Njengoba sonke sazi, ukushintshwa kwe-Gigabit Ethernet ngokuvamile kunezinhlobo ezimbili zamachweba: amachweba we-RJ45 namachweba we-SFP. Zombili izinhlobo zamachweba zingathwala ukudluliselwa kwe-Gigabit Ethernet, ngakho-ke yini umehluko phakathi kwazo? Hlobo luni lwe-port ye-Gigabit Ethernet switch okufanele isetshenziselwe ukubona ukuxhumana kwe-Gigabit Ethernet?

Iyini imbobo ye-RJ45 ekushintsheni kwe-Gigabit Ethernet?
Imbobo ye-RJ45 ye-Gigabit Ethernet switch iyimbobo eyakhelwe ngaphakathi. Lolu hlobo lwembobo lungasetshenziselwa ukufinyelela kweseva esikhungweni sedatha, i-LAN, kanye nokuxhuma phezulu kwamaswishi edeskithophu noma i-Gigabit yezinhlelo zokusebenza zomkhawulokudonsa wedeskithophu. Lapho kuxhunywe amaswishi amabili e-Gigabit Ethernet, izintambo ezisontekile ezisontekile zivame ukusetshenziswa, njenge-CAT-5, CAT-5, CAT-6, kanye nezijubhu zenethiwekhi ze-CAT-6.

Iyini imbobo ye-SFP ekushintsheni kwe-Gigabit Ethernet?

Imbobo ye-SFP (i-interface encane eshintshashintshayo) ibizwa nangokuthi i-mini-GBIC port, izinga lokudlulisela i-1G, futhi ingasekela isixhumanisi sethusi noma isixhumanisi sokukhanya (ku-Ethernet, izinga le-SFP port yi-1Gbit / s, ohlelweni lwesiteshi se-fiber In, izinga lembobo ye-SFP lingafinyelela ku-4Gbit/s). Uma ufaka imojuli yesixhumi esibonakalayo sikagesi embotsheni ye-SFP, ngokuvamile ixhunywa ngentambo yenethiwekhi (Cat5/Cat5e/Cat6) ukuze kudluliswe idatha. Uma imojula ye-optical port ifakwe embobeni ye-SFP, udinga ukusebenzisa i-LC jumper ukuze uyidlulise ukuze uzuze ukudluliswa kwebanga elide. Ngaphezu kwalokho, ezinhlelweni zokusebenza ezifana nezikhungo zedatha namanethiwekhi endawo (LAN), imbobo ye-SFP yokushintsha nayo inomsebenzi oguquguqukayo ongu-100/1000Mbps.

Imbobo ye-RJ45 VS SFP port

Kusukela kulo mbono ongenhla, ukusebenza kwechweba le-RJ45 kanye nechweba le-SFP ngokuyisisekelo kuyafana; kodwa kusukela ekubukeni kwezindleko, izindleko zezintambo ze-port ye-SFP ziphakeme. Noma kunjalo, ichweba le-SFP lisadingeka ngoba lingakwazi ukusekela izinhlobo ezimbili zamamojula we-SFP kagesi we-port kanye namamojula we-SFP optical port. Uma usebenzisa amamojula we-SFP optical port optical, ibanga lokudlulisela nalo lide kunalelo lamachweba we-RJ45. Kuzinhlelo zokusebenza ezingokoqobo, inokuguquguquka Okuphezulu, futhi ukukala nakho kuphezulu uma kuqhathaniswa.
