Iindidi zeCable eziphothiweyo: Funda malunga neentlobo ezahlukeneyo
I-twisted pair cable luhlobo oluqhelekileyo lwe-wiring olusetyenziswa kuthungelwano lwe-telecommunications kunye ne-computer. Ziquka izibini zeengcingo zobhedu ezigqunyiweyo ezijijelwe kunye ukunciphisa uphazamiseko lombane. Kukho iintlobo ezininzi ze-twisted pair cable, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa.
Enye yezona ntlobo zixhaphakileyo zeentambo eziphothiweyo yintambo ephothiweyo engakhuselekanga (UTP). Olu hlobo lwekhebula lusetyenziswa kakhulu kwi-Ethernet kunye neenkqubo zefowuni. Iyabiza kwaye kulula ukuyifaka, iyenza ibe lukhetho oludumileyo kwizicelo ezininzi. Iintambo ze-UTP ziza kwiindidi ezininzi, ezifana ne-Cat 5e, i-Cat 6, kunye ne-Cat 6a, nganye inika amanqanaba ahlukeneyo okusebenza kunye ne-bandwidth.
Olunye uhlobo lwentambo ephothiweyo yintambo ejikiweyo ekhuselweyo (STP). Iintambo ze-STP zinezikhuselo ezongezelelweyo zokuthintela ukuphazamiseka kwe-electromagnetic, zizenza zilungele iindawo ezinamanqanaba aphezulu engxolo yombane. Ngokuqhelekileyo zisetyenziswa kwiindawo zoshishino kunye neendawo apho ukhuseleko olongezelelweyo malunga nokuphazamiseka lufunekayo.
Ukongeza, kukho izibini ezijijekileyo ezenzelwe ngokukodwa ukusetyenziswa kwangaphandle, njengezibini eziphothiweyo zangaphandle. Yenziwe kwizinto ezinokumelana neendawo ezinzima, ezi ntambo zifanelekile ukufakwa kwangaphandle, njengokudibanisa izakhiwo okanye iinkqubo zokujonga ngaphandle.
Xa ukhetha i-twisted pair cable echanekileyo kwisicelo esithile, izinto ezifana nokusingqongileyo, iimfuno ze-bandwidth, kunye nemithombo enokuthi iphazamiseke kufuneka ithathelwe ingqalelo. Ukusebenza okuchanekileyo nokuthembekileyo, kubalulekile ukukhetha uhlobo lwentambo ephothiweyo efanelekileyo kwiimfuno zakho zofakelo.
Isishwankathelo, kukho iintlobo ezininzi zeentambo eziphothiweyo, nganye yenzelwe ukuhlangabezana neemfuno ezithile kunye nezicelo. Nokuba yi-UTP, i-STP okanye yintambo ejijekileyo yangaphandle, ukuqonda iindidi ezahlukeneyo kubalulekile ekukhetheni intambo efanelekileyo kuthungelwano oluthile okanye iprojekthi yonxibelelwano. Ngokuqwalasela iimpawu ezizodwa zodidi ngalunye olujijekileyo lwentambo, abasebenzisi banokuqinisekisa ukuba ngokuchanekileyo, ukuhanjiswa kwedatha ngokufanelekileyo kuthungelwano lwabo.
