Lub hom phiaj ntawm kev siv erbium-doped fiber ntau amplifier
Muaj ntau ntau qhov sib txawv hauv cov txheej txheem ntawm kev sib kis ntawm fiber ntau, xws li C-band thiab L-band. Cov kab sib txawv muaj qhov sib txawv wavelengths, thiab kev sib txuas lus yuav cuam tshuam. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj qhov sib txawv ntawm cov kab sib txuas ntawm qhov sib txuas ntawm fiber ntau los xyuas kom meej cov kev sib txuas lus ib txwm muaj. .
Optical fiber amplifiers muaj qhov yuav tsum tau ua. Lawv tuaj yeem siv cov fiber ntau residual los ua qhov nruab nrab kom nthuav dav cov teeb liab kho qhov muag thiab nthuav dav ntau lub wavelength, uas txaus los nthuav cov ntaub ntawv sib txuas lus nrog cov ntaub ntawv siab tshaj plaws. Cov yeeb yam no ua lub luag haujlwm zoo hauv WDM multi-channel optical kis tau tus mob thiab yog ib feem tseem ceeb ntawm WDM.
Qhov zoo ntawm EDFA fiber ntau amplifier
Ib qho ntawm qhov zoo yog tias qhov optical fiber amplifier tuaj yeem ua qhov kev nthuav dav ntawm optical yam tsis tau mus los ntawm cov txheej txheem kho qhov muag-hluav taws xob-kho qhov muag teeb liab. Kuj tseem muaj qhov nce siab. Qhov nce parameter tseem ceeb dua rau fiber ntau amplifiers. Lub amplifier zoo muaj qhov nce ntawm 33dB, thiab qhov nce ntawm fiber ntau amplifier yog 30-40dB. Muaj qhov nce siab dua.
Lub suab ntsuas me me. Optical fiber amplifier emits lub suab nrov, yog li nws cov suab nrov Performance index tsawg dua li ib txwm, feem ntau 4 ~ 7dB.
Ntau zaus bandwidth. Optical fiber amplifier nyob ntawm lub wavelength ntawm 1550nm nrog ib tug bandwidth ntawm 20-40nm, uas muaj peev xwm nqa tawm multi-channel kis tau tus mob thiab ua rau kom muaj peev xwm kis tau tus mob.
Kev poob qis. Kev ua haujlwm nthwv dej ntawm lub tshuab hluav taws xob kho qhov muag yog nyob rau hauv qhov zoo tshaj plaws nthwv dej ntawm kev sib txuas lus fiber ntau (1500`1600nm), uas yog nyob rau thaj tsam poob qis. Lawm, qhov poob ntawm optical fiber amplifier yog qhov tsawg thiab qhov kev sib kis tau ntev heev.
EDFA fiber ntau amplifier daim ntawv thov scenarios
1. Optical fiber thaiv qhov system.
2. FTTX, FTTH.
3. DWDM optical kev sib txuas lus network.
4. Video optical kis tau tus mob thiab CATV.
5. Analog& digital CATV optical teeb liab kis tau tus mob ntev.
Cov ntsiab lus
Fast (FS) Erbium-doped fiber ntau ua tau raws li RS-232 thiab SNMP raws tu qauv, thiab siv RJ45 rau kev saib xyuas thiab tswj cov chaw taws teeb. Nruab nrog dual tsis tshua muaj kev ua tau zoo 980nm& 1480 lub twj tso kua mis lasers (tso suab nrov twj tso kua mis lasers uas yog cov npe thoob ntiaj teb sab saum toj) thiab kev ua haujlwm siab erbium-doped fiber ntau, uas muaj qhov zoo ntawm qhov tsis sib xws, tsis tshua muaj suab nrov thiab siab. kev ntseeg tau. Cov fiber ntau txuas ntawm erbium-doped fiber ntau yog nruab nrog Muaj lub kaum sab xis kom tsis txhob qhov muag puas thaum siv. Nruab nrog cov cua kub dissipation thiab cua tshuab hauv, nws tuaj yeem ua kom lub neej ntev dua.
