Intambo yenethiwekhi

I-Network Cable sisixhobo esithumela ulwazi ukusuka kwisixhobo sothungelwano esinye (esifana nekhompyutha) ukuya kwesinye isixhobo sothungelwano. Lilungu elisisiseko lothungelwano. Kwinethiwekhi yethu yendawo eqhelekileyo, intambo yothungelwano esetyenzisiweyo ikwayintlobo ngeentlobo. Phantsi kweemeko eziqhelekileyo, i-LAN eqhelekileyo ayisebenzisi iintlobo ngeentlobo zeentambo zenethiwekhi ukuqhagamshela izixhobo zenethiwekhi. Kuthungelwano olukhulu okanye uthungelwano lwendawo ebanzi, iintlobo ezahlukeneyo zeentambo zothungelwano zisetyenziselwa ukudibanisa iintlobo ezahlukeneyo zothungelwano kunye.Yeyiphi intambo yothungelwano enokusetyenziswa kufuneka ikhethwe ngokwe-topology yenethiwekhi, imigangatho yesakhiwo senethiwekhi kunye nesantya sothumelo.Ihambisa imiqondiso kwifom iipulse ezikhanyayo kwaye iqulathe imicu ebonakalayo eyenziwe ngeglasi okanye iplastiki ebonakalayo.Ngezantsi kukho intshayelelo malungaIntambo yenethiwekhi.

Njengenxalenye eyimfuneko kubuchwepheshe bonxibelelwano bale mihla, yenza umsebenzi obalulekileyo wokuhanjiswa kwedatha. Ukusukela kwezona ntambo zemfonomfono zakuqala ukuya kwiintsinga zanamhlanje ezixhasa ukuhanjiswa kwedatha ngesantya esiphezulu, iintlobo kunye nobuchwepheshe beentambo zenethiwekhi ziye zaguquka ngendlela emangalisayo.

Intambo yenethiwekhi iqulethe izibini ezine zeengcingo kunye neentsimbi ezisibhozo. Ingundoqo nganye inomahluko wombala kwaye isetyenziselwa ukuhanjiswa kwedatha. Inokusetyenziswa kwiindidi ezahlukeneyo zeemeko kwinkqubo edibeneyo yocingo.

1）Ihlelwa ngokwesihlandlo sokusetyenziswa: inokwahlulwa ibe ziintambo zangaphakathi kunye neentambo zangaphandle. Iintambo zangaphakathi zibhekisela kwiintambo ezisetyenziselwa ukuthumela imiqondiso ngaphakathi kwezakhiwo, njengeentambo zenethiwekhi, iintambo zefowuni kunye neentambo zikamabonwakude. Iintambo zangaphandle zibhekisela kwiintambo ezisetyenziselwa ukuhambisa iimpawu kwiindawo ezingaphandle, ezifana neentambo zokukhanya kunye neentambo ze-coaxial.

2）Ihlelwe nguUlwakhiwo: lunokwahlulwa lube ngambini ejijekileyo engakhuselekanga kunye nesibini esijijekileyo esikhuselekileyo. Isibini esijijekileyo esingakhuselekanga sibhekisa kwisibini esijijekileyo esingenamaleko angaphandle akhuselayo esinyithi, adla ngokusetyenziselwa ukuhambisa imiqondiso ye-analog ngesantya esiphantsi. Isibini esijikiweyo esijikiweyo sibhekisa kwisibini esijijekileyo esinomaleko okhuselayo wesinyithi wangaphandle, odla ngokusetyenziselwa ukuhanjiswa kweempawu zedijithali ngesantya esiphezulu kwaye unomsebenzi olungileyo wokuchasana nokuphazamiseka.

3) I-Classified by interface: I-interface ingahlelwa kwi-RJ-11, i-RJ-45, kunye ne-SC interfaces. I-port ye-RJ-11 isetyenziselwa ukudibanisa imigca yefowuni ye-analog, i-port ye-RJ-45 isetyenziselwa ukudibanisa iintambo ze-Ethernet, kwaye i-SC port isetyenziselwa ukudibanisa iifayili ze-optical.
