Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Izinhlobo ezivamile zezintambo zenethiwekhi
1. Ikhebula yenethiwekhi yesigaba 5e (CAT5e).
Intambo yenethiwekhi yesigaba 5e isekela isivinini sokudlulisa se-Ethernet esingu-100Mbps kanye nemvamisa yokudlulisela efika ku-100MHz. Ngokuvamile ingahlangabezana nezidingo eziningi zansuku zonke zokufinyelela ku-inthanethi futhi isetshenziswa kabanzi kumanethiwekhi asekhaya.
2. Ikhebula yenethiwekhi yesigaba 6 (CAT6).
Ikhebuli yenethiwekhi yesigaba sesi-6 isekela isivinini sokudlulisa se-Ethernet esingu-1Gbps (gigabit) kanye nemvamisa yokudlulisela efika ku-250MHz. Ingamelana kangcono nokuphazamiseka kwe-crosstalk kanye nozibuthe kagesi, futhi inikeze ukudluliswa kwedatha okuzinzile nokushesha kakhudlwana.
3. Ikhebula yenethiwekhi yesigaba 6a (CAT6a).
Ikhebula lenethiwekhi lesigaba 6a ngokwethiyori lisekela isivinini sokudlulisela esingu-10Gbps kanye nomkhawulokudonsa wefrikhwensi ongu-500MHz. Ngokucaciswa okuqinile namazinga, inganikeza ikhono elingcono lokulwa nokuphazamiseka kanye namandla aphezulu omkhawulokudonsa.
4. Ikhebuli yenethiwekhi yeSigaba 7 (CAT7).
Ikhebuli yenethiwekhi yesigaba sesi-7 ngokwethiyori isekela izinga lokudlulisela elingu-10Gbps kanye nomkhawulokudonsa wokuvama ongu-600MHz. Ingahlinzeka ngekhwalithi ephezulu yokudlulisa isignali kanye nekhono lokulwa nokuphazamiseka. Ngenxa yentengo yayo ephezulu nokusebenza ngokweqile, izintambo zeSigaba 7 azisetshenziswa kakhulu ezindlini njengamanje.
Izidingo neziphakamiso zokusebenzisa izintambo zenethiwekhi
Ubude bekhebula lenethiwekhi: Ngokwethiyori, izintambo zenethiwekhi ye-CAT5e, i-CAT6 ne-CAT6a zingasekela ibanga lokudlulisela elingamamitha angu-100, kodwa kunconywa ukusebenzisa izintambo zenethiwekhi zamamitha amafushane uma uzisebenzisa ukuze kuqinisekiswe ukusebenza kokudluliselwa kwezintambo zenethiwekhi.
Indawo yezintambo: Uma usebenzisa izintambo zenethiwekhi, zama ukubeka amadivayisi enethiwekhi njengamarutha ezindaweni ezifanele ukuze unciphise ubude bezintambo zenethiwekhi nobunkimbinkimbi bezintambo, futhi uqinisekise ukumbozeka nokuzinza kwenethiwekhi.
Avikelekile futhi angavikelwe: Izintambo zenethiwekhi ezivikelwe zinesendlalelo esiyisivikelo esengeziwe kanye nokusebenza okuhle kokulwa nokuphazamiseka; izintambo zenethiwekhi ezingavinjiwe zinezindleko eziphansi futhi ziyavumelana nezimo ukuzifaka, ezingahlangabezana nezidingo zansuku zonke. Uma kunezinkinga zokuphazamiseka kazibuthe endaweni yokusetshenziswa, izintambo zenethiwekhi ezivikelekile zingakhethwa.
Ukuthuthukiswa nokugcinwa: Uxhumo lwekhebula lenethiwekhi lungahlolwa njalo ukuze kuqinisekiswe ukuzinza nokuphepha kwenethiwekhi; uma kungenzeka ukuthi kuthuthukiswe inethiwekhi esikhathini esizayo kucatshangelwa, izintambo zenethiwekhi zeSigaba 6 noma zeSigaba sesi-7 zingakhethwa.
Kubasebenzisi abaningi, izintambo zenethiwekhi zeSigaba 5 noma zeSigaba 6 sezingakwazi ukuhlangabezana nezidingo zansuku zonke. Uma kukhona abasebenzisi abanezidingo zokuhlangenwe nakho okuphezulu kwenethiwekhi noma ukudluliswa kwedatha enesivinini esikhulu, izintambo zenethiwekhi zeSigaba 6 noma Isigaba 7 noma izintambo zenethiwekhi zeSigaba 8 zingacatshangelwa.
