Network cable feem ntau siv ntau hom xaub hlau. Nyob ntawm daim ntawv thov cov xwm txheej thiab cov kev xav tau, hauv qab no yog hom feem ntau ntawm cov xov xwm network:
1. Twisted khub
Txhais thiab Nta: Twisted khub cables yog cov ntaub ntawv kis tau cables muaj ntau khub ntawm cov xov hlau. Lawv pheej yig, muab cov kev sib kis ceev ceev, thiab yooj yim rau nruab thiab tswj. Txhua khub nyob rau hauv ib khub khub uas muaj ob tus neeg soj ntsuam ntxig rau cov ntsia hlau sib xyaw ua ke kom txo tau electromagnetic cuam tshuam.
Kev cais tawm: Twisted khub cables tau muab faib ua daim thaiv npog sib piv khub (STP) thiab unssield twisted khub (utp). UTP yog qhov feem ntau siv hom network cable hauv cheeb tsam chaw (lans). Nws muaj yim lub teeb liab xov hlau, sib ntswg ua ke hauv khub ntawm ob, sib sau plaub khub.
Cov kev faib tawm tshwj xeeb: Raws li kev sib kis kev sib kis thiab kev ua tau zoo, Cat5E), qeb 5 (Cat5E), qeb 6A (Cat6E), thiab qeb 7 (Cat7). Qeb 5E thiab ntau dua cov cable tuaj yeem txhawb nqa gigabit lossis txawm tias 10gbe tes hauj lwm.
2. Coaxial cable
Cov ntsiab lus thiab cov yam ntxwv: coaxial cable yog cable nrog ob qho kev saib xyuas, nrog cov neeg sab hauv thiab ntaub thaiv npog ib txwm muaj axis. Vim tias tus naiskoj tseem ceeb nyob ib puag ncig los ntawm cov khoom siv insulating thiab mesh {1} Zoo li cov ntaub thaiv hlau xaim, cuam tshuam nrog kev sib txuas lus zoo.
Kev faib tawm thiab cov ntawv thov: Coaxial cables tau categorized li nyias thiab tuab. Cov qoob loo nyias yog ib zaug siv nyob hauv Ethernet tes hauj lwm, tab sis tam sim no tsawg dua siv vim lawv txoj kev sib nyiam thiab ntxim nyiam kev puas tsuaj. Tuab cab, txawm li cas los xij, tsis tshua muaj siv nyob rau hauv cov tsev raug lossis cov tes hauj lwm me vim lawv tus nqi siab thiab cov txheej txheem kev teeb tsa ntau thiab nyuaj.
3. Fiber Optic Cable
Cov ntsiab lus thiab cov yam ntxwv: Fiber Optic Cable yog ib hom network cable uas siv lub teeb pulses los xa cov paib. Ua cov iav lossis Plexiglass, nws muaj cov txiaj ntsig zoo xws li muaj kev kub ceev, thiab muaj zog}- kev cuam tshuam muaj peev xwm. Cov qauv tseem ceeb ntawm cov fiber ntau cable yog ib qho kho tshiab fiber ntau ua los ntawm cov iav los yog pob tshab yas, puag ncig los ntawm cov khoom tiv thaiv.
Kev faib tawm thiab cov ntawv thov: Fiber ntau cov kab yuav raug faib ua ib qho} hom lossis multimode, nyob ntawm seb lawv tsim kho qhov kho tshiab. Siv lub fiber ntau tau siv dav hauv cov xwm txheej uas yuav tsum tau bandwidiT thiab ntev}} huab cua nrug, xws li Enterprise Networks thiab cov ntaub ntawv cov chaw.
