Dab tsi yog Edfa Amplifier

Edfa (Erdbium-doped fiber ntau amplifier), Firstly tsim nyob rau hauv xyoo 1987 rau kev lag luam zoo tshaj plaws hauv xyoo 1987-deptomer fiber ntau li optical amplification nruab nrab los kho cov cim. Nws ua rau lub qhov kub tam sim ntawd rau cov cim nrog ntau nthwv wavelengths, cia li tsis pub dhau ob pawg. Ib qho yog cov lus pom zoo, lossis C-Band, kwv yees li ntawm 1525 nm, thiab lwm yam yog ntev, lossis L-band, kwv yees li ntawm 1570 nm. Meanwhile, nws muaj ob feem ntau siv cov banding bands, 980 nm thiab 1480 nm. Tus 980nM band muaj qhov kev tiv thaiv kev nqus tau ntau dua nyob rau hauv cov ntawv sau tsis muaj suab npe, thaum muaj qhov qis dua rau cov hluav taws xob siab dua.

Cov duab hauv qab no kom ntxaws txog qhov ua piv txwv li cas EDFA amplifier txhim kho cov cim. Thaum lub Edfa Amplifier ua haujlwm, nws muaj lub twj tso kua mis laser nrog 980 nm lossis 1480 nm. Thaum lub twj tso kua mis laser thiab cov cim tawm tswv yim tshaj dhau los ntawm cov kauj vab, lawv yuav yog cov khoom siv fiber ntau. Los ntawm kev sib cuam tshuam nrog doping ions, lub teeb liab kev ua qe tuaj yeem ua tiav tau. Qhov kev siv hluav taws xob no tsis tsuas yog txo qis tus nqi tab sis txhim kho kev ua tau zoo rau kev siv kho qhov muag. Hauv ntej, ursfa amplifier yog qhov tseem ceeb nyob rau hauv keeb kwm ntawm keeb kwm ntawm ib fiber ntau dua nrog ntau cov hluav taws xob muaj peev xwm ua tau ib lub fiber ntau, hloov saib cov hluav taws xob-kho kom zoo.

Beijing Rofea Optoelectronics CO, Ltd nyob hauv Suav teb "silicon Valley" Beijing Institection Production thiab Enterpise Science Cov Neeg Ua Haujlwm Kev tshawb fawb thiab kev tsim kho, tsim khoom, kev muag khoom ntawm Optoelectronic khoom, thiab muab cov kev daws teeb meem tshiab thiab kev tshaj lij, kev pabcuam tus kheej rau kev tshawb nrhiav kev lag luam thiab cov khoom siv ywj siab, nws tau tsim cov kev txhim kho ywj siab, kev thauj mus los, kev kawm, kev kho mob, kev kho mob, kev kho mob thiab lwm yam Kev lag luam.Gre ua qhov zoo nyob rau hauv kev lag luam, xws li kev kho lossis cov kev pabcuam zoo, muaj kev pab zoo, muaj cov ntawv pov thawj muaj patent Daim ntawv pov hwm, muaj zog, cov khoom muag muag hauv tsev thiab cov chaw lag luam dav hlau, nrog nws ruaj khov, zoo dua kev ua tau los ntawm cov neeg siv hauv tsev thiab txawv teb chaws!
