Lub network cable, tseem hu ua cov ntaub ntawv cable lossis network cable, ua haujlwm nruab nrab rau kev xa cov ntaub ntawv los ntawm ib lub network (xws li lub computer) mus rau lwm qhov.Nws yog ib qho tseem ceeb thiab tseem ceeb ntawm txhua lub network system, ua kom cov ntaub ntawv xa mus thiab kev sib txuas lus ntawm cov khoom siv.
1. Hom Network Cables:
Twisted Pair Cable (UTP / STP):
Feem ntau siv hom network cable.
Muaj plaub khub ntawm cov xov tooj tooj liab sib tw ua ke kom txo tau cov electromagnetic cuam tshuam.
Unshielded Twisted Pair (UTP) yog qhov ntau tshaj plaws, thaum Shielded Twisted Pair (STP) muaj kev tiv thaiv ntxiv rau kev cuam tshuam.
Haum rau kev sib kis luv luv, feem ntau siv hauv Local Area Networks (LANs).
2. Coaxial Cable:
Tsim los nrog ib tug tooj liab los yog txhuas core puag ncig los ntawm ib tug conductive shielding txheej thiab insulated khoom.
Muaj peev xwm nqa tau cov teeb liab nrog cov zaus siab, siv feem ntau rau cov teeb liab analog TV thiab qee qhov kev sib txuas hauv internet broadband.
Tsis tshua muaj nyob rau niaj hnub kev sib txuas lus vim qhov nce ntawm cov teeb liab digital thiab fiber optic cables.
3. Fiber Optic Cable:
Ua los ntawm iav los yog yas fibers uas xa cov ntaub ntawv siv pulses ntawm lub teeb.
Muab cov bandwidth siab, kev xa mus ntev nrog cov teeb liab tsawg tsawg.
Qhov zoo tshaj plaws rau cov caj qaum thiab ntev-ntev kev sib txuas network.
Nta thiab qhov zoo ntawm Network Cables:
Flexibility: Network cables tuaj yeem txuas tau yooj yim thiab teeb tsa hauv ntau qhov chaw.
Nqi-Effectiveness: Twisted khub cables, tshwj xeeb tshaj yog UTP, kuj pheej yig thiab dav muaj.
Scalability: Networks tuaj yeem nthuav dav tau yooj yim los ntawm kev ntxiv ntau cov cables thiab cov khoom siv.
Durability: Network cables yog tsim los tiv thaiv kev hnav thiab tsim kua muag, kom ntseeg tau cov kev sib txuas txhim khu kev qha.
Standards thiab Specifications:
Network cables ua raws li ntau yam kev lag luam qauv, xws li EIA / TIA 568A thiab 568B, uas qhia meej txog kev teeb tsa thiab pinout ntawm cables.
Cov kab sib txawv (Cat 5, Cat 5e, Cat 6, thiab lwm yam) muaj kev sib txawv ntawm kev ua tau zoo, suav nrog bandwidth, zaus, thiab kis ceev.
Hauv cov ntsiab lus, network cables ua lub luag haujlwm tseem ceeb hauv kev sib txuas cov cuab yeej thiab ua kom cov ntaub ntawv sib txuas lus hauv lub network.Kev xaiv ntawm cable hom nyob ntawm seb cov kev xav tau tshwj xeeb ntawm lub network, suav nrog bandwidth, kev sib kis deb, thiab kev txiav txim siab nqi.
