Oct 30, 2025|
Ib Leeg -} hom - Coaster Option Option Option Waser 9- micron micrron fiber ntau. Cov qauv no cia siab rau Laser Technology tsis yog LEDs vim tias tsuas yog lasers tuaj yeem tsim cov txheej txheem, nqaim} ceev cov ntaub ntawv xa tawm ntau hom fiber ntau.
Cov Qauv Ua Haujlwm Tseem Ceeb: Kev Hloov Pho Yees
Kev hloov kho kho qhov muag ua haujlwm los ntawm ob qho txheej txheem synchronized nyob rau hauv cov qauv compact. Cov xov tooj hloov kho kho kho tau- kev sib dhos (TOSA) muaj cov hluav taws xob lim hluav taws xob rau hauv lub teeb.
Lub Laser Diode ua hauj lwm dhau los ntawm semiconductor physics. Thaum hluav taws xob tam sim no ntau tshaj qhov theem pib, hluav taws xob hauv cov khoom siv semiconductor tawm koob tshuaj tiv thaiv kev txhawb nqa. Lub laser yuav tsum muaj DC kev tsis ncaj ncees tam sim no ntau dua li qhov pib tam sim no los tawm ntawm lub teeb tseem ceeb tshaj no qhov pib tsim tawm ntawm laser. Qhov kev tswj hwm no ua rau muaj kev nrawm rau- tawm kev tawm tswv yim tsim nyog rau cov ntaub ntawv xaiv cov ntaub ntawv teeb pom kev zoo li lub teeb pulses.
Vim li cas lasers yog qhov tseem ceeb rau ib qho -} hom kev kis
Ib Leeg - hom {{1} {}} txuas rau ib qho me me ...}} txuas rau tsuas yog ib hom teeb kom propagate. Qhov kev hloov pauv no nrog lasers ua haujlwm thaum lub sij hawm ntev ntev nrog cov chaw me me loj loj loj loj-loj thiab nqaim lub ntsej muag dav. LED cov chaw siv nyob rau hauv multipde transceivers tsis tuaj yeem ua tiav qhov precision no.
Ib Leeg -} Txoj kev hloov pauv ib txwm ua haujlwm Laser), lossis EMNY- Cov Khoom Siv Hluav Taws Xob), kev ua haujlwm lossis 1550nm Wavel. Cov wavelengths no tau xaiv vim muaj fiber ntau optic Apenuation ncav cuag qib tsawg kawg ntawm cov ntsiab lus tshwj xeeb hauv infrared spectrum.
Lub laser ntawm cov kev sib koom ua kom muaj kev sib txuam nqaj hlau ua rau lub cev nqaij daim tawv ntawm ib qho {{hom fiber fiber ntau dua. Coupling efficiency ntawm ib qho {{2} hom kev ua haujlwm, cov tsov ntxhuav yog suav nrog cov qauv siv kho dua tshiab
Laser hom thiab kev sib nrug deb
Cov thev naus laus zis ua haujlwm tau cov kev yuav tsum muaj cov kev yuav tsum muaj:
Fabry - pej (FP) lasers: Cov theem pib kab noj hniav ua haujlwm zoo rau luv dua ib leeg {{0} hom ntawv thov txog 40km. Ib qho raug 1310nm FP laser hloov pauv pseudo emitter Couplic (PECL) hluav taws xob piav qhia rau hauv Circuit Court hauv lub tshuab xa khoom.
Faib cov lus (DFB) lasers: DFB lasers muab cov khoom ruaj khov thiab txoj kab nqaim, ua rau lawv muaj kev cuam tshuam ntev fiber ntau, ua rau lawv zoo tshaj plaws rau kev xa cov ntawv thov ntev. Cov lasers dominate kasro thiab ntev - haul networks ua haujlwm dhau 40km.
Sab nraud hloov kho lasers (EML): Rau Ultra -}}}}}}}}} long long} long,, rho tawm chirp thiab ua kom muaj zog ntau dua nrog cov teeb liab qis teeb meem.
Lub fiber ntau cov kev sib tw
Hloov cov teeb laser laser rau hauv 9-micron fiber ntau dua cov khoom lag luam tseem ceeb cov kev sib tw. Raws li network nrawm ntxiv thiab photodiode cov chaw nquag txiav, coupling ua ntau dua li 20 microns, yuav tsum tau ua kom pom tseeb tsis meej txog kev tsom iav ntawm lub cev.
Raug txuas ntxiv txuas rau laser dieres rau ib qho {} {{2} {{{{{4 4}} Infrared ntau. Lub Coupling txheej txheem siv precision optics ntawm lub laser thiab fiber los ua cov nqaj profile thiab ua kom nruj dua.
Cov kev ua kom muaj kev tsim kho yog qhov sib zog tshwj xeeb. Lwm yam cuam tshuam nrog txuas nrog rau kev ua yuam kev, thiab txoj kev sib cav sib ceg ntev, thiab kev siv lub kaum kev ua yuam kev ntev, txhua yam uas yuav tsum tau tswj tau thaum lub sijhawm tsim khoom. Niaj hnub siv cov tshuab automated niaj hnub siv cov tswv yim nquag los ua kom tau zoo txuas ntawm cov sib dhos.
Wavelength Xaiv thiab WDM Technology
