Cov kev siv ua lag luam yog dab tsi?SOA optical amplifiers?
SOAsemiconductor optical amplifieryog ib lub cuab yeej sib txuas PN siv cov qauv quantum zoo. Qhov kev cuam tshuam sab nraud ua rau muaj kev hloov pauv ntawm cov khoom me me, thiab lub teeb sab nraud ua rau muaj kev cuam tshuam hluav taws xob, ua rau muaj kev ua kom pom tseeb ntawm lub teeb liab. Qhov zoo: Txhawb nqa kev kub ceev, bandwidth siab, kev siv hluav taws xob tsawg, nce siab, miniaturization, thiab kev sib koom ua ke yooj yim. Qhov tsis zoo: kev hloov pauv hla kev nce thiab kev sib cuam tshuam tsis sib xws ntawm cov channel wavelength sib txawv, kev rhiab heev polarization, nce saturation. Piv nrog EDFA optical amplifiers (erbium-doped fiber amplifiers), qee cov ntsuas ntawm cov khoom siv lag luam tsis muaj zog dua liEDFA optical amplifiers, tab sis SOAcov khoom siv kho qhov muagtseem muaj cov yam ntxwv uas EDFA optical amplifiers tsis tuaj yeem hloov tau. Yog tias nws tuaj yeem txhawb nqa O-band (1260-1360), E-band (1360-1460), L-band (1460-1530) amplification, thiab muaj cov yam ntxwv ntawm tus nqi qis, me me thiab yooj yim kev koom ua ke, nyob rau hauv lub sijhawm tshiab ntawm kev tsim kho vaj tse, SOA optical amplifiers yuav nyob hauv lub network nkag mus thiab ntug ntawm MAN, nrog rau lub teb pom kev fiber ntau kom tau txais cov ntawv thov loj.
Daim ntawv thov kev lag luam ntawm SOA optical amplifier
Nrog kev txhim kho ntawm kev ua tau zoo ntawm SOA optical amplifier xws li cov zis optical zog, me me teeb liab nce, nce polarization rhiab heev thiab suab nrov index, SOA amplifier yuav ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus network thiab sensor networks. Ntxiv rau SOAcov khoom siv kho qhov muaguas tuaj yeem ua tau raws li qhov kev ua kom loj ntawm 1310 nm band,Cov amplifiers SOAtuaj yeem hloov EDFA amplifiers tag nrho hauv qee qhov chaw ua kom muaj zog ib theem ntawm 1550 nm band.
1. Lub network kis tau tus mob optical
Nrog kev tsim kho ntawm 5G network, qhov kev thov bandwidth nce siab, thiab 100G (4 * 25G CWDM4 / LWDM4) kev sib kis ceev ceev yog qhov xav tau ntawm ntug ntawm kev nkag mus rau hauv network thiab thaj chaw hauv nroog, thiab qhov kev sib kis ntawm ntug ntawm lub nroog thiab lub nroog, kev nkag mus rau hauv network thiab thaj chaw hauv nroog feem ntau yog 5km-40km. Hauv qhov xwm txheej xa mus rau pem hauv ntej ntawm 5G chaw nres tsheb, hauv qee qhov chaw nres tsheb uas nyob deb, optical modularSOA ntaus ntawvsiv tau los txhim kho qhov optical power margin, thiab paub txog qhov kev hloov pauv qis ntawm 25G teeb liab ntawm lub hauv paus chaw nres tsheb hauv 1310 nm band thiab 1550 nm band. Hauv daim ntawv thov ntawm lub network cab kuj, lub SOA amplifier tuaj yeem koom ua ke rau hauv ROSA lossis TOSA ntawmmodule kho qhov muag amplifier, los yog lub cuab yeej SOA ywj pheej los yogSOA optical modulesiv tau rau kev ua kom nrov dua.
2. Kev nthuav dav ntawm spectral ntawm kev saib xyuas network
Tam sim no, nrog rau kev loj hlob sai ntawm kev lag luam cov ntaub ntawv, qhov kev thov rau kev saib xyuas cov ntaub ntawv streaming hauv kev ua lag luam maj mam nce ntxiv, uas feem ntau yog nyob rau hauv lub hauv paus network node rau kev saib xyuas spectral, lub teeb liab feem ntau tsis muaj zog, qhov xav tau siv optical amplifier, thiab 100G lag luam muaj ntau ntawm 1310 wavelength, tsuas yog tuaj yeem ua kom nrov dua los ntawm SOA ntaus ntawv. Qhov no kuj yog qhov siv dav tshaj plaws thiab paub tab ntawm SOA amplification tam sim no.
3. DCI rau kev sib txuas ntawm cov chaw khaws ntaub ntawv
Nrog rau kev txhim kho ntawm cov ntaub ntawv loj, qhov kev thov rau kev sib txuas lus bandwidth siab ntawm cov chaw khaws ntaub ntawv maj mam nce ntxiv. Rau cov kev pabcuam ceev ceev, lub cuab yeej SOA tuaj yeem siv rau kev ua kom lub teeb liab optical relay amplification, ua rau qhov txuas optical fais fab margin thiab txuas ntxiv qhov kev sib kis. SOA amplifiers tuaj yeem siv rau ob qho tib si 1310 band thiab 1550 band high-speed kev pabcuam teeb liab optical amplification. Lub khw no feem ntau siv stand-aloneSOA semiconductor optical amplifiers(cov khoom siv uas tau teeb tsa rau ntawm lub rack).
4. Kev siv cov khoom siv fiber optic faib tawm thiab LiDAR system
SOA optical modules muaj cov yam ntxwv teb zaus zoo heev thiab qhov sib piv siab, thiab siv tau ua cov hloov kho qhov muag lossis modulators. Nrog kev txhim kho tas mus li ntawm SOA thev naus laus zis, AOM modulators tuaj yeem hloov pauv hauv feem ntau qhov xwm txheej ntawm kev siv fiber ntau optical sensing kom tau txais laser pulse nqaim nrog qhov sib piv siab.
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev tsav tsheb ntse thiab kev sib koom tes ntawm tsheb thiab txoj kev, LiDAR tau siv dav hauv ob qho tib si tsheb thiab ntawm ntug kev. Vim yog qhov me me thiab qhov nce siab ntawmSOA optical amplifier module, nws tuaj yeem siv rau hauv LiDAR kom tau txais cov kab laser nqaim thiab txhim kho lub zog kho qhov muag siab, tshwj xeeb tshaj yog cov khoom siv optical chip Lidar ntawm tiam tom ntej ntawm cov thev naus laus zis FMCW hauv zos, uas yog daim ntawv thov dav dua ntawm yav tom ntej SOA optical amplifier.
