Njengoko sonke sisazi, ukutshintshwa kwe-Gigabit Ethernet ngokubanzi kuneentlobo ezimbini zezibuko: izibuko ze-RJ45 kunye ne-SFP. Zombini iintlobo zamazibuko zinokuthwala ukuhanjiswa kwe-Gigabit Ethernet, ke yintoni umahluko phakathi kwabo? Loluphi uhlobo lwe-port ye-Gigabit Ethernet switch ekufuneka isetyenziswe ukuqonda uqhagamshelo lwe-Gigabit Ethernet?

Yintoni izibuko le-RJ45 kwi-Gigabit Ethernet switch?
I-port ye-RJ45 ye-Gigabit Ethernet yokutshintsha i-port eyakhelwe-ngaphakathi. Olu hlobo lwezibuko lunokusetyenziselwa ukufikelela kwiseva kwiziko ledatha, i-LAN, kunye ne-uplink ye-desktop switches okanye i-Gigabit kwi-desktop bandwidth izicelo. Xa iiswitshi ezimbini ze-Gigabit Ethernet ziqhagamshelwe, iintambo eziqhelekileyo eziphothiweyo zidla ngokusetyenziswa, njengeCAT-5, CAT-5, CAT-6, kunye neCAT-6 network jumpers.

Yintoni i-port ye-SFP kwi-switch ye-Gigabit Ethernet?

I-port ye-SFP (i-interface encinci ye-hot-swappable interface) ikwabizwa ngokuba yi-mini-GBIC port, izinga lokudluliselwa yi-1G, kwaye inokuxhasa ikhonkco lobhedu okanye ikhonkco le-optical (kwi-Ethernet, izinga le-SFP le-port yi-1Gbit / s, kwi-fiber channel system In, izinga le-port ye-SFP linokufikelela kwi-4Gbit / s). Xa ufaka imodyuli ye-interface yombane kwi-port ye-SFP, ngokuqhelekileyo ixhunywe ngentambo yenethiwekhi (Cat5 / Cat5e / Cat6) yokuhanjiswa kwedatha. Xa imodyuli ye-optical port ifakwe kwi-port ye-SFP, kufuneka usebenzise i-LC jumper yokuhambisa ukuze ufezekise ukuhanjiswa komgama omde. Ukongezelela, kwizicelo ezifana namaziko edatha kunye neenethiwekhi zendawo zendawo (LAN), i-port ye-SFP yokutshintsha nayo inomsebenzi oguqukayo we-100/1000Mbps.

RJ45 izibuko VS SFP izibuko

Ukusuka kumbono ongentla, ukusebenza kwe-port ye-RJ45 kunye ne-SFP port ziyafana; kodwa ukusuka kwinqanaba lokujonga iindleko, iindleko ze-wiring ze-port ye-SFP ziphezulu. Nangona kunjalo, i-port ye-SFP isadingeka kuba inokuxhasa iindidi ezimbini zeemodyuli ze-SFP zombane kunye neemodyuli ze-SFP optical port. Xa usebenzisa iimodyuli ze-SFP optical port optical, umgama wothumelo nawo ude kune-RJ45 port. Kwizicelo ezisebenzayo, inokuguquguquka okuPhakamileyo, kwaye ukuqina kwakhona kuphezulu.
