Amasongo okushelela okuqhuba angahlukaniswa abe yizindandatho zokushelela okuqhuba i-mercury, izindandatho zokushelela okuqhuba i-optical fiber, izindandatho zokushelela okuqhuba inethiwekhi, izindandatho zokushelela okuqhuba i-high current, njll. ngokwendlela ezidlulisa ngayo. Phakathi kwazo, izindandatho zokushelela okuqhuba i-optical fiber zingahlukaniswa zibe yizindandatho zokushelela okuqhuba i-optical fiber ezinesiteshi esisodwa kanye nezindandatho zokushelela okuqhuba i-optical fiber ezineziteshi eziningi, kanti izindandatho zokushelela okuqhuba inethiwekhi zingahlukaniswa zibe yi-Gigabit kanye ne-100M. Mhlawumbe abantu abaningi bazobuza, okufanayo yindandatho yokushelela okuqhuba inethiwekhi, ngakho-ke uyini umehluko phakathi kwezindandatho zokushelela okuqhuba i-Gigabit kanye ne-100M? Namuhla ngizokutshela ngomehluko phakathi kwezindandatho zokushelela okuqhuba i-Gigabit kanye ne-100M.
Izindandatho zokushelela eziqhuba inethiwekhi zibizwa nangokuthi izindandatho zokushelela ze-Ethernet. Izindandatho zokushelela ze-Ethernet zenzelwe ngokukhethekile izimpawu zemvamisa ze-250MHz futhi zenzelwe ukudlulisa izimpawu ze-Ethernet ze-100M/1000M. Zinezinzuzo zokudluliswa okuzinzile, akukho ukulahleka kwephakethe, akukho ikhodi yentambo, ukulahleka okuncane kokubuya, ukulahleka okuncane kokufakwa, ikhono eliqinile lokulwa nokuphazamiseka, kanye nokusekelwa kwe-POE. Phakathi kwazo, umehluko omkhulu phakathi kwezindandatho zokushelela eziqhuba i-100M kanye nezindandatho zokushelela eziqhuba i-Gigabit iphuzu yizivinini zokudlulisa ezahlukene. Njengenethiwekhi yethu yasekhaya, isivinini sokudlulisa senethiwekhi ye-Gigabit ngokuqinisekile siphakeme kakhulu kunesenethiwekhi ye-100M.
Kubonakala sengathi umehluko olula nje ngesivinini sokudlulisa inethiwekhi, kodwa kubakhiqizi bethu bendandatho yokushelela, umehluko omkhulu kakhulu. Okokuqala, izindandatho zokushelela zenethiwekhi ye-100M ngokuvamile zidlulisa izintambo zenethiwekhi ye-100M ezine-core, kanti izindandatho zokushelela zenethiwekhi ye-Gigabit ngokuvamile zidlulisa izintambo zenethiwekhi ye-Gigabit ezine-core, kodwa ngokwenani lezintambo ezidluliswayo, izindandatho zokushelela zenethiwekhi ye-Gigabit zisezinhlangothini zombili zezindandatho zokushelela zenethiwekhi ye-100M. Okwesibili, inethiwekhi ye-Gigabit ngokuvamile isetshenziswa emishinini emikhulu yezimboni, futhi ngokuvamile kunemithombo enamandla yokuphazamiseka kwesignali emishinini, ngakho izindandatho zokushelela zenethiwekhi ye-Gigabit ngokuvamile zidinga ukucutshungulwa kokuvikela isignali yangaphandle. Izindlela ezivamile zalokhu kucubungula ukwengeza izintambo zokuvikela ngaphakathi kwenethiwekhi ye-Gigabit.
Ngokuvamile, izindandatho zokushelela zenethiwekhi ye-100M kanye nezindandatho zokushelela zenethiwekhi ye-Gigabit kungathiwa ziyizinhlelo ezimbili ezihlukene ngokuphelele zezindandatho zokushelela zenethiwekhi, ngoba indawo kanye nemishini esetshenziswa yilaba ababili kuhlukile, futhi izidingo zobuchwepheshe kanye nezidingo zokusetshenziswa kwezindandatho zokushelela zenethiwekhi zihlukile, ngakho-ke umehluko phakathi kwalaba ababili ungashiwo ukuthi mkhulu kakhulu. Ngamafuphi, izidingo zezindandatho zokushelela zenethiwekhi zisekelwe ezidingweni ezithile zamakhasimende. Sizokwenza uhlobo lwezindandatho zokushelela zenethiwekhi ezidingwa yimishini yekhasimende.
