Kodi pali kusiyana kotani pakati pa Ca5e, Cat6, ndi Cat7?

Gulu Lachisanu (CAT5): Mafupipafupi otumizira ndi 100MHz, omwe amagwiritsidwa ntchito potumiza mawu ndi kufalitsa deta ndi mlingo wokwanira wotumizira wa 100Mbps, womwe umagwiritsidwa ntchito mu 100BASE-T ndi 10BASE-T maukonde.Ichi ndiye chingwe cha Ethernet chomwe chimagwiritsidwa ntchito kwambiri.Mtundu uwu wa chingwe kumawonjezera kachulukidwe mapiringidzo ndi malaya apamwamba insulating zakuthupi.Tsopano chingwe cha Gulu 5 sichimagwiritsidwa ntchito kwambiri.

Gulu 5e (CAT5e): The kufala pafupipafupi ndi 100MHz, makamaka ntchito Gigabit Efaneti (1000Mbps).Ili ndi kuchepetsedwa kwakung'ono, kutsika pang'ono, kutsika kwapamwamba ndi chiŵerengero cha crosstalk (ACR) ndi chiŵerengero cha signal-to-noise (Structural Return Loss), ndi zolakwika zazing'ono zochedwa, ndipo ntchitoyo imakhala yabwino kwambiri.M'ma projekiti enieni, ngakhale zingwe za Gulu la 5 zimathanso kufalitsa gigabit, zimangolimbikitsidwa kufalitsa mtunda waufupi wa gigabit.Kutumiza kwa gigabit mtunda wautali kungakhale kosakhazikika.Ichinso ndi vuto wamba mu polojekiti, ndipo n'zosavuta kunyalanyaza.Vutolo.

Gulu Lachisanu ndi chimodzi (CAT6): The kufala pafupipafupi ndi 250MHz, amene ali oyenera ntchito ndi mitengo kufala kuposa 1Gbps, makamaka Gigabit Efaneti (1000Mbps).Gulu la 6 lopindika ndi losiyana ndi Gulu 5 kapena Gulu 5 lopindika kwambiri pamawonekedwe ndi kapangidwe kake, osati chimango chotchingira chokhacho chimawonjezedwa, koma mapeyala anayi opotoka amayikidwa mbali zinayi za chimango cha mtanda motsatana.mkati mwa poyambira, ndipo m'mimba mwake wa chingwe ndi wandiweyani.

Super sikisi kapena 6A (CAT6A): pafupipafupi kufala ndi 200 ~ 250 MHz, pazipita kufala liwiro akhoza kufika 1000 Mbps, makamaka ntchito maukonde gigabit.Gulu la 6e chingwe ndi mtundu wowongoleredwa wa chingwe cha Gulu 6.Ndiwonso chingwe chopotoka chosatetezedwa chotchulidwa mu ANSI/EIA/TIA-568B.2 ndi ISO Gulu 6/Class E.Poyerekeza ndi mbali zina, pali kusintha kwakukulu.

Gulu Lachisanu ndi chiwiri (CAT7): Mafupipafupi otumizira amatha kufikira osachepera 500 MHz ndipo kuchuluka kwa kufalikira kumatha kufika 10 Gbps.Ndizofunika kwambiri kuti zigwirizane ndi kugwiritsa ntchito ndi chitukuko cha teknoloji ya 10 Gigabit Ethernet.Mzerewu ndiye awiri opotoka aposachedwa otetezedwa mu Gulu la ISO 7.

Kusiyana kwakukulu pakati pa mitundu yosiyanasiyana ya waya

Kusiyanitsa 1: Kusiyana kwa kutayika, kusiyana kofunikira pakati pa chingwe cha Gulu 6 ndi Category 5e network cable ndikuchita bwino pankhani ya crosstalk ndi kubwereranso.Ndibwino kuti mugwiritse ntchito zingwe za Category 6 mwachindunji kukongoletsa kunyumba.

Kusiyana 2. Makulidwe a chigawo cha waya ndi osiyana.Chingwe cha waya chamtundu wapamwamba wamtundu wamtundu wachisanu chili pakati pa 0.45mm ndi 0.51mm, ndipo pakati pa chingwe chamtundu wachisanu ndi chimodzi chili pakati pa 0.56mm ndi 0.58mm.Chingwe cha netiweki ndi chokhuthala kwambiri;

Kusiyanitsa 3: Kapangidwe ka chingwe ndi kosiyana.Kunja kwa chingwe chapamwamba chamtundu wamtundu wachisanu chimakhala ndi chizindikiro cha "CAT.5e", ndipo chingwe chamtundu wachisanu ndi chimodzi chimakhala ndi "mtanda" wowonekera kwambiri, ndipo khungu lili ndi "CAT.6" logo.
