chaw nres tsheb kav hlau txais xov thiab xov tooj cua (rrus), tshwj xeeb yog nyob rau hauv sub-6ghz zaus band.
Q: Dab tsi yog qhov sib txawv ntawm cov roj fiber optic cable thiab coaxial cable?
A:
1. Kev siv lub ntsej muag siv lub teeb pom kev zoo rau cov ntaub ntawv xa tawm (cov paib teeb) nrog tag nrho cov kev xav hauv cov iav / yas fibers.
Cov CABLE CABLE CABGS PARDALSALLES LOS NTAWM LUB TEB CHAWS RAU HAUV LUB CENTRAL LUB CEV THIAB ORTER ROJ.
2. Cov fiber ntau optic cable bandwidth yog ultra-siab, nce mus txog theem kev sib nrug tuaj yeem ncav tau mus txog 100 km.
Coaxial cable bandwidths feem ntau <10 gbps thiab kis tau tus mob sib nrug yog ib nrab, feem ntau <500 meters.
3. Qhov chaw muag khoom siv hluav taws xob feem ntau yog siv hauv pob txha caj qaum (xws li 5G chaw nres tsheb hauv chaw nres tsheb), cov ntaub ntawv sib txuas lus (submarine cables), thiab high-txhais nyob video.
Coaxial clesles yog siv nyob rau hauv lub tsev broadband (Docisis thev naus laus zis), Cable tshuaj xyuas, thiab luv luv xov tooj ntawm lub rooj zaum satellite).
4. Thawj zaug xa tawm cov nqi kho mob cable yog qhov siab, yuav tsum tau siv cov khoom siv sib cav, tab sis tus nqi tswj kev nyab xeeb ntev yog tsawg.
Coaxial clesles yog qhov yooj yim thiab pheej yig rau nruab, tab sis yuav tsum tau tu cov ntaub thaiv npog thiab txuas los tiv thaiv oxidation.
Q: Dab tsi cuam tshuam rau tus nqi ntawm coaxial cable?
A:
1. Cov ntaub ntawv nyoos raw ntawm cov cable coaxial xws li tooj liab thiab txhuas, nrog rau cov ntaub ntawv insulating xws li yas. Hloov pauv hloov pauv tooj liab thiab Aluminium nqi yuav cuam tshuam nrog tus nqi ntawm cov xaim tooj liab, feem ntau yog tooj liab-dawb tooj yog kim dua li cov tooj liab zoo dua li qub decoder. Ntau yam ntawm rwb thaiv tsev thiab cov ntaub ntawv sheathing kuj cuam tshuam rau tus nqi, xws li hla cov polyethylene (xlpe), uas yog kim dua li ib txwm siv ib txwm pvc.
2. Qhov loj dua tus txiv neej hla kev hla ntu ntawm cov cable thiab ntau dua cov ntsuas hluav taws xob (siab dua tus nqi. Tus nqi ntawm coaxial clesles nrog cov kev cuam tshuam sib txawv txawv, xws li 50 feem ntau siv rau RF kev sib txuas lus thiab 75ω rau TV teeb liab kev kis tau tej zaum yuav txawv. Tsis tas li ntawd, coaxial cables rau cov xaim hluav taws xob tshwj xeeb, yog ntau dua cov kev xav tau tshwj xeeb, muaj ntau yam kev cai tshwj xeeb thiab muaj kev ruaj khov nyob ruaj khov.
3. High-xaus lossis tshwj xeeb hom coaxial cable, ntau dua cov txheej txheem kev tswj hwm, thiab cov nqi ntau lawm, thiab tus nqi siab dua, thiab tus nqi siab dua.
