SFP optical module yog dab tsi?
SFP optical module yog ib vam-kis - hluav taws xob cov lus taw qhia rau lub teeb liab kho qhov muag interface ntaus, yog kev lag luam tus qauv ntawm me pluggable gigabit optical transceiver module, kev sib xyaw ua ke nyob hauv cov chaw hloov, routers thiab lwm yam khoom siv hauv network, media converter SFP chaw nres nkoj, siv los txuas rau lub teeb lossis tooj liab txuas rau cov ntaub ntawv xa mus rau hauv lub network, peb muaj peev xwm feem ntau hauv Ethernet hloov, routers, foob pob hluav taws, thiab pom nws hauv network interface daim npav.
SFP chaw nres nkoj yog dab tsi?
Raws li tau hais los saum no, SFP cov chaw nres nkoj yog tshwm sim ntawm cov keyboards, routers, media converters thiab lwm yam khoom siv hauv network. Koj puas paub SFP ports tiag? SFP chaw nres nkoj tsuas yog siv rau cov teeb liab hloov pauv thiab cov ntaub ntawv xa mus. Qhov chaw nres nkoj ua raws li IEEE 802.3ab tus qauv (xws li 1000base-t), thiab qhov chaw sib kis tau ntev tshaj plaws yog txog 1000Mbps (tus tes hloov qhov chaw nres nkoj SFP txhawb nqa 100 / 1000mbps).
SFP chaw nres nkoj zoo
SFP chaw nres nkoj yog qhov kub-pluggable I / O interface (hais txog qhov tswv yim / tso zis interface), uas muaj cov khoom muaj zog thiab tsim nyog rau ntau yam khoom, xws li 1000base-sx, 1000base-lx / LH, 1000base-zx lossis 1000base-bx10-d / U cov chaw nres nkoj rau kev sib pauv. Ntxiv rau, SFP qhov chaw nres nkoj tuaj yeem rov qab rov qab, txhawb 10/100 / 1000mbps.
SFP chaw nres nkoj rau kev hloov mus gigabit
Gigabit keyboards SFP chaw nres nkoj tuaj yeem txuas nrog ntau hom kho qhov muag los ntawm kev siv ib hom thiab multimode fiber (piv txwv) thiab network jumper (cat5e thiab cat6, piv txwv) siv los nthuav cov 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. Txhua lub lag luam-chav hloov ntawm lub lag luam niaj hnub no muaj tsawg kawg ob qhov SFP chaw nres nkoj uas tuaj yeem siv los ua lub nplhaib lossis lub hnub qub network cov topologies ntawm cov vaj tse sib txawv, cov plag tsev, lossis thaj chaw los ntawm cov kab hluav taws xob thiab cov kab sib txuas cable xws li lub plhaw network.
