Uyintoni umahluko phakathi kweCAT5E kunye neCAT6 kwizakhiwo ezikrelekrele

 

 

Uyintoni umahluko phakathi kwe-CAT5E, CAT6kunye neCAT6A ekusebenzeni kwenkqubo kunye nokusetyenziswa kwenethiwekhi?

 

1. I-CAT5E i-bandwidth ebonakalayo ye-bandwidth: i-100MHz, i-CAT6 ye-wiring bandwidth ebonakalayo: 250MHz;

 

Inkcazo: Ubungakanani bebhendi ebonakalayo ebonakalayo, inyusa izinga lokuhambisa elixhaswayo.

 

2. Iintambo ze-CAT5E zihlala zisebenzisa igeji yocingo engama-24AWG (malunga nobubanzi besiseko sobhedu: 0.51mm), kunye neentambo ze-CAT6 zihlala zisebenzisa i-23AWG yegeji yocingo (ubukhulu besiseko sobhedu malunga ne-0.57mm);

 

Inkcazo: Ukutyeba kububanzi besiseko sobhedu, kokukhona ukusebenza kokuqhuba, kunye nokuncitshiswa kwempawu emgceni. Kwizicelo ze-PoE, i-23AWG inenzuzo engaphezulu kwe-24AWG kudluliso lwamandla.

 

3. Elona zinga liphezulu lokuhambisa idatha lixhaswe yithiyori ye-CAT5E ye-wiring yi-1200Mbps, kwaye elona zinga liphezulu lokuhambisa idatha lixhaswe yithiyori ye-CAT6 ye-wiring yi-2400Mbps;

 

Inkcazo: Ukunyuka kwenqanaba lokudluliswa kwedatha, kokukhona ubukhulu bebhendi ebonakalayo.

 

4. Umgangatho wesicelo se-10GBASE-T 10G Ethernet ongasetyenziswanga ziintambo ze-CAT5E, kunye nomgangatho wesicelo se-10GBASE-T Ethernet onokuxhaswa yi-CAT6, kodwa umgama wokuhambisa ulinganiselwe kwaye awunakugqitha kwiimitha ezingama-37.

 

Inkcazo: Udidi lwe-6 inkqubo yeekhabhathi ayinakuhlangabezana neemfuno zesicelo se-10 yeGigabit Ethernet kwimigama emifutshane, ngelixa iinkqubo zeCandelo 5 zingenakuyixhasa.

 

5. Iintambo ze-CAT6 zihlala zisebenzisa isakhelo somnqamlezo ukunciphisa crosstalk phakathi kwezibini. Its (NEXT) kufutshane nokuphela kwesalathiso sokusebenza kwe-crosstalk yi-5-10dB ephezulu kunaleyo ye-CAT5E ngaphandle kwesakhelo (1-100MHz);

 

Inkcazo: Ukunciphisa i-crosstalk phakathi kwezibini yeyona nto ibalulekileyo esisiseko sokuhambisa okuzinzileyo kunye nesantya esiphezulu sokuhambisa ulwazi lwedatha kwinkqubo yeentambo

 

Ngokuthelekisa ngokuthe gabalala umahluko phakathi kwala manqanaba mabini akhankanyiweyo weenkqubo zeentambo, inkqubo yeentambo zeCandelo 6 ayisiyiyo nje iphezulu kakhulu kunenkqubo yokufaka iikhabhathi ngokweCandelo 5 ngokokusebenza komzimba kunye nombane, kodwa ikwaphezulu kakhulu kunodidi lwenkqubo 5 yeentambo Imigaqo yokuhanjiswa kwesantya esiphezulu kunye nokuzinzileyo kwedatha. Kwangelo xesha, njengoko udidi lwe-6 lweemarike zentambo luqhubeka nokukhula, ukukhuthazwa okukhulu kweemveliso zodidi 6 kuqhuba ukuveliswa kweemveliso ezinkulu zodidi lwe-6, kusenza ixabiso lodidi lweemveliso zentambo ezingaphezulu kakhulu kunexabiso kwamahlelo angaphezu kwama-5.

 

Uyintoni umahluko phakathi kwe-CAT5E, CAT6kunye neCAT6A ekusebenzeni kwenkqubo kunye nokusetyenziswa kwenethiwekhi?

 

Okulandelayo, nantsi inkcazo emfutshane ngomahluko ekusebenzeni kwemveliso phakathi kweenkqubo zeCAT6 kunye neCAT6A:

 

1. I-CAT6 ye-bandwidth ebonakalayo ye-bandwidth: 250MHz, i-CAT6A ye-bandwidth ebonakalayo yomzimba: 500MHz;

 

Inkcazo: Ubungakanani bebhendi ebonakalayo ebonakalayo, inyusa izinga lokuhambisa elixhaswayo.

 

2. CAT6 intambo loop ukumelana (ngo 20â „ƒ) 155 ohm / km, ixabiso NVP: 69%;

 

CAT6A intambo yokuxhathisa ngentambo (kwi-20 ° C) 150 ohm / km, ixabiso le-NVP: 76%;

 

Inkcazo: Incinci ukumelana nobhedu lwendalo, kokukhona ukusebenza kokuqhuba, kunye nokuncitshiswa kwempawu emgceni. Ixabiso lentambo yeNVP yipesenti yenqanaba lokuhambisa umbane kumgangatho wobhedu olingana nesantya sokukhanya kwincam. Ukunyuka kwexabiso le-NVP, ngokukhawuleza isantya sokuhambisa umqondiso we-elektroniki phakathi.

 

3. Umgangatho wesicelo se-10GBASE-T 10 seGigabit Ethernet exhaswa yiCAT6, kodwa umgama wokuhambisa ulinganiselwe, awudluli kwiimitha ezingama-37 (kunye nesidingo sokwandisa uvavanyo lwangaphandle lwe-crosstalk ukuphinda uvavanye ukusebenza kweCandelo 6 lenkqubo yeekhabhathi ngokuchasene Ukuphazamiseka kwangaphandle ngombane). I-CAT6A ye-cabling inokuxhasa i-10GBASE-T Ethernet esemgangathweni yesicelo, ehlangabezana nesicelo semigangatho ye-100 yemitha ngaphandle kovavanyo lwangaphandle lwe-crosstalk.

 

Inkcazo: Inkqubo ye-CAT6A ye-cabling inokuhlangabezana ngokupheleleyo neemfuno zesicelo se-10 Gigabit Ethernet kumgama weemitha ezili-100, kwaye zininzi iziphene kuthumelo lwe-10 Gigabit Ethernet yinkqubo ye-CAT6 yeekhabhathi.

 

Intambo ye-CAT6A ihlala isebenzisa indlela ye-aluminium foil yokukhusela kunye ne-aluminium foil yokukhusela iyonke ukuze ifezekise ukusebenza okuhle kakhulu kokukhusela ukuphazamiseka kwangaphandle kwe-electromagnetic kunye ne-crosstalk phakathi kwezibini. I-crosstalk phakathi kweentlobo ezintandathu zeeparitha ezijijekileyo ezingafakwanga zesakhelo somnqamlezo iyi-15-35dB ephezulu kuluhlu lwe (1-250MHz).

 

Inkcazo: Ukunciphisa i-crosstalk phakathi kwezibini kunye nokuphepha ukuphazamiseka kwangaphandle kwe-electromagnetic kwiintambo zezona zinto zibaluleke kakhulu kwisiseko sokuhambisa okuzinzileyo kunye nesantya esiphezulu solwazi lwedatha kwinkqubo yeentambo.

 

Inkqubo yokudibanisa iintambo iphuhliswe ngaphezulu kweminyaka engama-20. Ngokwandiswa kwezicelo zenethiwekhi kwiinkalo ezahlukeneyo, inani lamazibuko lenyuke kakhulu. Kwaye kunye nophuhliso oluqhubekayo lwetekhnoloji yolwazi, abasebenzisi baneemfuno eziphezulu neziphezulu zesantya senethiwekhi. Ukuxhasa ukukhula kwesantya sothungelwano, inkqubo yekhabhathi yenethiwekhi ikwandisiwe ukusuka kwiindidi ezintathu zokuqala zeenkqubo ukuya kwinkxaso yanamhlanje yokuhanjiswa kwe-10 yeGigabit. I-CAT6A (Ikati 6), inokubonelela ngezinga lokuhambisa elithe tyaba leeGigabits ezili-10 kunye ne-10Gbps. Ke okwangoku, ukuhanjiswa kokusebenza kwekhabhathi yobhedu akusasebenzi njengebhotile yesicelo.
