Muaj ntau lub xov tooj sib txawv hauv cov txheej txheem sib kis ntawm cov khoom siv fiber ntau, xws li C-band (1530nm-1560nm) thiab L-band (1560nm-1600nm).
Vim tias qhov sib txawv ntawm lub yoj yoj ntawm qhov sib txawv wavebands, kev sib txuas lus yuav cuam tshuam. Yog li ntawd, nws yog qhov tsim nyog los ua kom pom lub dav ntawm qhov txuas ntu fiber ntau. Cov kab xo ua tau tuaj yeem lav qhov kev sib txuas lus ib txwm.
EDFA fiber ntau amplifier tsuas yog ua raws li qhov kev thov no. Nws tuaj yeem siv cov seem fiber ntau raws li qhov nce ntxiv kom ua kom nrov tau cov cim kho qhov muag thiab ua kom dav dav dav (1500nm-1600nm), uas yog txaus los ua kom loj dua qhov siab tshaj plaws cov ntaub ntawv xov xwm channel. Qhov tshwj xeeb no tuaj yeem ua lub luag haujlwm ntau dua hauv WDM multi-channel kho qhov muag, thiab yog li ntawd tau dhau los ua qhov tseem ceeb ntawm WDM system.
Qhov zoo ntawm EDFA fiber ntau amplifier?
Qhov nce ntawm EDFA fiber ntau lub zog ua kom muaj zog. Qhov nce tus nqi ntawm cov fiber ntau tshuab raj yog ib qho ntawm cov ntsuas tseem ceeb. Qhov ua kom zoo dua cov fiber ntau muaj qhov nce ntxiv ntawm 33dB, thaum qhov nce ntawm EDFA fiber ntau zog ntxiv yog li 30-40dB, uas muaj kev nce siab dua.
Lub suab nrov ntawm EDFA fiber ntau lub tshuab ua kom muaj zog me me. EDFA fiber ntau lub zog ua kom nrov nrov ua suab nrov, yog li nws lub suab nrov me dua li qub, feem ntau 4 ~ 7dB.
Tus zaus bandwidth ntawm EDFA fiber ntau amplifier. EDFA fiber ntau lub zog ua kom muaj ntau zaus ntawm 20-40nm ntawm lub nthwv ntawm 1550nm, uas tuaj yeem nqa tawm ntau cov xov tooj xa mus thiab nce lub peev xwm kis tau.
EDFA fiber ntau lub zog ua kom muaj qhov poob qis. Ua hauj lwm nthwv hluav taws xob ntawm EDFA fiber ntau lub zog tsuas yog qhov zoo tshaj yoj yoj rau kev sib txuas lus fiber ntau (1500 ~ 1600nm), uas yog cov chaw poob qis tshaj, yog li poob ntawm EDFA fiber amplifier tsawg thiab kis nrug yog qhov ntev.
Daim ntawv thov ntawm EDFA fiber ntau lub zog
1. Optical fiber thaiv kab ke
2. FTTX, FTTH
3. Dense Wavelength Division Multiplexing (DWDM) kev sib txuas lus kho qhov muag
4. Yeeb yaj kiab kho qhov muag kis tau tus mob thiab CATV
5. Kev sib kis ntev ntawm analog& digital CATV lub teeb liab kho qhov muag
HTF muab ntau qhov ua haujlwm ntawm EDFA optical amplifier modules, lub suab qis, Erbium-Doped Fiber Amplifier (EDFA) cov kev daws teeb meem, cov amplifier modules tuaj yeem ua haujlwm ntawm qhov nce tsis tu ncua (Tsis Siv Neeg Tuaj Tswj AGC), cov khoom siv hluav taws xob tas mus li (Tsis siv neeg lub zog tswj, APC). Integrated VOA tuaj yeem hloov kho kom ua tiav kom tau txais qhov nce qib zoo. Nws tuaj yeem ua kom nrov loj ntawm C-Band cov teeb liab nrog lossis w / o theem nruab nrab nkag (MSA), uas coj zoo yooj rau daim ntawv thov lub network.
Ntau cov qauv kev pabcuam tau txais txhua qhov kev siv lub tshuab ua kom nrov dua hauv qhov txuas txuas ntxiv mus rau qhov txuas ntxiv: koob, nyob hauv-kab, thiab uantejLub rooj zaum ua kom nrov nrovua haujlwm ntawm qhov kis tau tus mob ntawm qhov txuas. Nws muaj lub peev xwm loj ntawm cov hluav taws xob, cov zis hluav taws xob loj, thiab nruab nrab kev tsim kho. Boosters yog tsim los ua kom muaj kev sib koom ua ke ntawm cov khoom siv hluav taws xob ntxiv kom ncav cuag kev ncua ntxiv.
Kev nthuav dav hauv kabua haujlwm hauv nruab nrab ntawm qhov txuas txuas. Nws muaj qhov nruab nrab rau lub zog nruab nrab me me, lub zog tsim hluav taws xob ntau, qhov siab kho qhov muag nce, thiab lub suab qis. Nyob rau hauv kab amplifiers yog tsim rau optical amplification ntawm ob lub nodes sib txuas ntawm lub ntsiab kho qhov muag txuas.
Ib tug pre-amplifierua haujlwm ntawm qhov tau txais qhov kawg ntawm qhov txuas txuas. Nws nta nruab nrab mus rau cov tswv yim hluav taws xob tsawg, nruab nrab cov zis hluav taws xob, thiab nruab nrab Gain. Cov tshuab ntsuas ua ntej tau tsim rau qhov kho qhov muag kom pom tseeb los them cov kev ploj hauv cov demultiplexer uas nyob ze ntawm lub qhov muag txais.
