Vim li cas thiaj siv EDFA fiber ntau amplifiers?
Muaj ntau ntau qhov sib txawv hauv cov txheej txheem kho qhov muag fiber ntau, xws li C-band (1530nm-1560}nm) thiab L-band (1560nm-1600nm). Cov kab sib txawv muaj qhov sib txawv wavelength, thiab kev sib txuas lus yuav raug cuam tshuam. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua kom lub ncua sij hawm ntawm qhov txuas optical fiber ntau. Tsuas yog cov band channel tuaj yeem ua kom muaj kev sib txuas lus ib txwm muaj.
EDFA fiber ntau amplifiers tsuas yog ua tau raws li qhov xav tau no. Nws tuaj yeem siv cov fiber ntau seem los ua qhov nruab nrab kom nthuav dav cov teeb liab kho qhov muag thiab nthuav dav qhov dav dav (1500nm-1600}nm), txaus los nthuav cov ntaub ntawv raws nrog cov ntaub ntawv siab tshaj plaws. Cov yam ntxwv no tuaj yeem ua lub luag haujlwm ntau dua hauv WDM multi-channel optical transmission system, thiab yog li ntawd tau dhau los ua ib feem tseem ceeb ntawm WDM system.
