[Aipuwaton] Ukuqonda ibanga eliphakeme lokuhambisa lobuchwepheshe be-poe ubuchwepheshe

Ubuchwepheshe be-Ethernet (Poe) Ubuchwepheshe buguqukile ngendlela esiyifaka ngayo amadivaysi enethiwekhi ngokuvumela womabili amandla nedatha ukuthi idluliselwe ngaphezulu kwe-Ethernet Calling ejwayelekile. Kodwa-ke, abasebenzisi abaningi bayazibuza ukuthi ibanga lokuhambisa eliphakeme le-poe liyini. Ukuqonda izici ezithonya leli banga kubalulekile ekuhlelweni kwenethiwekhi okusebenzayo kanye nokwenza.

Yini enquma ibanga eliphezulu le-poe?

Into ebucayi ekunqumeni ibanga eliphezulu le-poe yikhwalithi nohlobo lwekhebula elisontekile elisetshenzisiwe. Amazinga ajwayelekile angenakuqhathaniswa afaka:

Shanghai-aipu-wamon-electronic-Industries-Co-Ltd-

Isigaba 5 (Cat 5)

Isekela ijubane kuze kube yi-100 MBPS

Isigaba 5E (ikati 5E)

Uhlobo oluthuthukisiwe ngokusebenza okungcono, futhi lusekela ama-MBP ayi-100.

Isigaba 6 (Cat 6)

Iyakwazi ukuphatha ijubane kuze kufike ku-1 gbps.

Kungakhathalekile ukuthi luhlobo lwekhebula, amazinga ezimboni asungula ibanga eliphakeme lokuhambisa elisebenzayo lamamitha ayi-100 (amamitha angama-328) ngokuxhumeka kwedatha ngaphezulu kwamakheshana e-Ethernet. Lo mkhawulo ubalulekile ukuze ulondoloze ubuqotho bedatha kanye nokuqinisekisa ukuxhumana okuthembekile.

Isayensi ngemuva komkhawulo wamamitha ayi-100

Lapho udlulisa amasiginali, asontekile amakhamera amakhamera wokumelana kanye nokuqina kwe-capacitance, okungaholela ekuwohlokeni kwesiginali. Njengesiginali ithatha ikhebula, ingangena:

:

Ukulahleka kwamandla wesiginali ngaphezulu kwebanga.

Ukuhlanekezela:

Ukuguqulwa ku-wavelform ye-wavelform, ukuthembeka kwedatha.

Lapho ikhwalithi yesiginali inciphisa ngaphezu komkhawulo owamukelekayo, ithinta amanani okuhambisa aphumelelayo futhi ingaholela ekulahlekelweni kwedatha noma amaphutha ephakethe.

Ukubala ibanga lokuhambisa

Okwe-100base-TX, osebenza kuma-MBP ayi-100, isikhathi sokudlulisela idatha eyodwa, eyaziwa ngokuthi yi- "Time Time," ibalwa kanjena:

[\ umbhalo {kancane isikhathi} = \ frac {1} {100, \ {{mbps}}}}}}}

Le ndlela yokuhambisa isebenzisa i-CSMA / CD (I-Carrier Courler Sense Ukufinyelela okuningi ngokutholwa kokushayisana), okuvumela ukutholwa okusebenzayo kokutholwa kumanethiwekhi abiwe. Kodwa-ke, uma ubude bentambo budlula amamitha ayi-100, amathuba okuthola ukushayisana anciphise, ebeka engcupheni ukulahleka kwedatha.

Kubalulekile ukuqaphela ukuthi ngenkathi ubude obukhulu bubekwe kumamitha ayi-100, izimo ezithile zingavumela ukuguquguquka okuthile. Isivinini esiphansi, ngokwesibonelo, linganwebeka amabanga asetshenzisiwe aze afike kumamitha ayi-15-200, kuya ngekhwalithi yekhebula kanye nezimo zenethiwekhi.

Izincomo zobude obusebenzayo bekhebula

Ekufakweni kwangempela komhlaba, ukunamathela ngokuqinile emkhawulweni wamamitha ayi-100 kuyalulekwa. Kodwa-ke, ochwepheshe abaningi benethiwekhi batusa ukugcina ibanga lamamitha angama-80 kuye kwangama-90 ukuqinisekisa ukuthembeka futhi kunciphise noma yiziphi izingqinamba zekhwalithi ezingaba khona. Le margin yokuphepha isiza ukwamukela ukuhlukahluka ngekhwalithi yekhebula nezimo zokufaka.

Ngenkathi izintambo ezisezingeni eliphakeme kwesinye isikhathi zingadlula umkhawulo wamamitha ayi-100 ngaphandle kwezinkinga ezisheshayo, le ndlela ayinconywa. Izinkinga ezingaba khona zingabonakala ngokuhamba kwesikhathi, ziholele ekuphazamisweni kwenethiwekhi okubalulekile noma ukusebenza okunganele ngemuva kokuthuthuka.

Ukugcina

Ukufingqa, ibanga eliphakeme lokuhambisa lobuchwepheshe be-poe lithonywa ngokuyinhloko isigaba sezintambo ezisontekile ezisomile kanye nokulinganiselwa ngokomzimba kokudluliselwa kwesiginali. Umkhawulo wamamitha ayi-100 uyasungulwa ukusiza ukugcina ubuqotho bedatha nokwethenjwa. Ngokulandela imikhuba yokufaka enconyiwe futhi uqonde izimiso eziyisisekelo zokudluliselwa kwe-Ethernet, ochwepheshe benethiwekhi bangaqinisekisa ukusebenza kwenethiwekhi okuqinile nokusebenza kahle.
