Intambo yenethiwekhi, eyaziwa nangokuthi ikhebula yedatha noma ikhebula lenethiwekhi, isebenza njengendawo yokudlulisa ulwazi kusuka kudivayisi yenethiwekhi eyodwa (efana nekhompyutha) iye kwenye.Iyingxenye ebalulekile neyisisekelo yanoma iyiphi isistimu yenethiwekhi, evumela ukudluliswa kwedatha nokuxhumana phakathi kwamadivaysi.
1.Izinhlobo zamakhebuli enethiwekhi:
Ikhebula Elipheya Elisontiwe (UTP/STP):
Uhlobo oluvame ukusetshenziswa kakhulu lwekhebuli yenethiwekhi.
Iqukethe amapheya amane ezintambo zethusi ezisontelwe ndawonye ukuze kuncishiswe ukuphazamiseka kukazibuthe.
I-Unshielded Twisted Pair (UTP) iwuhlobo oluvame kakhulu, kuyilapho iShielded Twisted Pair (STP) inikeza ukuvikeleka okwengeziwe ekuphazamisekeni.
Ifanele ukudluliswa kwebanga elifushane, okuvame ukusetshenziswa kuma-Local Area Networks (LANs).
2.Ikhebuli ye-Coaxial:
Idizayinelwe nge-copper noma i-aluminium core ezungezwe ungqimba oluvikelayo olubambayo kanye nezinto ezivalekile.
Iyakwazi ukuthwala amasignali anamaza aphezulu, asetshenziswa kakhulukazi amasiginali kamabonakude we-analogi kanye nolunye uxhumano lwe-inthanethi ye-broadband.
Akuvamile kakhulu kunethiwekhi yesimanje ngenxa yokukhuphuka kwamasignali edijithali nezintambo ze-fiber optic.
3.Ikhebula le-Fiber Optic:
Yenziwe ngengilazi noma ngemicu yepulasitiki edlulisa idatha kusetshenziswa ama-pulses okukhanya.
Inikeza umkhawulokudonsa ophezulu, ukudluliselwa kwebanga elide nokulahlekelwa kwesignali okuncane.
Ilungele ukuxhumana kwenethiwekhi okunomgogodla kanye nohambo olude.
Izici Nezinzuzo Zezintambo Zenethiwekhi:
Ukuvumelana nezimo: Izintambo zenethiwekhi zingahanjiswa kalula futhi zifakwe ezindaweni ezihlukahlukene.
Ukusebenza Kwezindleko: Amakhebuli amabili asontekile, ikakhulukazi i-UTP, awabizi futhi atholakala kabanzi.
Ukuqina: Amanethiwekhi anganwetshwa kalula ngokungeza izintambo namadivayisi engeziwe.
Ukuqina: Izintambo zenethiwekhi zenzelwe ukuthi zimelane nokuguga, ziqinisekise ukuxhumana okuthembekile.
Amazinga Nezicaciso:
Izintambo zenethiwekhi zithobelana namazinga emboni ahlukahlukene, njenge-EIA/TIA 568A kanye ne-568B, acacisa ukumiswa kwezintambo kanye nephinikhodi yezintambo.
Izigaba ezihlukene zamakhebuli (Ikati 5, Ikati 5e, Ikati 6, njll.) zinikeza amazinga ahlukahlukene okusebenza, okuhlanganisa umkhawulokudonsa, imvamisa, nesivinini sokudlulisela.
Kafushane, izintambo zenethiwekhi zidlala indima ebalulekile ekuxhumaniseni amadivayisi nasekunikeni amandla ukuxhumana kwedatha ngaphakathi kwenethiwekhi.Ukukhethwa kohlobo lwekhebula kuncike ezidingweni ezithile zenethiwekhi, okuhlanganisa umkhawulokudonsa, ibanga lokudlulisela, nokucatshangelwa kwezindleko.
