Ndeupi musiyano uripo pakati peCa5e, Cat6, uye Cat7?

Chikamu Cheshanu (CAT5): Iyo frequency yekufambisa ndeye 100MHz, inoshandiswa pakufambisa kwezwi uye kutumira data ine mwero wepamusoro wekutapurirana we100Mbps, inonyanya kushandiswa mu100BASE-T uye 10BASE-T network.Iyi ndiyo inonyanya kushandiswa Ethernet tambo.Rudzi urwu rwetambo runowedzera density yemhepo uye inopfeka emhando yepamusoro insulating material.Ikozvino iyo Chikamu 5 tambo haina kunyanya kushandiswa zvakanyanya.

Category 5e (CAT5e): Iyo yekufambisa frequency ndeye 100MHz, inonyanya kushandiswa kuGigabit Ethernet (1000Mbps).Iyo ine diki attenuation, kushoma crosstalk, yakakwirira attenuation uye crosstalk ratio (ACR) uye chiratidzo-kune-ruzha chiyero (Structural Return Loss), uye kudiki kunonoka kukanganisa, uye kuita kwakagadziridzwa zvakanyanya.Mumapurojekiti chaiwo, kunyangwe Category 5 tambo dzinogona zvakare kutumira gigabit, inongokurudzirwa kupfupi-kure gigabit kutapurirana.Kureba-kure gigabit kutapurirana kunogona kunge kusina kugadzikana.Iyi zvakare imhosva yakajairika muprojekiti, uye zviri nyore kufuratira.Dambudziko.

Category Six (CAT6): The transmission frequency is 250MHz, iyo inonyanya kukodzera kune maapplication ane transmission rates yakakwirira kupfuura 1Gbps, kunyanya yeGigabit Ethernet (1000Mbps).Chikamu 6 chakamonyoroka peya chakasiyana neChikamu 5 kana Chikamu 5 chepamusoro chakamonyaniswa pachitarisiko uye chimiro, kwete chete insulating muchinjiko furemu inowedzerwa, asi mapaya mana epairi akamonyoroka anoiswa pamativi mana emuchinjikwa zvakateerana.mukati me groove, uye dhayamita yetambo zvakare yakakura.

Super nhanhatu kana 6A (CAT6A): iyo frequency yekufambisa ndeye 200 ~ 250 MHz, iyo yakanyanya kutapurirana kumhanya inogona zvakare kusvika 1000 Mbps, inonyanya kushandiswa mumagigabit network.Chikamu 6e tambo ishanduro yakagadziridzwa yeChikamu 6 tambo.Iyo zvakare isina kuvharidzirwa yakamonyoroka tambo yakatsanangurwa mu ANSI/EIA/TIA-568B.2 uye ISO Chikamu 6/Kirasi E zviyero.Zvichienzaniswa nezvimwe zvinhu, pane kuvandudzika kukuru.

Category Seven (CAT7): Iyo frequency yekufambisa inogona kusvika pa500 MHz uye mwero wekutapurirana unogona kusvika 10 Gbps.Iyo inonyanya kuenderana nekushandiswa uye kusimudzira kwegumi Gigabit Ethernet tekinoroji.Mutsetse uyu ndiyo yazvino yakadzivirirwa yakamonyoroka peya muISO Chikamu 7.

Musiyano mukuru pakati pemhando dzakasiyana dzewaya

Musiyano 1: Musiyano mukurasikirwa, mutsauko wakakosha pakati peChikamu 6 tambo uye Chikamu 5e network tambo ndiyo yakagadziridzwa mashandiro maererano necrosstalk uye kurasikirwa kwekudzoka.Inokurudzirwa kushandisa Category 6 network cables zvakanangana nekushongedza imba.

Kusiyana 2. Ukobvu hwetambo yetambo yakasiyana.Waya musimboti weiyo super shanu mhando network tambo iri pakati pe0.45mm ne0.51mm, uye waya yepakati yemhando nhanhatu network tambo iri pakati pe0.56mm ne0.58mm.Iyo network tambo yakanyanya kukora;

Musiyano 3: Chimiro chetambo chakasiyana.Kunze kweiyo super five-type network cable ine "CAT.5e" logo, uye tambo yemhando nhanhatu ine "cross frame" inooneka, uye ganda rine "CAT.6" logo.
