Coaxial Cable Sourcing Guide: RG6, RG11 & Kev daws teeb meem tsawg

Cia peb ua siab ncaj: nyob rau hauv ib qho kev sib txuas lus lossis kev ruaj ntseg, cov cabling feem ntau yog qhov kawg ntawm daim ntawv siv nyiaj, tab sis nws yog thawj qhov ua rau mob taub hau yog tias nws ua tsis tiav. Txawm hais tias koj tab tom xaim lub siab - chav tsev qhov ntom ntom rau broadband lossis teeb tsa lub network CCTV tseem ceeb, qhov zoo ntawm kojcoaxial kabtxiav txim siab qhov kev ntseeg ntawm tag nrho cov system.

Koj tsis yog yuav hlau xwb; koj tab tom yuav teeb liab kev ncaj ncees. Raws li tus neeg yuav khoom B2B, qhov sib txawv ntawm kev lag luam gimmick thiab qhov ruaj khov tiag tiagcoaxial kabNws yog ib qho tseem ceeb rau khaws koj cov nqi tu thiab koj cov neeg siv khoom zoo siab.

Kev txiav txim siab tus qauv: RG6, RG59, lossis RG11 Coaxial Cable?

Yog tias koj tshawb xyuas cov ntawv teev npe, koj yuav pom cov ntawv sau cov ntawv qhia tshwj xeeb. Tab sis rau 90% ntawm kev lag luam daim ntawv thov, nws los rau peb lub ntsiab contenders. Xaiv qhov tsis ncaj ncees lawm tsis yog ib qho kev ua yuam kev xwb; nws yog ib qho kev pheej hmoo nyiaj txiag.

RG59:Koj tseem yuav pom qhov no hauv cov kab ke qub txeeg qub teg thiab cov teeb tsa analog CCTV yooj yim. Nws muaj ib tug thinner core thiab siab dua teeb liab poob. Tshwj tsis yog tias koj tab tom kho cov txheej txheem qub lossis ua luv luv, qis - zaus khiav, peb feem ntau qhia txog kev kho dua tshiab.

RG6 Coaxial Cable:Qhov no yog cov neeg ua haujlwm hauv kev lag luam. Txawm hais tias nws yog rau satellite TV, digital cable, lossis broadband internet, RG6 muab qhov chaw qab zib ntawm kev yoog raws thiab cov teeb liab tuav. Rau feem ntau cov vaj tse thiab teeb pom kev lag luam, qhov no yog koj mus -rau.

RG11:Xav txog RG11 li RG6 ntawm steroids. Nws yog thicker, nyuaj rau khoov, tab sis ua tau zoo heev nyob rau hauv ntev kev deb. Yog tias koj lub cable khiav tshaj 1500 ko taw, hloov mus rauRG11 coaxial cabletuaj yeem txuag koj ntawm kev xav tau cov teeb liab kim amplifiers nruab nrab ntawm txoj kab.

Qhov "Invisible" Specs: Vim li cas Shielding thiab Impedance Matter

Ntawm no yog qhov uas cov kws txawj cais lawv tus kheej los ntawm cov amateurs. Lub cable yuav zoo li muaj zog nyob rau sab nraud, tab sis cov duab puab sab hauv qhia txog zaj dab neeg tiag tiag.

75 Ohm vs . 50 Ohm: Xaiv txoj cai impedance

Qhov no yog qhov teeb meem feem ntau hauv kev xa khoom. Koj yuav tsum phim lub cable rau cov khoom siv.

75 Ohm Coaxial Cable:Qhov no yog tus qauv rau kev yees duab thiab suab (CCTV, CATV). Siv qhov no rau kev xa cov ntaub ntawv feem ntau ua haujlwm, tab sis nws tsis zoo.

50 Ohm Coaxial Cable:Qhov no yog lub neej rau cov ntaub ntawv thiab kev sib txuas lus wireless. Yog tias koj tab tom cuam tshuam nrog cell boosters, WiFi extenders, los yog ob- xov tooj cua, koj xav taulow poob coaxial cablentsuas ntawm 50 Ohms kom txo qis attenuation.

Braid Coverage thiab Khoom siv: Copper vs. CCS

Thaum koj strip rov qab lub tsho, koj pom dab tsi? Hauv kev ua lag luam B2B, tus nqi siab feem ntau thawb cov neeg xa khoom kom muab CCS (Copper Clad Steel) cov neeg siv khoom. Rau siab - cov ntaub ntawv zaus, CCS feem ntau zoo vim yog "cov nyhuv ntawm daim tawv nqaij." Txawm li cas los xij, rau qis - zaus xa hluav taws xob (xws li lub hwj chim lub koob yees duab hla lub coax),

Khoom Toojtsis yog -negotiable.

Tsis tas li ntawd, saib covbraid npog. Ib tug pheej yig cable yuav muaj 60% braid kev pab them nqi, cia cuam tshuam (EMI) nkag mus rau hauv. Rau lub hom phiaj - ib puag ncig tseem ceeb, ib txwm teev tsawg kawg yog 90% los yog "Quad Shield" configurations los xyuas kom meej koj cov teeb liab nyob twj ywm huv si.

Sab nraum zoov thiab Plenum Rated: Xaiv lub tsho zoo rau koj qhov project

Kojcoaxial kabtsuas yog zoo li nws tiv thaiv cov ntsiab lus.

PVC (Polyvinyl Chloride):Zoo rau kev siv sab hauv tsev, tab sis tsis txhob cia nws pom lub hnub. UV rays yuav tawg tus qauv PVC hauv lub hlis.

PE (Polyethylene):Tus qauv rausab nraum zoov coaxial cable. Nws yog UV resistant thiab waterproof. Zoo meej rau kev faus ncaj qha los yog kev khiav hauv huab cua.

LSZH (Low Smoke Zero Halogen):Qhov tseem ceeb rau kev lag luam European nruj lossis cov chaw pej xeem kaw xws li tshav dav hlau thiab tsev kho mob. Yog tias nws hlawv, nws yuav tsis tso cov pa phem.

Yuav Ua Li Cas Vet Reliable Bulk Coaxial Cable Suppliers

Kev muab khoombulk coaxial cablelos ntawm txawv teb chaws tuaj yeem xav zoo li kev twv txiaj. Koj ua li cas kom ntseeg tau qhov sib xws? Tsis txhob saib tus nqi ib 'meter' xwb. Nug cov ntawv xeem. Lub chaw tsim khoom muaj koob npe yuav tsum muaj peev xwm muab cov ntaub ntawv xeem cheb (feem ntau mus txog 3GHz) uas qhia qhov nkhaus nkhaus.

Kev sib raug zoo yog qhov tseem ceeb. Koj tsis xav kom tus thawj reel zoo meej thiab tus thib kaum reel kom muaj qhov tawm -tus neeg xyuas pib. Saib rau cov neeg muag khoom uas muaj lawv cov kab extrusion thiab muab kev lees paub meej ntawm lub tsho ncaj ncees.

Kab hauv qab: Tsis txhob cia Cabling yog koj qhov txuas tsis muaj zog tshaj

Thaum kawg ntawm hnub, koj lub network tsuas yog ceev (thiab ruaj khov) raws li cov xaim uas nqa nws. Txawm hais tias koj yog ISP nthuav koj cov hneev taw lossis tus neeg saib xyuas kev ruaj ntseg tiv thaiv kev lag luam, xaiv txoj caicoaxial kabyog kev nqis peev hauv koj lub koob npe nrov.

Pheej yig, generic cables yuav txuag koj ob peb xees ib ko taw hnub no, tab sis tus nqi ntawm dov lub tsheb thauj khoom los hloov cov kab degraded xyoo tom ntej yuav so tawm cov nyiaj khaws cia tam sim ntawd.

Npaj kom ruaj ntseg rau koj cov saw khoom?Peb tsis yog muag cable xwb; peb engineer connectivity.Hu rau peb pab neeg hnub norau ib qho kev cai tsocai ntawm kev txiav txim ntau lossis thov cov khoom siv coj mus kuaj. Cia peb ua kom koj qhov project tom ntej yog wired rau kev vam meej.
