Yintoni iCable yenethiwekhi yeCAT5E?
Intambo yenethiwekhi ye-CAT5e yintambo ye-twisted-pair esetyenziselwa uthungelwano lwekhompyutha enezinga lothumelo lwe-1000Mbps, edla ngokusetyenziselwa uqhagamshelwano lwenethiwekhi yendawo (LAN) emakhaya, eziofisini, ezikolweni nakwezinye iindawo. Iimpawu ezithile zezi zilandelayo:
1. Izinga eliphezulu lokudluliselwa: Ikhebula le-CAT5e lixhasa izinga lokudlulisela ukuya kwi-1000Mbps, eliphindwe ka-10 ngaphezu kweentambo ze-CAT5, kwaye ingasetyenziselwa izicelo zenethiwekhi ezibamba ubuninzi bedatha.
2. Isakhiwo esine-twisted-pair: Intambo ye-CAT5e yenethiwekhi ithatha i-twisted-pair structure, enokunciphisa ngokufanelekileyo amathuba okuphazamiseka komqondiso. Iqulethe izibini ezine zeengcingo, nganye inombala owahlukileyo wokufakwa lula.
3. Ukufakela ngokulula: Ikhebula le-CAT5e isebenzisa i-RJ45 isixhumi: kulula ukuyifaka, iplagi kunye nokudlala, ifanelekile kwi-cabling yangaphakathi ye-short-distance cabling, kwaye kulula ukuyisebenzisa.
4. I-impedance ezinzileyo: Ikhebula le-CAT5e lenziwe ngocingo olucocekileyo lobhedu kunye noyilo olukhethekileyo lwesakhiwo sangaphakathi, esinokugcina ukuzinza koqhagamshelwano kunye nokuhanjiswa kunye nokuqinisekisa umgangatho ophezulu wonxibelelwano lwenethiwekhi.
5. Ukuhambelana kakuhle: Ikhebula le-CAT5e lihambelana ne-CAT5 kunye neenkcukacha zekhebula zangaphambili, kwaye zinokusetyenziswa njengendlela yokukhetha amanethiwekhi amatsha okanye ukuphuculwa kweenethiwekhi ezikhoyo.
Kufuneka kuqatshelwe ukuba intambo yenethiwekhi ye-CAT5e inezinga eliphezulu lothumelo kwaye inokumelana nokuphazamiseka okukhulu, okukhona umgama omde, uphezulu ukuguga nokukrazuka, kwaye ngokubanzi akufanele kudlule i-100 leemitha. Ukongeza, ekubeni imikhwa emibi yokufakela efana nokungcwaba kunye nokugoba inokuchaphazela ukuhanjiswa kweentambo zenethiwekhi, kuyimfuneko ukulandela imimiselo efanelekileyo xa uyifaka.
Umahluko
Kukho umahluko omkhulu ekusebenzeni phakathi kweCandelo 5 kunye neCandelo 6 leentambo zenethiwekhi. Nangona iintambo zodidi lwe-5 zinokuxhasa i-Gigabit Ethernet, ukusebenza kwazo kunokuqwalaselwa kuphela njengenkxaso. Ngokwahlukileyo, iintambo ze-6 zeCandelo zinokuqinisekisa isantya sokusebenza se-Gigabit Ethernet, ukubonelela abasebenzisi ngolwazi oluzinzile kunye nenethiwekhi egudileyo. Oku kuthetha ukuba kwimeko yomthwalo ophezulu okanye ukuhanjiswa kwedatha enkulu, iintambo zoDidi 6 zinokuhlangabezana ngcono neemfuno kwaye zinciphise ukulibaziseka kwenethiwekhi kunye neziganeko ezibambekayo.
Okwesibini: iimpawu zesakhiwo
Ukongeza kwiiyantlukwano zentsebenzo, iCandelo 5 kunye neCandelo 6 iintambo zenethiwekhi nazo zahlukile kwisakhiwo. Udidi lwe-6 i-twisted-pair cable inepropathi efanelekileyo yokukhusela kunye nokongezwa kwee-crossbones kwisakhiwo sayo. Kwangaxeshanye, amacandelo ayo omqhubi ane-diameter enkulu, i-torque encinci, kunye ne-diameter yangaphandle ebanzi. Olu phuculo loyilo lwenza udidi lwe-VI intambo yenethiwekhi ekuthinteleni ukuphazamiseka phakathi kweentambo zenethiwekhi yokusebenza kakuhle, ukuphucula ngokufanelekileyo umgangatho wokuhanjiswa komqondiso.
Okwesithathu: umgama wothumelo kunye nesantya
Ngokubhekiselele kumgama wothumelo kunye nesantya, kukho umahluko phakathi kwentambo yenethiwekhi ye-ultra-five kunye necandelo lesithandathu lentambo yenethiwekhi. Ngokuqhelekileyo, umgama wothumelo lwentambo yenethiwekhi ye-ultra-five ingaphakathi kweemitha ezili-100, ngelixa umgama wothumelo wecandelo lesithandathu lentambo yomnatha unokufikelela kwi-120-150 yeemitha. Ukongezelela, iintambo zeCandelo le-6 ziye zaphucula ukusebenza kwazo ngokubhekiselele kwi-crosstalk kunye nokulahlekelwa kwembuyekezo, okubangelwa ukunciphisa umqondiso omncinci kunye nesantya esikhawulezayo kwinkqubo yokuhambisa. Oku kubalulekile kwiimeko ezifuna ukuhanjiswa komgama omde okanye usetyenziso lwenethiwekhi yesantya esiphezulu.
