Iintlobo zeeCable eziphothiweyo: Funda iSiseko
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.
Ezona ntlobo zixhaphakileyo zeentambo eziphothiweyo zimbini eziphothiweyo ezingakhuselekanga (i-UTP) kunye ne-shielded twisted pair (STP). Iintambo ze-UTP zisetyenziswa ngokubanzi kwi-Ethernet kwaye zezona zilula. Zifanelekile kumgama omfutshane kwaye zihlala zisetyenziswa kwiindawo zeofisi. Iintambo ze-STP, kwelinye icala, zinezikhuselo ezongezelelweyo zokuthintela ukuphazamiseka kwe-electromagnetic, zizenza zifaneleke ngakumbi kwiindawo ezinengxolo ephezulu yombane.
Olunye uhlobo lwe-twisted pair cable yi-twisted pair kunye nekhaka le-foil. Olu hlobo lwekhebula lunesikhuselo esongezelelweyo se-foil sokukhusela okongeziweyo ekuphazamisekeni. Ngokuqhelekileyo isetyenziswa kwimizi-mveliso apho umngcipheko wokuphazamiseka kwe-electromagnetic uphezulu.
Ukongeza, kukho iintambo eziphothiweyo ezinamanani ahlukeneyo okujika ngenyawo, njengeCandelo 5e, iCandelo 6, kunye neCandelo 6a intambo. Ezi ndidi zibonisa ukusebenza kunye ne-bandwidth yamandla ekhebula, kunye neendidi eziphezulu ezixhasa ukuhanjiswa kwedatha ngokukhawuleza.
Xa ukhetha uhlobo lweentambo ezimbini ezijijekileyo, izinto ezifana nemekobume eza kusetyenziswa kuyo, umgama ekufuneka ugutyungelwe, kunye nenqanaba lokuphazamiseka kombane okhoyo kufuneka kuqwalaselwe. Ukongezelela, kubalulekile ukuqinisekisa ukuba iintambo zihlangabezana nemigangatho yoshishino efunekayo ekusebenzeni kunye nokuthembeka.
Ngamafutshane, iintambo ezimbini ezijijekileyo ziyinxalenye ebalulekileyo yothungelwano lwale mihla kunye neenkqubo zonxibelelwano. Ukuqonda iintlobo ezahlukeneyo zeentambo eziphothiweyo kunye nokusetyenziswa kwazo kubalulekile ekuyileni nasekuphunyezweni kothungelwano oluthembekileyo nolusebenzayo. Ngokukhetha uhlobo lwentambo ephothiweyo olufanelekileyo lwesicelo esithile, amashishini kunye nemibutho inokuqinisekisa unxibelelwano olungenamthungo kunye nokudluliselwa kwedatha.
