Coaxial Cable
1. Cov qauv thiab cov khoom siv:
Coaxial hlau muaj ib tug neeg xyuas pib qhwv nrog ib txheej ntawm insulating ua npuas ncauj khoom. Tus neeg xyuas pib sab nrauv yog symmetrically surrounded los ntawm cov hlau thaiv, thiab txheej txheej sab nrauv yog tiv thaiv los ntawm cov yas sheath. Vim nws cov khoom rwb thaiv tsev, coaxial cables tuaj yeem nqa cov teeb liab analog nrog ntau qhov ntau zaus.
2. Kev siv:
Nws yog dav siv los txuas xov tooj cua transmitters, receivers, antennas, computer networks, digital audio thiab lwm yam kev siv.
3. Qhov zoo thiab qhov tsis zoo:
Coaxial cable yog yooj yim rau nruab thiab kuj tiv thaiv kev cuam tshuam. Txawm li cas los xij, nws yog qhov loj heev. Vim muaj qhov attenuation siab thiab tus nqi siab ntawm kev sib kis mus ntev, nws tsuas yog tsim nyog rau kev sib kis luv luv.
Twisted Pair
1. Cov qauv thiab hom:
Twisted khub yog ib txoj kab sib kis nrog 4-core lossis 8-core khub qauv. Raws li qhov kev cuam tshuam ib puag ncig, nws tuaj yeem muab faib ua ob hom: shielded twisted khub thiab unshielded twisted khub.
2. Kev siv:
Shielded twisted khub cables feem ntau yog siv nyob rau hauv high-speed thiab high-shielding network ib puag ncig, thaum unshielded twisted khub cables yog siv rau zoo tib yam Ethernet.
3. Qhov zoo:
Twisted khub cables yog qhov yooj yim tshaj plaws thiab pheej yig tshaj ntawm peb lub cables, thiab yooj yim rau nruab thiab khiav lag luam.
Fiber Optic Cable
1. Qauv thiab muaj nuj nqi:
Fiber optic cable muaj ib los yog ntau dua optical fibers, nrog rau ob peb silica core qauv. Txhua qhov no tuaj yeem ua kom haum rau ntau lub wavelengths lossis channels, tso cai rau cov fiber ntau kho qhov muag kom haum rau cov ntaub ntawv muaj peev xwm ntau ntxiv. Thaum txiav tawm nrog cov khoom sib txuas xws li LC-LC, LC-SC, LC-ST, SC-SC, thiab lwm yam, kev sib txuas ntawm fiber ntau ntawm cov khoom siv tau pom tau.
2. Qhov zoo:
Raws li ib qho ntawm cov xov xwm nrov tshaj plaws rau kev txhim kho cabling tshiab thiab txhim kho, kho qhov muag fiber ntau yog lub teeb hauv qhov hnyav thiab me me. Txij li thaum tus neeg xyuas pib yog iav, tsis muaj tam sim no tuaj yeem ntws, thiab fiber ntau optic cable tsis raug cuam tshuam rau electromagnetic cuam tshuam. Qhov zoo tshaj plaws ntawm fiber ntau optic cable yog tias nws tuaj yeem xa cov ntaub ntawv ntau ntawm qhov ntev thiab kev kub ceev nrog tsawg poob.
3. Qhov tsis zoo:
Txawm li cas los xij, nws yuav tsum muaj kev txawj ntse hauv kev txhim kho, yog qhov nyuaj dua los daws, thiab raug nqi ntau heev hauv lub sijhawm luv.
Cov ntsiab lus sib piv
Hauv kev xaus, txhua yam ntawm peb hom cables muaj nws tus yam ntxwv tshwj xeeb thiab kev siv.
Coaxial cables yog tsim rau qee qhov kev siv luv luv uas cuam tshuam tsis kam yog qhov tseem ceeb.
Twisted khub cables yog ib qho kev xaiv zoo rau ntau yam kev sib txuas lus vim lawv qhov yooj yim thiab yooj yim ntawm kev teeb tsa.
Fiber optic cables, ntawm qhov tod tes, yog qhov zoo tshaj plaws rau kev kub ceev, cov ntaub ntawv xa mus ntev, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj kev cuam tshuam electromagnetic.
Thaum xaiv ntawm cov cables, yam xws li cov kev thov tshwj xeeb, kev ncua deb ntawm kev sib kis, kev siv nyiaj txiag, thiab kev teeb tsa nyuaj yuav tsum tau txiav txim siab.
