SFP Module muaj cov cuab yeej kho qhov muag, ua haujlwm hauv Circuit Court thiab kho qhov muag interface.Cov cuab yeej kho qhov muag muaj xws li kis tau tus mob thiab txais qhov chaw.
Kev xa tawm ib feem yog: cov tswv yim ntawm qee tus lej lej ntawm cov teeb liab hluav taws xob, los ntawm kev tsav tsheb hauv nti ua haujlwm, tsav tsheb semiconductor laser (LD) ntawm lub teeb emitting diode (LED) xa tawm cov lej code tus nqi hloov kho qhov muag teeb liab, lub teeb sab hauv yog muab nrog ib tug tsis siv neeg fais fab mov tswj Circuit Court.Qhov tso zis optical teeb liab fais fab tseem nyob ruaj khov.
Qhov tau txais yog: optical teeb liab input module ntawm ib co code tus nqi yog hloov dua siab tshiab rau hauv ib tug hluav taws xob teeb liab los ntawm lub optical detection diode.Tom qab lub preamplifer, cov zis teeb liab ntawm qhov sib thooj me ntsis yog qib PECL.Thaum lub input optical hwj chim tsawg tshaj li ib tug tej yam nqi, lub tswb ceeb toom yog generated.
Parameters thiab lub ntsiab lus ntawm optical modules
Optical modules muaj ib qho tseem ceeb ntawm kev kho qhov muag tsis pom kev.Txawm li cas los xij, rau GBIC thiab SFP hot-plug SFP Modules, koj yuav tsum tau them sai sai rau peb qhov kev txwv hauv qab no.
Raws li nanometer (nm), muaj peb hom tseem ceeb tam sim no.
850nm (MM, ntau hom, tus nqi qis tab sis luv luv kis tau tus mob, feem ntau tsuas yog 500M).
1310nm (SM, Tib Hom, kev sib kis me me, kev tawg loj, feem ntau siv rau kev sib kis ntev tshaj 40KM, tsis muaj relay tuaj yeem xa ncaj qha mus rau 120KM).
1550nm (SM, Tib Hom, kev sib kis me me, kev tawg loj, feem ntau siv rau kev sib kis ntev tshaj 40KM, tsis muaj replay ncaj qha xa tawm 120KM).
Kis tus nqi
Tus lej ntawm cov khoom (BPS) ntawm cov ntaub ntawv xa mus rau ib ob.
Tam sim no.Muaj plaub feem ntau siv SFP Modules.155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps thiab lwm yam.Tus nqi hloov pauv feem ntau yog rov qab sib xws.Yog li, 155M SFP Module tseem hu ua FE (100Mbit / s) SFP Module, thiab 1.25G SFP Module tseem hu ua GE (Gigabit) optical module.
Qhov no yog qhov feem ntau siv SFP hauv cov khoom siv kho qhov muag.Tsis tas li ntawd, nws cov nqi sib kis hauv fiber ntau optic cia systems (SAN) yog 2Gbps, 4Gbps, thiab 8Gbps.
Kev sib kis nrug
Optical teeb liab tsis tas yuav tsum tau xa mus rau qhov kev ncua deb uas lawv tuaj yeem xa ncaj qha.Hauv kilometers (tseem hu ua kilometers, KM).Cov lus qhia tshwj xeeb ntawm SFP Modules yog raws li hauv qab no: Ntau hom 550M, Ib Hom 15KM, 40KM, 80KM, thiab 120KM, thiab lwm yam.
