Kwizicelo zesantya esiphezulu, ukukhethwa kweengcingo kunye nezixhobo zentambo zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kunye nokuthembeka. Imfuno yokuhanjiswa kwedatha ngokukhawuleza kunye nokwanda kwe-bandwidth kufuna uqwalaselo ngononophelo lwezinto ezahlukeneyo xa ukhetha izinto ezifanelekileyo. Eli nqaku ligxininisa imiba ephambili ekufuneka iqwalaselwe xa ukhetha i-high-speed wire kunye ne-cable materials, inika ingqiqo malunga nendlela izinto ezifanelekileyo ezinokuthi ziphucule ngayo ingqibelelo yesignali, ukunciphisa ukulahleka komqondiso, kunye nokuqinisekisa ukuhanjiswa kwedatha ngokufanelekileyo.
Umqondiso weMfezeko kunye nokuthotywa
Ukugcina imfezeko yomqondiso kubalulekile kwizicelo ezinesantya esiphezulu. Iingcingo ezikhethiweyo kunye nezixhobo zekhebula kufuneka zibonise ukuthotywa kwesignali ephantsi, ukunciphisa ukulahlekelwa kwamandla omqondiso ngexesha lokuhambisa. Izinto eziphathekayo ezine-dielectric ephantsi kunye ne-tangent yokulahlekelwa, njenge-polyethylene ephezulu (HDPE) okanye i-polytetrafluoroethylene (PTFE), inceda ukugcina umgangatho wesignali, ukunciphisa ukuphazamiseka, nokuqinisekisa ukuhanjiswa kwedatha echanekileyo kumgama omde.
Ulawulo lwe-Impedans
Ulawulo oluchanekileyo lwe-impedance lubalulekile kwiinkqubo zonxibelelwano olukhawulezayo. I-wire kunye ne-cable material kufuneka ibe neepropati zombane ezihambelanayo ukuze kugcinwe i-impedance yeempawu ezifanayo. Oku kuqinisekisa ukusasazwa komqondiso ofanelekileyo, kunciphisa ukubonakaliswa komqondiso, kunye nokunciphisa umngcipheko weempazamo zedatha okanye ukuthotywa komqondiso. Ukukhetha izinto ezinokunyamezela okuqinileyo kunye neempawu zombane ezizinzile, ezifana ne-foamed polyolefin okanye i-ethylene propylene (FEP), inceda ukufezekisa ulawulo oluchanekileyo lwe-impedance.
Ukunciphisa i-Crosstalk kunye ne-EMI
Intambo enesantya esiphezulu kunye nentambo zichaphazeleka kwi-crosstalk kunye nokuphazamiseka kwe-electromagnetic (EMI). Ukukhethwa kwezinto ezifanelekileyo kunokunceda ukunciphisa le miba. Izinto zokukhusela, ezifana ne-aluminium foil okanye i-braided copper shields, zibonelela ngokhuseleko olusebenzayo kwi-EMI yangaphandle. Ukongeza, izixhobo ezine-crosstalk ephantsi, ezinje ngolungelelwaniso lwezibini ezijijekileyo okanye imathiriyeli enejiyometri yokugquma ephuculweyo, inceda ukunciphisa ukudityaniswa komqondiso okungafunekiyo kunye nokuphucula imfezeko yophawu ngokubanzi.
Ukuqwalaselwa kokusingqongileyo
Iimeko zokusebenza kunye nezinto zokusingqongileyo kufuneka zithathelwe ingqalelo xa ukhetha ucingo olukhawulezayo kunye nezixhobo zentambo. Ukwahluka kwamaqondo obushushu, ukufuma, iikhemikhali, kunye nokuvezwa kwe-UV kunokuchaphazela ukusebenza kwezinto kunye nobomi obude. Izinto eziphathekayo ezinozinzo oluhle kakhulu lwe-thermal, ukumelana nomswakama, ukuchasana kweekhemikhali, kunye nokuxhatshazwa kwe-UV, njenge-polyethylene edibeneyo (i-XLPE) okanye i-polyvinyl chloride (PVC), zihlala zikhethwa ukuqinisekisa ukusebenza okuthembekileyo phantsi kweemeko ezahlukeneyo zokusingqongileyo.
Ukukhetha i-high-speed high-speeding wire kunye ne-cable materials ibalulekile ekufezekiseni ukusebenza kakuhle, imfezeko yomqondiso, kunye nokuthembeka. Uqwalaselo olunjengokuthomalalisa umqondiso, ulawulo lwe-impedance, crosstalk kunye nokunciphisa i-EMI, kunye nezinto zokusingqongileyo zingundoqo xa usenza ukhetho lwezinto eziphathekayo. Ngokuphonononga ngononophelo le miba kunye nokukhetha izinto ezinombane ezifanelekileyo, oomatshini, kunye neempawu zokusingqongileyo, abavelisi banokuhlangabezana neemfuno zezicelo zesantya esiphezulu kwaye baqinisekise ukuhanjiswa kwedatha okusebenzayo kunye nokuthembeka.
