Esikhathini sokuqhuma kolwazi, cishe wonke umuntu udinga ukufinyelela ku-inthanethi, futhi cishe yonke indawo ifakwe inethiwekhi kanye nekhebula lenethiwekhi, kodwa ungase ungazi ukuthi nakuba ikhebula lenethiwekhi libukeka lifana, empeleni kunezigaba ezahlukene.Lapha, lesi sihloko sizoqhathanisa ikhebula yenethiwekhi ye-Cat5e (super 5) esetshenziswa kakhulu, ikhebula lenethiwekhi ye-Cat6 (6), ikhebula lenethiwekhi ye-Cat6a (super 6) kanye nekhebula lenethiwekhi ye-Cat7 (7), ukuze ikusize ukhethe intambo yenethiwekhi efanele.
Intambo yenethiwekhi yaziwa nangokuthi i-network jumper kanye ne-twisted pair, ijwayele ukusetshenziswa nge-RJ 45 crystal head, ngoba ishibhile futhi isetshenziswa kabanzi ku-LAN, futhi ikhebula lenethiwekhi liyindlela evamile yokudlulisa izintambo kuzintambo ezihlanganisiwe.
I-Cat5e isebenza ngendlela efanayo nekhebula lenethiwekhi ye-Cat6, yomibili inohlobo olufanayo lwepulaki ye-RJ-45, futhi ingaxhunywa kunoma iyiphi ijekhi ye-Ethernet kukhompuyutha, umzila, noma enye idivayisi efanayo.Nakuba zinokufana okuningi, zinokuhluka okuthile, ikhebula lenethiwekhi ye-Cat5e elisetshenziswa ku-Gigabit Ethernet, ibanga lokudlulisela lifika ku-100m, futhi lingasekela isivinini sokudlulisela esingu-1000Mbps.Izintambo zenethiwekhi ye-Cat6 zinganikeza isivinini sokudlulisela esingafika ku-10 Gbps kumkhawulokudonsa ongu-250 MHz.Ibanga lokudlulisela lentambo yenethiwekhi ye-Cat5e kanye nekhebula lenethiwekhi ye-Cat6 liyi-100m, kodwa uma usebenzisa uhlelo lwe-10 GBASE-T, ibanga lokudlulisela lekhebula lenethiwekhi ye-Cat6 lingafinyelela ku-55 m.Umehluko omkhulu phakathi kwe-Cat5e ne-Cat6 ukusebenza kwezokuthutha.Ikhebuli ye-Cat6 inesihlukanisi sangaphakathi esinciphisa ukuphazamiseka noma i-proximal crosstalk (NEXT).Iphinde ithuthukise i-distal crosstalk (ELFEXT) kunekhebula le-Cat5e, futhi inokulahlekelwa okuphansi kwe-echo nokulahlekelwa kokufaka.Ngakho-ke, ikhebula le-Cat6 linokusebenza okungcono.Ikhebuli yenethiwekhi ye-Cat6 isekela isivinini sokudlulisela esifika ku-10G futhi inomkhawulokudonsa wokuvama ongafika ku-250 MHz, kuyilapho ikhebula lenethiwekhi ye-Cat6a likwazi ukusekela umkhawulokudonsa wemvamisa ofika ku-500 MHz, ophindwe kabili kunentambo yenethiwekhi ye-Cat6.Intambo yenethiwekhi ye-Cat7 isekela i-bandwidth yefrikhwensi efika ku-600 MHz, futhi isekela i-10 GBASE-T Ethernet.Ngaphezu kwalokho, intambo yenethiwekhi ye-Cat7 iwunciphisa kakhulu umsindo we-crosstalk uma iqhathaniswa nekhebula lenethiwekhi ye-Cat6 ne-Cat6a.Ikhebula le-Cat5e Network, ikhebula le-Cat6 kanye nekhebula le-Cat6a linesixhumi se-RJ 45, kodwa isixhumi sekhebula le-Cat7 sikhethekile kakhulu, uhlobo lwaso lwesixhumi yi-GigaGate45 (CG45).Njengamanje, ikhebula le-Cat6 kanye nekhebula le-Cat6a zigunyazwe amazinga e-TIA / EIA, kodwa ikhebula le-Cat7 alivunyelwe.
Intambo yenethiwekhi ye-Cat6 kanye nentambo yenethiwekhi ye-Cat6a zilungele ukusetshenziswa ekhaya.Esikhundleni salokho, uma usebenzisa izinhlelo zokusebenza eziningi, kufanele ukhethe kangcono ikhebula lenethiwekhi ye-Cat7, ngoba ayikwazi ukusekela izinhlelo eziningi kuphela, kodwa futhi ibe nokusebenza okungcono.
Okungenhla kuyincazelo emfushane yomehluko phakathi kwezintambo zenethiwekhi ezivamile.Imikhiqizo yenethiwekhi ye-Shenzhen HDV Phoelectron Technology Co., Ltd. yonke imishini ekhiqizwa eduze kwemikhiqizo yenethiwekhi, kuhlanganisaI-ONUuchungechunge /OLTuchungechunge / optical module uchungechunge / transceiver uchungechunge nokunye.Ukuze wakhe okokusebenza kwenethiwekhi okuhle kakhulu, inkampani yethu ifakwe iqembu locwaningo nentuthuko, ukuze inikeze amakhasimende izinsizakalo zokwesekwa kwezobuchwepheshe ezisezingeni eliphezulu, wamukelekile ukufuna abasebenzi ukuze baqonde imikhiqizo yethu.
