Ungayikhetha njani i-CAT6 okanye i-CAT5E ye-PoE switch?

Indlela yokukhethaCAT6okanyeCAT5E Ukutshintsha kwe PoE?

Ukutshintshwa kwe-POE akunakwahlulwa kwintambo yenethiwekhi kwinkqubo yonikezelo lwamandla, ke kufuneka ikhethwe njani intambo yenethiwekhi?

 

Intambo yenethiwekhi kufuneka iqhagamshelwe kwintambo yenethiwekhi ngokwemigangatho ye-568A okanye ye-568B, iintambo ezi-8 kufuneka zixhunywe, kwaye ubude bube ngaphakathi kwe-100 yeemitha. Kungcono umgangatho wentambo yenethiwekhi, kokukhona uzinzo lonikezelo, ubuncinciCAT5EIntambo, ukuba uhlahlo-lwabiwo mali lwanele, unokukhetha iCAT6 Intambo enebanga elide lokuhambisa kunye nefuthe elingcono.

 

 

 

 

 

CAT5E

 

Ikhebula leCat5e linezibonelelo zokuncitshiswa okuphantsi, i-crosstalk encinci, umyinge ophakamileyo we-crosstalk ratio kunye ne-signal-to-noise ratio, kunye nephutha elincinci lokulibaziseka. Iintambo zodidi lwe-5e zisetyenziselwa ikakhulu iGigabit Ethernet.

 

 

 

 

CAT6

Ukuhamba rhoqo kolu hlobo lwentambo yi-1MHz ~ 250MHz, kunye ne-crosstalk ratio esecaleni yenkqubo yomgca we-6 kwi-2000mhz inomda omkhulu, obonelela kabini umda wendlela ye-Super Category 5. Ukuhanjiswa kokusebenza kweCandelo 6 lokufaka iikhabhathi iphezulu kakhulu kunaleyo yeCandelo lesi-5 yokufaka iikhabhathi, kwaye ilunge kakhulu kwizicelo ezinenqanaba lokuhambisa ngaphezulu kwe-1Gbps.

 

 

 

 

Umahluko obalulekileyo phakathi kwemigca emihlanu kunye emithandathu

 

Uluhlu lwe-6 imigca iphucule intsebenzo kwi-crosstalk kunye nelahleko yokubuya. Kwisizukulwana esitsha sokuphindaphindwa kwesicelo senethiwekhi yesantya esiphezulu, ukusebenza ngokukuko kwelahleko yokubuya kubaluleke kakhulu. Kwangelo xesha, imodeli yekhonkco esisiseko icinyiwe kwiindidi ezintandathu zemigangatho, kwaye inkcazo-ntetho yenkwenkwezi yamkelwe kwimilinganiselo engenamda. Ubude bekhonkco obungapheliyo bomgama weentambo kufuneka ungagqithi kwiimitha ezingama-90, kwaye ubude besitishi mabungagqithi kwiimitha ezili-100.

 

 

 

Ngaba i-POE switch kufuneka ikhethe iintambo zenethiwekhi? Ukutshintsha kwe-POE kufuneka kukhethe iintambo zenethiwekhi.

 

Ukufezekisa isiphumo sokubonelela ngombane nge-PoE, kuyacetyiswa ngokubanzi ukuba kusetyenziswe iintambo zenethiwekhi eziDidi 5, udidi 5 lweentambo zenethiwekhi, kunye noDidi 6 lweentambo zenethiwekhi. Izinto zangaphakathi zentambo yenethiwekhi nazo zibaluleke kakhulu. Sukusebenzisa nayiphi na i-aluminium yocingo, ucingo lwe-aluminium olunxibe ubhedu, ucingo lwesinyithi olubhinqileyo, ucingo lwentsimbi, njl., Kungcono usebenzise ucingo lobhedu olucocekileyo.

 

 

 

Kukho iilogo ngokusisiseko kwiintambo zenethiwekhi. Uphawu lwentambo lweCandelo 5 ngu "CAT5", uphawu lwentambo yeCandelo Super 5 ngu "CAT5E", kunye nelogo yeCandelo 6 ziintambo "CAT6". Kamva ngcono. Ukongeza, abalinganiswa abaprintwe kwisingxobo seplastiki sodidi lokwenyani lwesi-5 bacacile, bathambile, kwaye ngokusisiseko abajiki. Umgangatho wokuprinta wokubhala ngesandla ongekho mgangathweni awukho mgangathweni, ezinye iifonti azicacanga, kwaye ezinye zixinekile.
