Amplifiers Kho Kom Zoo Tshaj Tau Ua Rau Cov Phiaj Hlau Optic

Amplifiers Optical Ua Ntawv Thov rau hauv Tes Haujlwm Fiber Optic

Raws li peb paub, feem ntau optical amplifier ua kom nrov zoo rau cov neeg siv teeb pom kev los ntawm kev tawm suab sib txawv. Tus kho qhov muag ntxiv tsis muaj dab tsi tab sis lub laser tsis muaj lub tswv yim. Optical nce yog tiav thaum lub amplifier yog pumped optically lossis electrically kom ua tiav cov pejxeem inversion. Kho qhov muag amplification nyob ntawm:

Cov kev siv dav dav ntawm cov qhov muag hluav taws xob yog:

Daim duab qhia qhov yooj yim ntawm kev ua haujlwm ntawm optical amplifier

Lub twj tso kua mis sab nraud zog peb nqus los ntawm cov hluav taws xob hauv qhov nruab nrab nquag. Lub tshuab xaj hluav taws xob hloov mus rau qib siab zog uas ua rau cov pejxeem inversion. Cov duab ntawm cov teeb liab tawm tuaj ua rau muaj siab zoo kawg no electros rau qib qis thourhg ib qho kev tshaj tawm emission peocess, ua cov cim hluav taws xob opticla teeb liab.

Kev Taw Qhia Breif

Qhov nruab nrab nruab nrab hauv cov khoom siv fiber ntau kho qhov muag muaj cov npe me 10 mus rau 30m qhov ntev ntawm cov hluav taws xob fiber ntau uas tau maj mam doped nrog lub ntiaj teb tsis tshua muaj npe xws li Erbium, Ytterbium, Neodymium lossis Praseodymium. Cov khoom siv fiber ntau tuaj yeem ua raws li silica, cov tshuaj fluoride-iav lossis cov iav multicomponent iav.

Kev khiav haujlwm ntawm thaj chaw ntawm cov khoom siv no yog nyob ntawm tus tswv tsev cov khoom siv thiab cov ntsiab lus doping. Cov tshuaj fluorozirconate tsom iav tau doped nrog P lossis N tau siv rau kev ua haujlwm hauv 1300-nm lub qhov rais, txij li cov tshiab no ntawm cov ions tuaj yeem ua kom nrov nrov 1300 nm cov lus taw qhia thaum muab tso rau hauv lub khob iav silica.

Cov khoom siv nrov tshaj plaws rau kev siv cov xov tooj sib txuas ntev ntev yog silica fiber doped nrog Erbium, uas yog lub npe hu ua Erbium-doped fiber amplifier lossis EDFA. Kev ua haujlwm ntawm EDFA los ntawm nws tus kheej ib txwm ua rau thaj tsam 1530 txog 1560 nm.

Hnub no Cov Lus Qhia Tseem Ceeb Cov Khoom: C-band 40 Chares Booster EDFA rau DWDM Kev Ua Haujlwm

DWDM-EDFA-BA-O23 Lub Txhaws Txuas Tshaj Tawm yog ib qho yooj yim siv thiab tus nqi tsim nyog rau DWMD fiber optic link amplification uas ua haujlwm ntawm qhov kis tau ntawm qhov txuas. Nws yog tsim los ua kom loj zog ntawm cov tawm suab mus rau sab nraud kom ncav tau qhov txuas ntxiv. Kev siv ob-theem lub twj tso kua mis laser tsim thiab sab hauv Gain Flattening Lim (GFF) los them nqi rau erbium fiber ntau qhov sib txawv, nws muaj lub zog loj hauv lub zog, lub suab qis, thiab mus txog cov zis hluav taws xob: 23dBm. Software tswj hwm yog tus qauv ntawm RS-232 interface rau cov xwm txheej saib xyuas thiab cov twj tso kua mis hloov kho tam sim no.
