Ngexesha lokuqhuma kolwazi, phantse wonke umntu ufuna ukufikelela kwi-intanethi, kwaye phantse yonke indawo ixhotyiswe ngenethiwekhi kunye nentambo yenethiwekhi, kodwa awukwazi ukuba nangona intambo yenethiwekhi ibonakala ifana, kukho iindidi ezahlukeneyo.Apha, eli nqaku liza kuthelekisa i-Cat5e (super 5) esetyenziswa ngokubanzi intambo yenethiwekhi, i-Cat6 (6) intambo yenethiwekhi, i-Cat6a (super 6) intambo yenethiwekhi kunye ne-Cat7 (7) intambo yenethiwekhi, ukwenzela ukukunceda ukhethe intambo yenethiwekhi efanelekileyo.
Intambo yenethiwekhi yaziwa ngokuba yi-network jumper kunye ne-twisted pair, idla ngokusetyenziswa kunye ne-RJ 45 crystal head, kuba iphantsi kwaye isetyenziswa ngokubanzi kwi-LAN, kwaye intambo yenethiwekhi yeyona ndlela iqhelekileyo yokuhambisa i-wiring edibeneyo.
I-Cat5e isebenza ngendlela efanayo nentambo yenethiwekhi ye-Cat6, zombini inohlobo olufanayo lweplagi ye-RJ-45, kwaye inokudityaniswa kuyo nayiphi na i-jack Ethernet kwikhompyutheni, i-router, okanye esinye isixhobo esifanayo.Nangona zinezinto ezininzi ezifanayo, zineeyantlukwano ezithile, intambo yenethiwekhi yeCat5e ifakwe kwi-Gigabit Ethernet, umgama wokuhambisa ukuya kwi-100m, kwaye inokuxhasa i-1000Mbps isantya sokuhambisa.Iintambo zenethiwekhi ye-Cat6 zinokubonelela ngesantya sothumelo ukuya kuthi ga kwi-10 Gbps kwi-bandwidth ye-250 MHz.Umgama wokuhanjiswa kwentambo yenethiwekhi yeCat5e kunye nentambo yenethiwekhi yeCat6 yi-100m, kodwa xa usebenzisa isicelo se-10 GBASE-T, umgama wokuhanjiswa kwentambo yenethiwekhi yeCat6 unokufikelela kwi-55 m.Umehluko omkhulu phakathi kweCat5e kunye neCat6 yintsebenzo yokuthutha.Ikhebula le-Cat6 line-separator yangaphakathi enciphisa ukuphazamiseka okanye i-proximal crosstalk (I-NEXT).Kwakhona kuphucula i-distal crosstalk (ELFEXT) kunekhebula le-Cat5e, kwaye inokulahlekelwa kwe-echo ephantsi kunye nokulahlekelwa kokufaka.Ke, intambo yeCat6 inokusebenza okungcono.Intambo yenethiwekhi yeCat6 ixhasa isantya sothumelo ukuya kuthi ga kwi-10G kwaye ine-bandwidth ye-frequency ukuya kwi-250 MHz, ngelixa intambo yenethiwekhi ye-Cat6a inokuxhasa i-bandwidth ye-frequency ukuya kwi-500 MHz, kabini intambo yenethiwekhi ye-Cat6.Intambo yenethiwekhi yeCat7 ixhasa i-bandwidth frequency ukuya kuma-600 MHz, kwaye ikwaxhasa i-10 GBASE-T Ethernet.Ukongeza, intambo yenethiwekhi yeCat7 inciphisa kakhulu ingxolo ye-crosstalk xa kuthelekiswa nentambo yenethiwekhi yeCat6 kunye neCat6a.Intambo ye-Cat5e Network, i-Cat6 cable kunye ne-Cat6a intambo ine-RJ 45 ikhonkco, kodwa i-connector ye-Cat7 cable ikhethekileyo, uhlobo lokudibanisa kwayo yi-GigaGate45 (CG45).Okwangoku, intambo ye-Cat6 kunye nentambo ye-Cat6a yamkelwe yimigangatho ye-TIA / EIA, kodwa intambo ye-Cat7 ayifuni.
Intambo yenethiwekhi yeCat6 kunye nentambo yenethiwekhi yeCat6a ifanelekile ukusetyenziswa ekhaya.Endaweni yoko, ukuba usebenzisa izicelo ezininzi, kuya kufuneka ukhethe ngcono intambo yenethiwekhi yeCat7, kuba ayinakuxhasa kuphela izicelo ezininzi, kodwa inokusebenza ngcono.
Oku ngasentla yinkcazo emfutshane yomahluko phakathi kweentambo zenethiwekhi eziqhelekileyo.Iimveliso zenethiwekhi ye-Shenzhen HDV Phoelectron Technology Co., Ltd. zonke izixhobo eziveliswe malunga neemveliso zenethiwekhi, kubandakanywaI-ONUuthotho /OLTuthotho / uthotho lweemodyuli zokukhanya / uthotho lwe-transceiver njalo njalo.Ukuze udale izixhobo zenethiwekhi ezigqwesileyo, inkampani yethu ixhotyiswe ngophando lobuchwephesha kunye neqela lophuhliso, ukubonelela abathengi ngeenkonzo zenkxaso yobugcisa obuphezulu, bamkelekile ukuba bafune abasebenzi ukuba baqonde iimveliso zethu.
