Sida aynu wada ognahay, dareemaha Gigabit Ethernet guud ahaan waxay leeyihiin laba nooc oo dekedo ah: dekedaha RJ45 iyo dekedaha SFP. Labada nooc ee dekeduhu waxay qaadi karaan gudbinta Gigabit Ethernet, markaa waa maxay farqiga u dhexeeya? Deked noocee ah ayaa loo baahan yahay in la isticmaalo si loo xaqiijiyo isku xirka Gigabit Ethernet?

Waa maxay dekedda RJ45 ee ku taal Gigabit Ethernet?
Dekadda RJ45 ee beddelka Gigabit Ethernet waa deked ku dhex dhisan. Noocan dekedda ah waxaa loo isticmaali karaa gelitaanka server-ka ee xarunta xogta, LAN, iyo kor u kaca ee shirarrada desktop-ka ama Gigabit ilaa codsiyada bandwidth desktop. Marka laba Gigabit Ethernet furaha ay ku xiran yihiin, fiilooyinka caadiga ah ee isku xiran ayaa badanaa la isticmaalaa, sida CAT-5, CAT-5, CAT-6, iyo CAT-6 jumpers network.

Waa maxay dekedda SFP ee ku taal Gigabit Ethernet?

Dekadda SFP (interface hot-swappable yar) waxa kale oo loo yaqaan dekedda mini-GBIC, heerka gudbinta waa 1G, oo waxay taageeri kartaa isku xirka copper ama isku xirka indhaha (in Ethernet, heerka dekedda SFP waa 1Gbit/s, in nidaamka fiber channel In, heerka dekedda SFP wuxuu gaari karaa 4Gbit/s). Marka la geliyo moduleka is-dhexgalka korantada ee dekedda SFP, waxaa badanaa lagu xiraa fiilada shabakadda (Cat5/Cat5e/Cat6) ee gudbinta xogta. Marka moduleka dekedda indhaha la geliyo dekedda SFP, waxaad u baahan tahay inaad isticmaasho jumper LC si aad u gaarto gudbinta fogaanta dheer. Intaa waxaa dheer, codsiyada sida xarumaha xogta iyo shabakadaha aagga maxalliga ah (LAN), dekedda SFP ee beddelka waxay sidoo kale leedahay 100/1000Mbps la-qabsiga.

dekedda RJ45 VS SFP dekedda

Marka laga eego dhinaca kor ku xusan, waxqabadka dekedda RJ45 iyo dekedda SFP asal ahaan waa isku mid; laakiin marka la eego dhinaca kharashka, qiimaha xargaha ee dekedda SFP ayaa ka sarreeya. Si kastaba ha ahaatee, dekedda SFP weli waa lagama maarmaan sababtoo ah waxay taageeri kartaa laba nooc oo ah SFP modules dekedda korontada iyo SFP modules dekedda indhaha. Marka la isticmaalayo SFP modules indhaha dekedda indhaha, masaafada gudbinta sidoo kale waa ka dheer yahay in dekedaha RJ45. Codsiyada la taaban karo, waxa ay leedahay dabacsanaan Sare, iyo scalability sidoo kale waa mid aad u sarreeya.
