SFP Transceiver？ Dab tsi yog
SFP optical module yog ib hom interface uas hloov pauv gigabit hluav taws xob teeb liab mus rau lub teeb liab kho qhov muag. Nws yog ib qho qauv me me pluggable gigabit optical transceiver module, tuaj yeem txuas rau SFP cov chaw nres nkoj ntawm cov khoom siv hauv network xws li cov hloov kab, cov hloov pauv, cov hloov pauv, thiab siv los txuas kho qhov muag lossis tooj liab network cable rau cov ntaub ntawv xa, nws feem ntau pom hauv Ethernet keyboards , routers, firewalls, thiab network interface phaib.
SFP chaw nres nkoj yog dab tsi?
Raws li tau hais los saum no, SFP cov chaw nres nkoj feem ntau pom muaj nyob hauv cov khoom siv hauv network xws li hloov chaw, hloov pauv, hloov khoom siv xov xwm, thiab lwm yam. Koj puas paub SFP cov chaw nres nkoj? SFP chaw nres nkoj tsuas yog siv rau cov teeb liab hloov pauv thiab cov ntaub ntawv xa mus. Qhov chaw nres nkoj tau ua raws li IEEE 802.3ab tus qauv (xws li 1000BASE-T) thiab qhov chaw sib kis tau ntev tshaj plaws yog 1000Mbps (Chaw nres nkoj ntawm SFP chaw nres nkoj txhawb 100 / 1000Mbps).
SFP chaw nres nkoj kom zoo dua
SFP chaw nres nkoj yog qhov kub-hloov mus rau I / O interface (rau kev tawm tswv yim / tso zis interface). Nws yog hloov tau thiab tuaj yeem siv ntau yam khoom lag luam, xws li 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-ZX lossis 1000BASE-BX10-D / u. Ntxiv rau, SFP chaw nres nkoj qis qis dua, txhawb rau 101001000mbps.
SFP chaw nres nkoj rau kev hloov mus Gigabit
SFP chaw nres nkoj ntawm gigabit hloov tuaj yeem siv los txuas kev hloov qhov muaj peev xwm ntawm txhua lub network los txuas ntau hom fiber ntau (xws li ib hom thiab ntau hom fiber ntau) thiab cov tshuab dhia network (xws li CAT5E thiab Cat6), txawm li cas los xij, Qhov chaw nres nkoj SFP ntawm qhov hloov chaw gigabit yuav tsum tau muab tso rau hauv SFP optical module ua ntej nws siv tau rau cov ntaub ntawv sib kis siv cov fiber ntau jumper thiab network jumper. Txhua lub lag luam qib hloov tam sim no muaj tsawg kawg ob qhov SFP chaw nres nkoj, uas tuaj yeem siv los tsim lub nplhaib lossis lub hnub qub network cov topologies sib txawv ntawm cov tuam tsev sib txawv, cov plag tsev lossis thaj chaw los ntawm kev sib txuas ntawm cov fiber ntau them rau cable thiab network dhia. Vim li cas SFP Transceiver thiaj li nrov?
Qhov loj ntawm SFP Transceiver yog ib nrab ntawm qhov GBIC module, thiab tus naj npawb ntawm SFP qhov chaw nres nkoj ntawm tib lub vaj huam sib luag yuav yog ob npaug ntawm GBIC module, raws li qhov siab xav tau ntawm cov ntaub ntawv nruab nrab, SFP optical module yuav hloov GBIC optical module yav tom ntej.
Daim ntawv thov ntawm SFP optical module
1. Lub luv luv network cabling
Lub 1000BASE-T SFP optical module txhawb 10/100/1000 kev hloov kho thiab Auto MDIX / MDIX, tuaj yeem siv nrog 5 hom kev ua haujlwm tsis sib xws ntawm lub network, thiab cov kis tau mus txog 100m.
2. Lub nrug ntev cabling
1000BASE-EX thiab 1000BASE-ZX SFP optical modules siv tau nrog tib hom kho qhov muag fiber thiab tsim nyog rau kev sib kis ntev ntawm network. Kev sib kis deb ntawm 1000BASE-EX SFP optical module tuaj yeem ncav cuag 40km, thiab qhov ntawd ntawm 1000base-zfp optical module tuaj yeem ncav cuag 80km.
Nco tseg: thaum siv ib hom fiber ntau (SMF) hla kev ncua deb luv luv, lub ntsej muag kho qhov muag tau muab tso rau hauv qhov txuas kom tsis txhob muaj tus neeg nqa khoom ntau dhau.
Xaus
SFP chaw nres nkoj tuaj yeem txhawb nqa ob qho SFP Transceiver thiab SFP optical module. Tsis muaj teeb meem dab tsi, SFP chaw nres nkoj thiab SFP optical module muaj qhov yooj thiab qhov yooj yim hauv cov ntawv thov siv, uas yog cov tshuaj zoo rau Gigabit Ethernet.
