Ultra-High-Power Optical Amplifier rau FTTH - EYDFA
Tom qab
Thaum lub Cable Modem, xDSL, thiab lwm yam kev siv broadband nkag tau ntau xyoo dhau los, Fiber Rau Lub Tsev (FTTH) kev nkag los kuj maj mam ua ib qhov project uas tib neeg nyiam heev. Lub FTTH yuav pom tseeb tias "peb tes hauj lwm hauv "ib qho" ntawm Xov Tooj, CATV thiab Internet, thaum tus ceev cov ntaub ntawv xa tawm tuaj yeem tshaj 100 Mbps (200 npaug tawm sai dua qhov siv xov tooj xa mus) thiab nqa vaj tse siab ua yeeb yaj kiab thiab ua haujlwm online. FTTH tseem daws tau qhov teeb meem xws li kev siv xov tooj hu, lub ntsiab lus ntawm lub TV thiab lwm yam.
Los ntawm cov seem ntawm lub ntiaj teb qhov teeb meem, lub FTTH txoj kev txhawb nqa ntawm South Kauslim thiab Nyij Pooj tau nkag mus rau lub caij nyoog kev loj hlob sai; North America thiab Europe tau pib pib uas ua rau muaj kev pom zoo zoo; Tuam Tshoj, Russia, Is Nrias teb thiab South America yog tom qab thiab tsiv txoj kev loj hlob. Los ntawm cov kev xav ntawm FTTH, qhov kev sib txuas kev lag luam kev lag luam hauv kev lag luam loj hlob kuj tseem loj heev.
Daim ntaub ntawv ntawm High-Power Optical Amplifiers
High-power optical amplifier ua ib qho ntawm cov khoom siv yooj yim ntawm kev sib txuas lus niaj hnub, tsis yog tsuas yog lub hauv paus ntawm qhov muaj peev xwm loj thiab kev sib txuam txhua qhov kev sib txuas lus, tab sis kuj yog ib qho tseem ceeb thiab muaj feem tseem ceeb hauv txoj haujlwm ntawm cov kabmob fiber ntau 'pheej txuas ntxiv thiab nthuav tawm. Tam sim no, nyob rau hauv central chaw ua hauj lwm, nws feem ntau yuav tsum nruab ib qho ntau dua ib qhov kev kho qhov muag kom thiaj li yuav tau them loj dua thiab ntau cov neeg siv. Yog xav tau CATV, piv txwv tias, yog ib lub nroog loj uas yuav tsum tau xa cov xov xwm zoo tshaj plaws hauv TV thawj zaug rau lub zos thiab cov zos, nws feem ntau xav tau 4 txog 8 teev ntawm cov khoom siv kho qhov muag. Txawm li cas los xij, yog tias siv lub tshuab fais fab loj siv zog, ces tsuas yog ib qho txaus, uas tuaj yeem txo nqi.
Cov Kev Ntsuas Ntawm Cov Hluav Taws Xob Pom Zoo Txuj Ci
Tsoos Tshuaj Siv EDFA Technology
Ib qho ntawm cov tswv yim rau kev siv hluav taws xob siab tshaj plaws yog siv cov tshuaj EDFA cov kev cai tam sim no. Raws li pom nyob rau hauv daim duab hauv qab no, qhov teeb meem yog pib ntawm thawj theem thiab ces muab faib ua ntau qhov chaw mus rau ntau lub EDFAs ntawm tus thib ob theem kom paub qhov ntxiv qaum zog. Lub hwjchim loj kawg ntawm qhov kawg yuav raug faib.
Theare yog plaub feem ntau ntawm cov tshuaj no:
Qhov kev saws me nyuam ntawm ntau tus qauv yuav ua rau cov qauv kho qhov muag nyuaj heev, thiab vim yog muaj ntau cov lasers hauv sab hauv, qhov kev tswj coj tus qauv yog qhov nyuaj heev.
Raws li cov qauv hauv multilevel muaj WDM ntawm ob theem ntawm qhov kho qhov muag amplifiers, sib npaug los coj qhov chaw poob ntxiv rau txoj kev kho qhov muag, lub suab nrov nrov ntawm EDFA amplifiers yuav tsis zoo.
Ntxiv mus, cov tshuaj EDFAs siv ib hom tshuab fiber ntau hauv tshuab fais fab, tab sis high-power ib hom pumped lasers tau zoo heev rau kev fais fab thiab nqi.
Tag nrho cov nyiaj hauv EDFA tus nqi yog siab heev thiab kim heev.
Siv tshuaj zoo dua EYDFA Technology
Lub tshuab hluav taws xob (ultra-high-power amplifier) yog lub tshuab tshuab Multimode cladding tshuab-EYDFA, ib cov qauv siv tshiab uas siv cov Yb3 + thiab Er3 + ions doped double-clad fiber. Cov cuab yeej siv tau los ua ke ntawm cov kev yees duab tshiab, cov txheej txheem tshiab thiab cov ntaub ntawv tshiab. Nws yog cov cuab yeej technology ntawm ultra-high-power amplifiers thiab nruab nrab yog cov kev coj ntawm kev xav ntawm optical amplifier yees. Thaum siv EDFA ib txwm siv tshuab ib hom fiber ntau hauv tshuab hlwb hlau kom ua tau ntau dua rau cov khoom siv hluav taws xob (uas tau ua dhau los ntawm cov khoom thiab cov nqi), Er / Yob-Doped Fiber Amplifier (EYDFA) multimode cladding twj tshuab output zog fais fab amplifiers. Ntawm no yog cov qauv kho qhov muag ntawm EYDFA.
Lub ntsiab zoo ntawm EYDFA yog li nram qab no:
Piv nrog ib hom fiber ntau hauv tshuab hlwb hlau, multimode cladding twj siv tshuab muaj kev pom zoo. Kev siv tshuab multimode cladding tshuab yog los tawm tswv yim rau lub twj tso kua mis rau cov multimode ob-cladding fiber ntau uas nws kauj phuam yog pua pua txhiab lub sij hawm ntawm ib hom fiber ntau. Yog li ntawd, thaum tib lub tswv yim optical ntom, multimode cladding twj tso cai rau pua pua txhiab lub sij hawm ntawm ib hom pumped cov tswv yim, yooj yim realizing qhov kho siab amplifiers lub siab tso zis zog los yog ultra-siab tso zis zog.
Yuav tsum paub siv cov qauv yooj yim kho qhov muag, yog li daim ntawv thov yog yooj yim heev (raws li qhia hauv daim duab hauv qab no).
Tag nrho tus nqi ntawm cov twj yuav ua tau zoo heev.
FOCC's high-power optical amplifier module yam khoom-FTTH-EYDFA series yog featured nrog cov zis muaj zog (17-26 dBm), tsis tshua suab nrov (tsawg dua 6 dB @ 1550 nm, 5 dBm input fais fab), ntau ntawm kev ua hauj lwm wavelength (1540-1565 nm), yoog raws kev tswj, muaj kev cia siab, thiab lwm yam. Qhov tso zis fais fab ntawm high-power optical amplifier nyob ze ze 32 dBm hauv txoj kev sim.
Xaus
Predictably, ntau daim ntawv sau npe ntawm ultra-high-power optical amplifiers (EYDFA) yuav muaj feem xyuam rau kev tsim kho kev sib txuas lus, thiab nws txoj kev ua lag luam thiab kev ua tau zoo rau kev coj noj coj ua thiab kev sib raug zoo.
