Kawm txog PON Optical Amplifier

Dab tsi yog qhov kev kho qhov muag tawm?

Tus kho qhov muag amplifier yog ib qho cuab yeej ua kom muaj lub teeb tsa qhov dig muag ncaj qha, tsis tas yuav tsum xub hloov nws mus rau hluav taws xob teeb liab. Ib qho kev kho qhov muag pom tau tias yuav ua rau ib lub laser tsis muaj qhov kab noj ua qhov muag, los yog ib qho uas tawm tswv yim los ntawm cov kab noj hniav yog suppressed. Optical amplifiers tseem ceeb hauv kev sib txuas lus kho qhov muag thiab laser physics.

EDFA CATV FTTH Triple ua si cov khoom siv pob

Muaj ntau ntau lub cev mechanisms uas yog siv los ua kom nrov loj ntawm lub teeb liab, uas sib txuas mus rau cov hom loj ntawm cov khoom siv fais fab. Nyob rau hauv doped fiber ntau amplifiers thiab bulk lasers, stimulated emission nyob rau hauv lub amplifier qhov nce qhov nruab nrab ua amplification ntawm lub teeb tuaj. Nyob rau hauv semiconductor kho qhov muag amplifiers (SOAs), electron-hole recombination tshwm sim. Nyob rau hauv Raman amplifiers, Raman tawg ntawm cov khoom tuaj nrog cov phonons hauv lub lattice ntawm qhov nce qhov tsim tawm photons teeb meem nrog cov khoom xa tuaj. Parametrical amplifiers siv parametric amplification.

FOCC PON Optical Amplifier khoom

FOCC PON optical amplifier series yuav ua tau raws li lub ntsiab FTTx PON Technology. Nws muaj saj zawg zog thiab pheej yig me ntsis rau kev sib tw ua si sib txuas network thiab FTTH (Fibre rau lub Tsev).

Qhov zoo ntawm FTTx Optical Amplifier (tseem hu ua EDFA) yog lub suab qis, kev kawm siab, FTTP siab zog, ntau cov chaw nres nkoj optical amplifier nrog tau nce spectrum band hauv 1540 ~ 1563nm. Txhua lub qhov chaw nres nkoj tawm tswv yim rau optical amplifier tau ua CWDM zoo. Txhua sab nraud qhov txuas qhov chaw nres nkoj ntawm qhov kho qhov muag tau txais kev txuas nrog OLT PON chaw nres nkoj yooj yim heev. Txhua qhov 1550nm (CATV) cov zis qhov chaw nres nkoj optical phab ntsa 1310 / 1490n 's cov ntaub ntawv kwj, kom txo tau qhov ntau ntawm kev tivthaiv thiab txhim kho qhov ntsuas thiab kev ntseeg ntawm lub system.

FTTx PON Optical Amplifier muaj suab tsis tshua muaj suab nrov nrov, tag nrho cov tsev kawm ntawv yuav tsum ua kom muaj kev sib tw rau theem siab, thiab kev ua ntej ua ntej yuav tau txais cov suab nrov tsawg EDFA, qhov tso zis cascade txais tau siab zog EYDFA. Thaum tawm tswv yim optical zog Pin = 0dBm, lub suab nrov ntawm chav tsev yog: Hom ≤4.5dB, Max ≤5.0dB Tsis zoo li lwm yam khoom uas xav tau cov khoom siv hluav taws xob zoo kom muaj suab nrov tsawg.
FOCC EDFA, optical amplifier adopts lub ntiaj teb sab saum toj kawg nkaus twj tso kua mis laser thiab nquag siv fiber ntau. Zoo meej APC, ACC thiab ATC tswj, zoo tsim nyob rau hauv lub qhov cua thiab cua sov-dissipation kom lub neej ntev thiab kev ua haujlwm siab ntawm cov twj laser. RS232 thiab RJ45 muab kev sib txuas rau kev sib txuas thiab SNMP network tswj chaw nres nkoj.

EDFA-1550H LCD nyob rau ntawm lub vaj huam sib luag muaj cov haujlwm ua haujlwm ntawm txhua yam khoom siv thiab ceeb toom ceeb toom. Lub laser yuav hloov tawm tau yog qhov muag fais fab uas ploj lawm, uas muaj kev thaiv kev tiv thaiv rau lub laser. Tag nrho cov chaw nres nkoj kho qhov muag optical amplifier tau muab tso rau hauv lub vaj huam sib luag los yog tom qab vaj huam sib luag.
Nrog kev ruaj ntseg-hoob kawm muaj kev ruaj ntseg thiab kev ruaj ntseg hauv network, kev ruaj siab, kev ntseeg siab thiab zoo heev, EDFA-1550H yog qhov zoo tagnrho FTTx PON Optical Amplifier tov rau system integrators thiab system tus neeg teb xov tooj.
