M'munda wa kulankhulana maukonde, pankhani Efaneti zingwe, nthawi zambiri amatchulidwa kuti pali wapamwamba mitundu isanu ya zingwe maukonde, sikisi mitundu ya zingwe maukonde, ndi mitundu isanu ndi iwiri ya zingwe maukonde.M'zaka zaposachedwa, zingwe zapaintaneti za Cat8 Class 8 zatchulidwanso kwambiri.Chingwe chaposachedwa cha Cat8 Class 8 network ndi m'badwo waposachedwa kwambiri wodumphira wotetezedwa kawiri (SFTP), womwe uli ndi ma siginecha awiri omwe atha kuthandizira bandwidth ya 2000MHz ndi liwiro lotumizira mpaka 40Gb/s.Komabe, mtunda wake waukulu wotumizira ndi 30m chabe, motero umagwiritsidwa ntchito polumikiza ma seva, masiwichi, mafelemu ogawa, ndi zida zina m'malo amfupi a data.Pakali pano, pali mitundu isanu wamba wa zingwe maukonde pa msika: wapamwamba zingwe zisanu maukonde, zingwe zisanu ndi chimodzi maukonde, wapamwamba sikisi zingwe maukonde, zingwe zisanu ndi ziwiri maukonde, ndi wapamwamba zingwe zisanu ndi ziwiri maukonde.Zingwe zapaintaneti za Cat8 Gawo 8, monga zingwe za netiweki za Gulu 7/Ultra Category 7, zonse ndi zingwe zopindika zotchingidwa ndipo zitha kugwiritsidwa ntchito m'malo opangira ma data, madera othamanga kwambiri, komanso bandwidth.Ngakhale mtunda wotumizira wa zingwe zapaintaneti za Cat8 Gulu la 8 silotalikirana ndi zingwe zapaintaneti za Gulu 7/Ultra Category 7, liwiro lawo ndi ma frequency ndi apamwamba kwambiri kuposa a Category 7/Ultra Category 7 network zingwe.Pali kusiyana kwakukulu pakati pa zingwe zapaintaneti za Cat8 Category 8 ndi zingwe zapaintaneti za Super Category 5, komanso zingwe zapaintaneti za Gulu 6/Super Category 6, zomwe zimawonetsedwa kwambiri ndi liwiro, ma frequency, mtunda wotumizira, ndi kugwiritsa ntchito.
Chingwe cha Gulu 1 (CAT1): Chingwe chapamwamba kwambiri cha bandwidth ndi 750kHz, chomwe chimagwiritsidwa ntchito ngati ma alarm, kapena kungotumiza mawu (Miyezo ya Gulu 1 imagwiritsidwa ntchito makamaka pazingwe zamafoni asanafike zaka za m'ma 1980), mosiyana ndi kutumiza deta.
CAT2: Chingwe chapamwamba kwambiri cha bandwidth ndi 1MHZ, chomwe chimagwiritsidwa ntchito potumiza mawu ndi kutumiza deta ndi mlingo wapamwamba kwambiri wa 4Mbps.Amagwiritsidwa ntchito kwambiri pamakina akale omwe amagwiritsa ntchito 4MBPS Token pass protocol.
CAT3: imatanthawuza chingwe chofotokozedwa mumiyezo ya ANSI ndi EIA/TIA568 pakadali pano.Mafupipafupi kufala kwa chingwe ichi ndi 16MHz, ndipo pazipita mlingo kufala ndi 10Mbps (10Mbit/s).Amagwiritsidwa ntchito kwambiri m'mawu, 10Mbit / s Efaneti (10BASE-T) ndi 4Mbit / s Chizindikiro cha mphete.Kutalika kwakukulu kwa gawo la netiweki ndi 100m.Zolumikizira zamtundu wa RJ zimagwiritsidwa ntchito, zomwe zazimiririka pamsika.

CAT3: imatanthawuza chingwe chofotokozedwa mumiyezo ya ANSI ndi EIA/TIA568 pakadali pano.Mafupipafupi kufala kwa chingwe ichi ndi 16MHz, ndipo pazipita mlingo kufala ndi 10Mbps (10Mbit/s).Amagwiritsidwa ntchito kwambiri m'mawu, 10Mbit / s Efaneti (10BASE-T) ndi 4Mbit / s Chizindikiro cha mphete.Kutalika kwakukulu kwa gawo la netiweki ndi 100m.Zolumikizira zamtundu wa RJ zimagwiritsidwa ntchito, zomwe zazimiririka pamsika.Category 4 chingwe (CAT4): pafupipafupi kufala kwa mtundu uwu wa chingwe ndi 20MHz, amene ntchito kufala mawu ndi kufala deta ndi mlingo wapamwamba kufala 16Mbps (kutanthauza 16Mbit/s Chizindikiro mphete).Imagwiritsidwa ntchito makamaka pazithunzi zochokera ku LAN ndi 10BASE-T/100BASE-T.Kutalika kwakukulu kwa gawo la netiweki ndi 100m.Zolumikizira zamtundu wa RJ zimagwiritsidwa ntchito, zomwe sizigwiritsidwa ntchito kwambiri
CAT5: Chingwe chamtunduwu chachulukitsa kachulukidwe ka ma Linear kachulukidwe ndipo chimakutidwa ndi zida zapamwamba zotchingira.The pazipita pafupipafupi bandiwifi ya chingwe ndi 100MHz, ndi pazipita mlingo kufala ndi 100Mbps.Imagwiritsidwa ntchito potumiza mawu komanso kutumizirana ma data ndi liwiro lalikulu kwambiri la 100Mbps.Amagwiritsidwa ntchito makamaka pa 100BASE-T, ndipo kutalika kwa gawo la maukonde ndi 100m.Zolumikizira zamtundu wa RJ zimagwiritsidwa ntchito.Ichi ndi chingwe cha Efaneti chomwe chimagwiritsidwa ntchito kwambiri mkati mwa chingwe chopotoka, chokhala ndi mawiri osiyanasiyana okhala ndi utali wosiyanasiyana.Nthawi zambiri, nthawi yokhota ya mapeyala anayi opotoka imakhala mkati mwa 38.1mm, yopindika mozungulira, ndipo kutalika kwa peyala imodzi kumakhala mkati mwa 12.7mm.
CAT5e: CAT5e ili ndi kutsika pang'ono, kutsika kwapang'onopang'ono, kutsika kwambiri kwa crosstalk ratio (ACR), kutayika kwapang'onopang'ono, ndi zolakwika zazing'ono zochedwa, kuwongolera kwambiri magwiridwe antchito.Zingwe za Super Class 5 zimagwiritsidwa ntchito kwambiri pa gigabit Ethernet (1000Mbps)
