Waa maxay moduleka SFP?

Module-ka SFP waa qalab is-dhexgal ah oo u beddela calaamadaha korantada ee gigabit-ka calaamadaha indhaha. Waa halbeegga warshadaha oo yar oo la xidhi karo gigabit transceiver module kaas oo lagu xidhi karo SFP ee qalabka shabakada sida furayaasha, router-yada, iyo beddelayaasha warbaahinta. Dekadda waxaa loo isticmaalaa in lagu xidho fiilooyinka shabakadaha naxaasta ah ee gudbinta xogta. Caadi ahaan waxaan ka heli karnaa furayaasha Ethernet, router-ka, dab-damiska iyo kaararka is-dhexgalka shabakada.

Waa maxay dekedda SFP?

Sida kor ku xusan, dekedaha SFP waxaa caadi ahaan laga helaa qalabka shabakadaha sida shisheeyaha, router-ka, beddelayaasha warbaahinta, iwm. Runtii ma taqaanaa dekedaha SFP? Dekadda SFP waxaa inta badan loo isticmaalaa beddelka calaamadaha iyo gudbinta xogta. Dekeddeedu waxay la jaanqaadaysaa heerka IEEE 802.3ab (sida 1000BASE-T), masaafada ugu badan ee gudbinta waxay gaari kartaa 1000 Mbps (dekedda SFP ee furaha waxay taageertaa 100/1000 Mbps).

Faa'iidooyinka dekedda SFP

Dekadda SFP waa mid kuleyl ah oo la isku beddeli karo I / O interface (oo loola jeedo wax gelinta / soo saarista), kaas oo leh dabacsanaan xooggan oo ku habboon noocyo kala duwan oo alaab ah, sida 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-ZX ama 1000BASE -BX10-D/U dekedaha waa la bedeli karaa, iyo dekedda SFP waa dib u socon kara, taageeraya 10/100/1000Mbps.

Dekedda SFP ee Gigabit beddelka

Dekadda SFP ee beddelka Gigabit waxaa loo isticmaali karaa in lagu ballaariyo shaqada beddelka ee shabakadda oo dhan iyadoo la isku xirayo noocyo kala duwan oo fiilooyinka indhaha ah (sida hal-mode iyo fiber-mode fiber) iyo jumpers network (sida Cat5e iyo Cat6), laakiin Dekadda SFP ee beddelka Gigabit Module-ka indhaha ee SFP waa in la geliyo ka hor inta aan la isticmaalin, ka dibna loo isticmaalo boodboodka fiber-ka iyo boodayaasha shabakadda si loo gudbiyo xogta. Maalmahan, dhammaan furayaasha heerka-shirkadeed ee suuqa ka jira waxay leeyihiin ugu yaraan laba dekedood oo SFP ah, kuwaas oo ka dhisi kara giraanta ama shabakada topologies inta u dhaxaysa dhismayaal, sagxyo ama gobollo kala duwan iyada oo loo marayo isku xirka fiilooyinka sida fiilooyinka indhaha iyo jumpers network.
