Cat7 cable tseem hu ua Qeb 7 network cable, haum rau 1000BASE-T (Gigabit Ethernet lossis GbE) thiab 10GBASE-T (10 Gigabit Ethernet lossis 10 GbE), raws li cov cable txuas rau lub network infrastructure. Tus qauv muab kev ua tau zoo txog li 600 MHz, thiab qhov siab tshaj plaws kis tau tus mob yog 100m.
Cat7 cable yog dab tsi?
Qeb 7 Cat7 cable tuaj yeem ua tiav kev sib kis tau zoo dua li cov qauv Ethernet dhau los. Cov kab sib tw twisted no tau tiv thaiv tag nrho, yog li nws tuaj yeem raug hu ua shielded twisted khub (SSTP) lossis shielded twisted khub (SFTP) cabling. Sab nraud crosstalk cuam tshuam raug tshem tawm tag nrho, thiab lub suab nrov tiv thaiv tau zoo dua. Lub xya-qib Cat7 tus qauv tau tsim los ntawm International Organization for Standardization (ISO) hauv xyoo 2002, thiab tseem hu ua qeb F cabling. Nws muaj lub neej ntev dua li qeb tsib thiab qeb rau cables thiab muab cov neeg siv nrog ntau dua qhov rov qab los ntawm kev nqis peev.
Qeb 7 cables yog cov txheej txheem tshiab tshaj plaws rau Ethernet thiab lwm yam kev sib txuas ntawm cov thev naus laus zis, thiab tau tsim nrog cov lus qhia nruj me ntsis rau kev tiv thaiv kev sib txuas lus thiab hluav taws xob cuam tshuam. Qeb 7 cables muaj plaub tus kheej thaiv cov hlua khi thiab tag nrho cov kab thaiv kab thaiv, muab cov xov tooj tooj liab rau 100-meter 10 Gigabit Ethernet kis tau tus mob.
Daim ntawv thov ntawm Cat7 cable hauv cov ntaub ntawv chaw: Nws cov txheej txheem xaim yog feem ntau siv rau kev sib txuas ntawm caj qaum ntawm cov servers hauv cov ntaub ntawv chaw, thiab tuaj yeem muab kev sib txuas ceev ceev rau cov ntaub ntawv xa mus hauv lub network.
Kev taw qhia ntawm Qeb 7 cables yuav ua rau muaj kev cuam tshuam tsis zoo ntawm cov kab hluav taws xob kho qhov muag, thiab Cat7 cables yog lwm txoj hauv kev siv fiber ntau hauv cov ntaub ntawv chaw. Nyob rau hauv cov nqe lus ntawm kev nqis peev, tag nrho cov nqi ntawm cov khoom siv tooj liab cable yog tsawg dua li ntawm cov cuab yeej txhawb nqa optical fiber cable. Tsis tas li ntawd, cov hlau tooj liab yog ib qho yooj yim rau kev khiav lag luam thiab txhim khu kev qha hauv cov xov hlau, thiab cov fiber ntau optical cable yog qhov tsis yooj yim thiab yooj yim rau kev puas tsuaj.
Puas muaj qhov sib txawv loj ntawm Cat7 thiab Cat5e/6 hauv kev siv tswv yim? Cat7 cables txhawb cov teeb liab ntau dua li Cat5e thiab Cat6, thiab tso cai rau kev sib kis ntawm cov ntaub ntawv muaj peev xwm ntau dua. Cat7 cable muaj zog tiv thaiv lub peev xwm rau lub cable kis tau tus mob teeb liab, thiab yog ntau txhim khu kev qha, uas yuav pab txo tau ntawm crosstalk thiab electromagnetic cuam tshuam.
Kev siv Cat7 tsis tau nthuav dav. Hais txog cov ntaub ntawv network luv luv, Cat5e thiab Cat6 cov kev daws teeb meem tuaj yeem ua tau raws li cov kev cai bandwidth niaj hnub no' cov chaw zov me nyuam, network, thiab cov neeg siv kawg. Tab sis nrog kev vam meej thiab kev xav tau ntau ntxiv, Cat7 cables yuav dhau los ua tus qauv yav tom ntej ntawm cov ntaub ntawv chaw thiab cov duab sib txuas.
