[AipuWaton] Ukuqonda Izintambo Eziyisishiyagalombili Kuzintambo Ze-Ethernet: Imisebenzi Nemikhuba Engcono Kakhulu

Ukuxhuma izintambo zenethiwekhi ngokuvamile kungase kudide, ikakhulukazi uma uzama ukuthola ukuthi yiziphi izintambo eziyisishiyagalombili zethusi ezingaphakathi kwekhebula ye-Ethernet ezibalulekile ukuze kuqinisekiswe ukudluliswa kwenethiwekhi okuvamile. To clarify this, it is important to understand the overall function of these wires: they are designed to reduce electromagnetic interference (EMI) by twisting pairs of wires together at specific densities. This twisting allows the electromagnetic waves produced during the transmission of electrical signals to cancel each other out, effectively eliminating potential interference. The term "twisted pair" aptly describes this construction.

Amapheya asontekile ekuqaleni ayesetshenziselwa ukudlulisa amasignali ocingo, kodwa ukusebenza kwawo kwaholela ekwamukelweni kwawo kancane kancane ekudluliseleni isignali yedijithali. Currently, the most widely used types are Category 5e (Cat 5e) and Category 6 (Cat 6) twisted pairs, both capable of achieving bandwidths of up to 1000 Mbps. Kodwa-ke, umkhawulo obalulekile wamakhebuli amabili asontekile yibanga lawo eliphakeme kakhulu lokudlulisela, ngokuvamile elingeqi amamitha ayi-100.

Kubalulekile ukuqaphela ukuthi ukubamba ngekhanda i-oda le-T568A akudingekile uma kubhekwa ukuncipha kokuvama kwalo. Uma kudingeka, ungakwazi ukufeza leli zinga ngokushintsha izintambo 1 no-3 no-2 ngezingu-6 ngokusekelwe ekucushweni kwe-T568B.

Kuzinhlelo zokusebenza ezijwayelekile ezisebenzisa amapheya asontekile eSigaba 5 kanye Nesigaba 5e, amapheya amane ezintambo—ngaleyo ndlela, ingqikithi yezintambo eziyisishiyagalombili eziphelele—ngokujwayelekile zisetshenziswa. For networks operating under 100 Mbps, the usual configuration involves using wires 1, 2, 3, and 6. The common wiring standard, known as T568B, arranges these wires at both ends as follows:

1A
2B

I-oda le-T568B Wiring:

  • Iphinikhodi 1: okuwolintshi-okumhlophe
  • Iphinikhodi 2: owolintshi
  • Iphinikhodi 3: oluhlaza-omhlophe
  • Iphinikhodi 4: blue
  • Iphinikhodi 5: blue-white
  • Iphini 8: nsundu

 

I-oda le-T568A Wiring:


Iphinikhodi 2: eluhlaza

Iphinikhodi 4: blue
Iphinikhodi 5: blue-white
Iphinikhodi 6: i-orange
Iphinikhodi 7: brown-white

Iphini 8: nsundu

Ukuze uqonde kangcono ukuthi kungani izintambo 1, 2, 3, no-6 zisetshenziswa, ake sibheke izinjongo ezithile zomongo ngamunye:

Ukubaluleka Kokuminyana Okubili Okusontekile kanye Nokuvikela

Imibono Eyiphutha Evamile

Akuvamile ukuzwa abantu bethi, "Ngincamela ukusebenzisa ilungiselelo lami lapho ngenza izintambo; ingabe kuyamukeleka lokho?" While there may be some flexibility for personal use at home, it is highly advisable to follow established wiring orders in professional or critical scenarios. Deviating from these standards could undermine the effectiveness of twisted pair cables, leading to significant data transmission loss and reduced transmission distance.
