Ukuvela kwe-Category cabling kanye nekusasa lenethiwekhi yakusasa
Iqale yethulwa ngabakwa-CommScope, njenge-SYSTIMAX® GigaSPEED® X10D, ngo-2004 futhi yamiswa ngo-2009, Isigaba 6A sihlala siyingqalasizinda enconyiwe yokwakha okusha kwesimanje.
Ngo-2004, imboni yabona ukulinganiselwa komkhawulokudonsa wezigaba zekhebula zeSigaba 5 kanye neSigaba sesi-6 kuzokukhinyabeza kakhulu ukukhula nokuthuthukiswa kwenethiwekhi. Inselele enkulu bekuwukusekela amanani edatha aphezulu ebangeni elide, uma kuqhathaniswa neSigaba 6.
Iholwa yi-IEEE 802.3an 10GBASE-T Task Force, ukusesha kwesixazululo esikwazi u-10 GE kwakuvuliwe. Baqale ngokubhekana nezindaba ezibalulekile ezifana nokulahleka kokubuya, i-crosstalk, nomsindo ovela eziteshini zekhebula eziseduze (i-alien crosstalk). Umsebenzi wabo uphumele ekucacisweni kwesiteshi sekhebula esincane se-10GBASE-T kanye nekilasi elisha lokusebenzisa ikhebula, I-Class EA, eyaziwa nangokuthi Isigaba sesi-6 esithi “Augmented”. Ngo-Okthoba 2004 i-Cat 6A yazalwa ngokusemthethweni.
Njengoba izinhlelo zokusebenza ezintsha zidinga ukusebenza okungcono kwekhebula, amanani okutholwa kwe-Cat 6A aye anda kancane kancane. Abashayeli abanjengo-IoT, i-Wi-Fi 6/6E/7, i-PoE enamapheya amane, ukukhanya okuhlakaniphile, ukulawula isakhiwo/ukuzenzakalela, amaselula okwakha ngaphakathi, nokunye, kuzonweba ukutholwa kweSigaba 6A ngekusasa elibonakalayo.
Ngokusekelwe kugrafu, kubukeka sengathi imali ehlakaniphile iseSigabeni 6A.
I-CAT 6A: Amaqiniso anzima
Isivinini senethiwekhi vs span: Ukushesha kangakanani kuncike ekutheni kude kangakanani
Idizayini eningi yenethiwekhi incike ekutheni idatha ikhiqizwa kuphi nokuthi kufanele icutshungulwe futhi igcinwe kuphi. Izinsiza zenethiwekhi ezengeziwe ziya onqenqemeni kuyilapho isivinini sedatha nezimfuno zomthamo zilokhu zikhula ngaphezu kwamandla enethiwekhi ekhona Yesigaba 5 kanye Nesigaba 6.
Ngokucacile, Isigaba 5/6 sisengozini yokonakala kwesiteshi okudalwe ngaphakathi kwendawo yokusebenza. I-Crosstalk, i-impedance mismatch, umsindo wangaphandle, ukulahleka kokubuyisela, nezinye izinkinga kubangela amaphutha amancane anganciphisa konke okuphumayo. Isigaba 6A sokubamba ikhebula siklanyelwe ngokukhethekile ukunqoba lezi zinselele, okwenza amanethiwekhi akwazi ukusekela amashaneli angu-10 GE afika kumamitha angu-100—cishe ubude obuphindwe kathathu kuneSigaba 6.
Hhayi nje noma iyiphi i-Cat 6A. Umndeni wakwa-CommScope wezixazululo zeSigaba 6A uhlinzeka ngekhebula elithuthukisiwe nokusebenza kwesixhumi, ukuze ukwazi ukusekela izidingo zakamuva ze-10 GbE.
| Isigaba | Umkhawulokudonsa | Ibanga le-1G | Ibanga le-10G |
| Ikati 5e | 100 MHz | 100m | --- |
| Ikati 6 | 250 MHz | 100m | 37m |
| Ikati 6A | 500 MHz | 100m | 100m |
| Ikati 7 | 600 MHz | 100m | 100m |
| Ikati 7A | 1000 MHz | 100m | 100m |
| Ikati 8 | 2000 MHz | 100m | 100m |
Ukuhlangabezana namazinga wamandla e-PoE kumadivayisi axhunyiwe
Ukuhlangana kwenethiwekhi ngokugcwele esikhaleni sebhizinisi kuyaqhubeka. Ama-OEMs edivayisi asizakala ngamazinga e-PoE abuyekeziwe anika amandla wonke amakhebula amakhebula amane ukuphinda kabili ukulethwa kwamandla uma kuqhathaniswa nezinhlelo zokusebenza ze-PoE zisebenzisa amapheya amabili nje. Kuzinhlelo zokusebenza ezidinga ngaphezu kwama-watts angu-25.5, okuwukuphela kwesisombululo sekhebula esinconywa ngamazinga ukuthi, ukuqagele, i-Cat 6A.
Amandla avela kumishini ye-LAN ene-PSE yokuphela kwesikhathi (phezulu) kanye ne-mid-span (phansi)
