Ukuvikela, ikakhulukazi ezintanjeni eziqinile kanye nezintambo ze-ethernet ezivikelwe, kunciphisa ukuphazamiseka okuvela kwezinye izinto zobuchwepheshe, okuqinisekisa ukuthi izinga lakho lokudluliswa kwedatha lihlala lizinzile futhi lishesha.

Ngikhetha kanjani isigaba sekhebula le-Ethernet esifanele?

Khetha ikilasi ngokwejubane elidingekayo kanye nebanga. Emakhaya amaningi, ukusebenzisa izintambo ze-ethernet ze-Cat 5e noma ze-Cat 6 kufanelana kahle. Ukuze uthole inethiwekhi ye-bandwidth ephezulu noma ukusebenza isikhathi eside, cabanga ngezincazelo ze-Cat 6a noma ze-Cat 7.

Yiziphi izinto okufanele ngizibheke kumakhebula e-Ethernet?

Funa izintambo zokubopha ezakhiwe ngocingo lwethusi oluqinile kanye nesivikelo sekhwalithi ephezulu, njengoba lezi zinto ziqinisekisa ukusebenza okuphezulu kanye nokuphila isikhathi eside kwekhebula.

Ingabe ukufakwa okungekuhle kungathinta ukusebenza kahle kwekhebula le-Ethernet?

Kulungile, ukufakwa kabi kwezintambo zenethiwekhi kungaholela ekulahlekelweni noma ekuphazamisekeni kwesignali. Hlonipha njalo ukugoba okubukhali, gcina izintambo kude nezintambo zikagesi, futhi ulandele imikhuba emihle kakhulu yezintambo ze-ethernet.

Ingabe izintambo ezibiza kakhulu zihlala zingcono?

Akunjalo ngempela. Cabanga ngezidingo zenethiwekhi yakho kuqala. Izintambo ezibizayo, njengezintambo eziqinile noma izintambo zokuxhuma, zingase zibe nezici ezinhle, kodwa awuzidingi ukuze zisetshenziswe kalula.

Ngingahlola kanjani ukuthi ikhebula lami le-Ethernet lisebenza kahle?

Zama ikhebula le-RJ45 elinomshini wokuhlola ikhebula lenethiwekhi noma ngokuxhuma amadivayisi ngqo. Sesha uxhumano oluzinzile kanye nesivinini se-gigabit ukuze uqinisekise.
