Iyini ikhebula lenethiwekhi ye-CAT5E?
Intambo yenethiwekhi ye-CAT5e iyikhebula elisontekile elisetshenziselwa amanethiwekhi ekhompyutha anezinga lokudlulisela elingu-1000Mbps, elivame ukusetshenziselwa ukuxhumana kwenethiwekhi yendawo (LAN) emakhaya, emahhovisi, ezikoleni nakwezinye izindawo. Izici eziqondile zimi kanje:
1. Izinga eliphezulu lokudlulisela: Ikhebula le-CAT5e lisekela izinga lokudlulisela elifika ku-1000Mbps, eliphindwe izikhathi ezingu-10 kunezintambo ze-CAT5, futhi lingasetshenziselwa izinhlelo zokusebenza zenethiwekhi eziphatha amanani amakhulu edatha.
2. Isakhiwo esisontekile: Intambo yenethiwekhi ye-CAT5e yamukela isakhiwo esisontekile, esinganciphisa ngempumelelo amathuba okuphazamiseka kwesignali. Iqukethe amapheya amane ezintambo, ngayinye inombala ohlukile ukuze ifakwe kalula.
3. Kulula ukuyifaka: Ikhebula le-CAT5e lisebenzisa isixhumi se-RJ45: kulula ukuyifaka, ukuxhuma nokudlala, ilungele ikhebula yangaphakathi yasendlini, futhi kulula ukuyisebenzisa.
4. I-impedance ezinzile: Ikhebula le-CAT5e lenziwe ngocingo lwethusi oluhlanzekile olunomklamo okhethekile wesakhiwo sangaphakathi, esingagcina ukuzinza kokuxhumana nokudlulisa nokuqinisekisa izinga eliphezulu lokuxhumana kwenethiwekhi.
5. Ukuhambisana okuhle: Ikhebuli ye-CAT5e ihambisana ne-CAT5 kanye nokucaciswa kwekhebula kwangaphambilini, futhi ingasetshenziswa njengenketho yamanethiwekhi amasha noma njengokuthuthukiswa kwamanethiwekhi akhona.
Kufanele kuqashelwe ukuthi intambo yenethiwekhi ye-CAT5e inezinga eliphezulu lokudlulisela futhi ingamelana nokuphazamiseka okukhulu, uma ibanga elide, ukuguga nokuklebhuka liphakama, futhi ngokuvamile akufanele lidlule amamitha ayi-100. Ngaphezu kwalokho, njengoba imikhuba emibi yokufaka efana nokungcwaba nokugoba ingathinta ukusebenza kokudluliselwa kwezintambo zenethiwekhi, kuyadingeka ukulandela imininingwane efanele lapho uzifaka.
Umehluko
Kunomehluko omkhulu ekusebenzeni phakathi kwezintambo zenethiwekhi zeSigaba 5 kanye Nesigaba 6. Nakuba izintambo zeSigaba 5 zingasekela i-Gigabit Ethernet, ukusebenza kwazo kungabhekwa njengokusekelwa ngokulambisa. Ngokuphambene, izintambo zeSigaba 6 zingaqinisekisa isivinini sokusebenza se-Gigabit Ethernet, zinikeze abasebenzisi ulwazi lwenethiwekhi oluzinzile futhi olubushelelezi. Lokhu kusho ukuthi endabeni yomthwalo omkhulu noma ukudluliswa kwedatha enkulu, izintambo zeSigaba 6 zingahlangabezana kangcono nesidingo futhi zinciphise ukubambezeleka kwenethiwekhi kanye nezimo ezisalela emuva.
Okwesibili: izici zesakhiwo
Ngaphezu komehluko wokusebenza, izintambo zenethiwekhi zeSigaba 5 kanye Nesigaba 6 nazo zihlukile ngesakhiwo. Isigaba sesi-6 sekhebula elisontekile linendawo enhle yokuvikela nokwengezwa kwama-crossbones esakhiweni sawo. Ngesikhathi esifanayo, izingxenye zayo ze-conductor zine-diameter enkulu, i-torque encane kakhulu, kanye nobubanzi obungaphandle obukhulu. Lokhu kuthuthukiswa kokuklama kwenza ikhebula lenethiwekhi yesigaba VI ekuvimbeleni ukuphazamiseka phakathi kwezintambo zenethiwekhi ukusebenza okuhle kakhulu, ukuthuthukisa ngokuphumelelayo ikhwalithi yokudluliselwa kwesignali.
Okwesithathu: ibanga lokudlulisela kanye nesivinini
Mayelana nebanga lokudlulisela kanye nesivinini, kukhona futhi umehluko phakathi kwentambo yenethiwekhi ye-ultra-five nekhebula yenethiwekhi yesigaba sesithupha. Ngokuvamile, ibanga lokudlulisela lekhebula lenethiwekhi ye-ultra-five lingaphakathi kwamamitha ayi-100, kuyilapho ibanga lokudlulisela lekhebula lenethiwekhi yesigaba sesithupha lingafinyelela kumamitha ayi-120-150. Ukwengeza, izintambo zeSigaba 6 zithuthukise ukusebenza kwazo ngokuya nge-crosstalk nokulahlekelwa kokubuyisela, okuholele ekuncipheni kwesignali encane kanye nesivinini esisheshayo enqubweni yokudlulisela. Lokhu kubalulekile kuzimo ezidinga ukudluliswa kwebanga elide noma izinhlelo zokusebenza zenethiwekhi yesivinini esikhulu.
