Nkuko twese tubizi, Gigabit Ethernet yahinduwe muri rusange ifite ubwoko bubiri bwibyambu: ibyambu bya RJ45 nibyambu bya SFP. Ubwoko bwombi bwicyambu bushobora gutwara Gigabit Ethernet yoherejwe, none itandukaniro irihe hagati yabo? Ni ubuhe bwoko bw'icyambu Gigabit Ethernet ihindura igomba gukoreshwa kugirango umenye Gigabit Ethernet?

Niki cyambu cya RJ45 kuri switch ya Gigabit Ethernet?
Icyambu cya RJ45 cya Gigabit Ethernet switch ni icyambu cyubatswe. Ubu bwoko bwicyambu burashobora gukoreshwa mugukoresha seriveri muri data center, LAN, hamwe no kuzamura desktop ya desktop cyangwa Gigabit kuri desktop yumurongo wa porogaramu. Iyo imiyoboro ibiri ya Gigabit ya Ethernet ihujwe, insinga zisanzwe zigoretse zikoreshwa, nka CAT-5, CAT-5, CAT-6, na CAT-6 zisimbuka.

Niki cyambu cya SFP kuri switch ya Gigabit Ethernet?

Icyambu cya SFP (interineti ishyushye-swappable interface) nayo yitwa icyambu cya mini-GBIC, igipimo cyo kohereza ni 1G, kandi irashobora gushyigikira umuyoboro wumuringa cyangwa guhuza optique (muri Ethernet, igipimo cyicyambu cya SFP ni 1Gbit / s, muri sisitemu ya fibre ya fibre Muri, igipimo cyicyambu cya SFP gishobora kugera kuri 4Gbit / s). Iyo winjije amashanyarazi ya module mumashanyarazi ya SFP, mubisanzwe iba ihujwe numuyoboro wa neti (Cat5 / Cat5e / Cat6) kugirango wohereze amakuru. Iyo moderi ya optique yinjijwe mu cyambu cya SFP, ugomba gukoresha LC gusimbuka kugirango wohereze kugirango ugere kure. Mubyongeyeho, mubisabwa nkibigo byamakuru hamwe numuyoboro waho (LAN), icyambu cya SFP nacyo gifite imikorere ya 100 / 1000Mbps yo guhuza n'imikorere.

Icyambu cya RJ45 icyambu cya VS SFP

Duhereye ku ngingo yavuzwe haruguru, imikorere yicyambu cya RJ45 nicyambu cya SFP ni kimwe; ariko duhereye kubiciro, ikiguzi cyo gukoresha icyambu cya SFP kiri hejuru. Nubwo bimeze bityo, icyambu cya SFP kiracyakenewe kuko gishobora gushyigikira ubwoko bubiri bwamashanyarazi ya moderi ya SFP hamwe na moderi ya optique ya SFP. Iyo ukoresheje port ya optique ya optique ya moderi, intera yoherejwe nayo ni ndende kuruta icyambu cya RJ45. Mubikorwa bifatika, bifite ihinduka ryinshi, kandi ubunini nabwo buri hejuru.
