SFP optical module yog dab tsi?
SFP optical module yog ib vam-kis - hluav taws xob cov lus taw qhia rau lub teeb liab lub ntsej muag interface, yog cov qauv kev lag luam ntawm me pluggable gigabit optical transceiver module, sib xyaw ua ke nyob hauv cov chaw hloov, routers thiab lwm yam khoom siv hauv network, media converter SFP cov chaw nres nkoj, siv los txuas rau lub teeb lossis tooj liab txuas rau cov ntaub ntawv xa mus rau hauv lub network, feem ntau peb tuaj yeem hauv Ethernet hloov, routers, foob pob hluav taws, thiab pom nws hauv network interface daim npav.
SFP chaw nres nkoj yog dab tsi?
SFP chaw nres nkoj feem ntau yog siv rau cov cim kev hloov pauv thiab cov ntaub ntawv xa mus, thiab nws qhov chaw nres nkoj ua raws li IEEE 802.3AB tus qauv (xws li 1000base-T), nrog qhov siab tshaj plaws kis tau mus txog 1000Mbps (hloov' s SFP chaw nres nkoj txhawb 100 / 1000Mbps )).
SFP chaw nres nkoj zoo
SFP chaw nres nkoj yog qhov kub ntsaws I / O interface (hais txog qhov tswv yim / tso tawm interface), nrog kev hloov pauv yooj yim, haum rau ntau yam khoom, xws li 1000 puag-SX, 1000base-Lx / LH, 1000base-Zx lossis 1000base- BX10-d / U chaw nres nkoj sib pauv, ntxiv rau, SFP chaw nres nkoj tuaj yeem sib pauv tau qis, txhawb nqa 10/100 / 1000Mbps.
SFP chaw nres nkoj ntawm gigabit hloov
Gigabit keyboards SFP chaw nres nkoj tuaj yeem txuas rau ntau hom fiber ntau los ntawm kev siv ib hom thiab multimode fiber (piv txwv) thiab network jumper (Cat5e thiab Cat6, piv txwv) tau siv los nthuav kev sib pauv ntawm tag nrho cov network muaj nuj nqi, tab sis gigabit hloov SFP chaw nres nkoj ua ntej siv yuav tsum xub nkag rau SFP optical module, thiab tom qab ntawd siv cov fiber ntau jumper hlau jumper hlau thiab network rau cov ntaub ntawv xa tawm. Nyob rau tam sim no, tag nrho cov kev lag luam hloov chaw hauv khw muaj tsawg kawg yog ob lub SFP chaw nres nkoj, uas tuaj yeem tsim lub nplhaib lossis lub hnub qub network cov topology ntawm cov tuam tsev sib txawv, cov plag tsev lossis thaj chaw los ntawm kev sib txuas ntawm cov hlua hluav taws xob cable thiab network jumpers.
Vim li cas SFP optical modules nrov?
Qhov ntim ntawm SFP optical module yog txo los ntawm ib nrab piv nrog ntawm GBIC optical module. Tus naj npawb ntawm SFP cov chaw nres nkoj ntawm tib lub vaj huam sib luag yuav yog ob npaug ntawm GBIC optical module. Zoo sib xws, SFP qhov kho qhov muag module muaj ntsaws thiab ua si mini fiber ntau qhov, uas ua tau raws li qhov siab xav tau ntawm cov ntaub ntawv chaw.
SFP optical module muaj plaub qhov zoo hauv qab no:
1. Txhawb nqa kub ntsaws, tuaj yeem txo lub installation teeb tsa kev tswj hwm lub sijhawm;
2. Ports yog hloov tau;
3. Rugged tsim txhim kho kev ntseeg tau;
4. Txhawb digital digital optical xyuas (DOM) muaj nuj nqi.
SFP optical module thov
1. Lub luv nrug network cabling
1000Base-T SFP optical module txhawb 10/100/1000 kev hloov kho thiab Auto MDI / MDIX, uas tuaj yeem siv nrog 5 chav kawm ntawm qhov tsis muaj kev tiv thaiv network dhia. Qhov kis tau tus mob ntev txog li 100m.
1000Base-SX SFP optical module tau sib xws nrog IEEE 802.3Z 1000Base-SX tus qauv thiab tuaj yeem siv rau hauv 50m / 62.5 m multimode fiber txuas nrog ntau kis tau mus txog 550m.
2. Lub nrug ntev cabling
1000base-EX thiab 1000base-ZX SFP optical modules tuaj yeem siv ua ke nrog tib hom kev kho qhov muag thiab tsim nyog rau kev sib kis ntev ntawm network, ntawm qhov kis tau mus deb ntawm 1000base-EX SFP optical module tuaj yeem ncav cuag 40km thiab uas ntawm 1000base -ZX SFP optical module tuaj yeem ncav cuag 80km.
Nco tseg: Thaum ib hom fiber ntau (SMF) siv rau kev ncua kev deb, ib tus ntsia hlau hluav taws xob tau muab tso rau hauv qhov txuas kom tsis txhob muaj ntau dhau ntawm qhov txais.
Xaus
SFP chaw nres nkoj tuaj yeem txhawb SFP chaw nres nkoj module thiab SFP chaw nres nkoj module. SFP chaw nres nkoj thiab SFP chaw nres nkoj module muaj qhov yooj thiab qhov yooj yim hauv cov ntawv thov siv, thiab yog cov phiaj xwm zoo rau gigabit Ethernet.
