Dab tsi yog aDWDMadjustable kho qhov muag module?
DWDM tunable optical module yog qhov tshwj xeeb kho qhov muag module, uas tuaj yeem xaiv cov channel lossis "xim" ntawm laser emission. Hauv cov ntsiab lus yooj yim, DWDM feem ntau siv cov khoom siv kho qhov muag nrog cov wavelengths ruaj khov, tab sis cov kho qhov muag kho qhov muag muaj cov khoom siv kho qhov muag uas tuaj yeem siv tau txhua lub sijhawm, muaj peev xwm kho qhov wavelength ntawm optical modules kom tau raws li cov kev thov sib txawv. Nws yuav tsum raug sau tseg tias qhov kev hloov pauv wavelength ntawm DWDM tunable optical module tsuas yog siv hauv DWDM system.
Hom ntawmDWDM Adjustable Optical Modules
Hauv kev ua lag luam niaj hnub no, feem ntau yog ob hom DWDM adjustable optical modules.
(1) Kho tau XFP optical module
Lub tunable XFP kho qhov muag module muaj kev sib xyaw ua ke ntawm C-band tunable transmitter thiab cov neeg txais kev ua haujlwm siab, lub wavelength tuaj yeem raug teeb tsa raws li lub neej ntawd hauv 50GH DWDM ITU daim phiaj, thiab qhov siab tshaj plaws ntawm qhov kev kho qhov muag no tuaj yeem ncav cuag 80km ntawm ib hom. fiber ntau.
(2) Adjustable SFP ntxiv rau optical module
Adjustable SFP ntxiv rau optical modules yog cov khoom siv kho qhov muag uas tuaj yeem muab kev sib txuas ceev ceev los ntawm 9.95Gbps txog 11.3Gbps, thiab cov khoom siv kho qhov muag txhawb nqa SFP ntxiv rau cov lus qhia ntxiv.
Nyob rau sab kis, cov ntaub ntawv serial tau dhau los ntawm lub tshuab hluav taws xob txuas mus rau tus tsav tsheb modulator. Modulator tus neeg tsav tsheb modulates C-band txias tunable transmitter rau cov ntaub ntawv xa mus txog li 80km dhau ib hom fiber ntau ntawm kev lag luam tus qauv LC connector, ntawm qhov tau txais, 10G optical cov ntaub ntawv kwj tau zoo los ntawm APD mus rau lub tshuab hluav taws xob txuas ntawm transimpedance amplifier.
Qhov zoo ntawm DWDM Adjustable Optical Modules
Kho qhov muag kho qhov muag modules tau tsim sai heev nyob rau hauv xyoo tas los no, thiab lawv tau ua nrov nyob rau hauv DWDM kis tau tus mob systems vim hais tias ntawm lawv multi-faceted muaj peev xwm, tshwj xeeb tshaj yog thaum ua ke nrog reconfigurable optical add-poob multiplexers (ROADMs). Lub dimming module dhau los ua ib qho kev sib kis muaj zog. Cias muab, DWDM adjustable optical modules muaj cov nram qab no zoo.
(1) Kev hloov kho dav dav. Piv nrog rau cov khoom siv kho qhov muag kho qhov muag, DWDM dimmable optical modules tuaj yeem txuag tau ntau lub sijhawm thiab nyiaj txiag.
(2) Los ntawm kev txo cov kab dav, nws tsim nyog rau 100G tshuab. Lub peev xwm los kho lub wavelength muab kev yooj yim dua rau cov kev xav tau sib txawv.
(3) Tunable lasers hloov wavelengths nyob rau hauv ob peb nanoseconds. Tunable lasers yog ib feem tseem ceeb ntawm tunable optical modules, ib tug high-speed thiab high-kev ua tau zoo kho qhov muag ntaus ntawv uas enables lub xav wavelength yuav tsum reprogrammed nyob rau hauv vib nas this.
DWDM tunable optical modules tuaj yeem ua haujlwm ntawm ntau lub wavelengths thiab kho lub wavelength raws li kev xav tau ntawm cov neeg siv, ua rau nws nrov hauv DWDM systems.
