Mararka qaarkood macaamiisha qaar ayaa weydiin doona waa maxay farqiga u dhexeeya dekedda korantada iyo dekedda indhaha ee warshadaha Ethernet switch, maxay u kala duwan yihiin dekedda indhaha iyo dekedda korontada, maxayse ku kala duwan yihiin shaqadooda? Ujeeddada dhibaatooyinkan ee dekedaha indhaha iyo korantada ee furayaasha Ethernet-ka ee warshadaha, aan si wadajir ah uga wada hadalno.

Ugu horreyntii, waxaan u baahannahay inaan si cad u fahanno waxa ay tahay dekedda indhaha iyo dekedda korontada. Dekadda indhaha ee isweydaarsiga Ethernet-ka ee warshadaha waxaa loola jeedaa dekedda indhaha waxaa loola jeedaa interface fiber optic, oo leh tilmaamo sida hal-mode, multi-mode, Gigabit, iyo 100M. Dekadaha indhaha ee shixnado warshadeed guud ahaan waa la isku lammaaniyay, hal TX dirid dhammaad ah iyo hal RX oo dhammayn ah. Nooca dekedda ee 100M beddelka guud ahaan waa kaarka SC oo leh deked laba jibbaaran, dekedda indhaha ee Gigabit waa guud ahaan moduleka indhaha ee SFP, nooca dekedduna waa LC. Dekadda korontadu sidoo kale waa dekedda RJ45, dekedda (fiilada shabakadda) ee ku xirta lammaanaha qalloocan, heerka guud waa 10M ama 100M, taas oo ah 100M wareejinta warshadaha, qaarna waxay taageeraan 1000M, taas oo ah Gigabit beddelka.

Dhab ahaantii, ujeedada dekedda indhaha iyo dekedda korantada ee wareejinta Ethernet warshadaha waa isku mid, labadaba gudbinta. Masaafada ugu badan ee dekedda korontadu waa 100 mitir, dekedda indhaha waxay gaari kartaa 5KM ilaa 100KM iyadoo ku xiran nooca fiber-ka. Sidaa darteed, korontada guud ahaan waxaa loo isticmaalaa isticmaalka caadiga ah, iyo fiber indhaha u dhigma ayaa loo doortay gudbinta fogfog.
