Ikhebula le-Cat8.1, noma ikhebula leSigaba 8.1 wuhlobo lwekhebula ye-Ethernet eklanyelwe ukusekela ukudluliswa kwedatha okunesivinini esikhulu emabangeni amafushane.Kungukuthuthuka kunezinguqulo zangaphambilini zezintambo ze-Ethernet ezifana ne-Cat5, Cat5e, Cat6, ne-Cat7.
Omunye umehluko oyinhloko kukhebula le-Cat 8 ukuvikela kwayo.Njengengxenye yebhantshi lekhebula, ikhebula elisontekile elivikelekile noma elivikelwe (STP) lisebenzisa ungqimba lwezinto eziqhutshwayo ukuze kuvikelwe amakhondatha angaphakathi ekuphazamisekeni kozibuthe kagesi (EMI), okuholela esivinini sokudluliswa kwedatha namaphutha ambalwa.Ikhebula le-Cat8 liqhubekela phambili, ligoqa ipheya ngalinye elisontekile ku-foil ukuze licishe lisuse i-crosstalk futhi linike amandla isivinini sokudlulisa idatha.Umphumela uba ikhebula legeji elisindayo eliqinile futhi okunzima ukulifaka ezindaweni eziqinile.
Ikhebula le-Cat8.1 linomkhawulokudonsa omkhulu ongu-2GHz ophindwe kane kunomkhawulokudonsa we-Cat6a ojwayelekile kanye nomkhawulokudonsa ophindwe kabili wekhebuli ye-Cat8.Lokhu kukhuphuka komkhawulokudonsa kuyivumela ukuthi idlulise idatha ngesivinini esingafika ku-40Gbps ebangeni elingafika kumamitha angama-30.Isebenzisa amapheya amane ezintambo zethusi ezisontekile ukuze idlulise idatha, futhi ivikelwe ukuze kuncishiswe ukuphazamiseka kwe-crosstalk kanye nozibuthe kagesi.

Ikhebula le-Cat 8 Ethernet lilungele ukushintsha ekushintsheni ukuxhumana ezikhungweni zedatha namagumbi eziphakeli, lapho amanethiwekhi angu-25GBase‑T kanye no-40GBase-T avamile.Ngokuvamile isetshenziswa ezikhungweni zedatha, amagumbi eseva, nakwezinye izindawo zekhompuyutha ezisebenza kahle kakhulu lapho ukudluliswa kwedatha ngesivinini esikhulu kubaluleke kakhulu.Kodwa-ke, ayivamisile ukusetshenziswa ezindaweni zokuhlala noma ezincane zehhovisi ngenxa yezindleko zayo eziphezulu kanye nokuhambisana okulinganiselwe nengqalasizinda yenethiwekhi ekhona.
