EDFA (Erbium-doped Optical Fiber Amplifier)
EDFA yog qhov tseem ceeb rau lub twj tso kua mis kho qhov muag uas nqus tau lub zog ntawm lub teeb lub taub.
EDFA (Erbium-doped Optical Fiber Amplifier), uas yog erbium-doped fiber ntau lub suab nrov, yog ib yam khoom siv kho qhov muag uas ua kom nrov loj lub teeb liab. Lub luag haujlwm tseem ceeb yog los ua lub zog them nyiaj ntawm lub teeb liab teeb liab hauv qhov txuas kis.
Vim li cas siv EDFA: Kev xa mus poob thiab cov hluav taws xob ntawm cov kis hluav taws xob txwv tsis pub dhau qhov sib kis ntawm lub teeb liab kho qhov muag, yog li nyob rau hauv kev sib kis ntev, chaw nres tsheb relay (kho qhov muag ntxiv) yuav tsum tau ntxiv txhua qhov kev ncua deb. Los xyuas kom meej qhov kis tau tus mob zoo.
Cov txheej txheem tsim hluav taws xob ntawm EDFA yog rau dope erbium ions nyob rau hauv cov khoom tseem ceeb silica ntawm qhov kho qhov muag fiber, thiab muab lub twj tso kua mis cais tawm sab nraud, kom cov erbium ions hauv cov tub ntxhais yog" tsa" los ntawm lub twj tso kua mis lub teeb, thiab lub zog qib Lub photon tso tawm los ntawm kev hloov pauv; EDFA optical amplifier yog qhov tseem ceeb tib yam li laser. Lub teeb tsa los ntawm lub laser yog lub teeb tsim tawm los ntawm cov khoom nce ntxiv hauv cov resonator, thiab cov suab nrov nthuav dav ntxiv lub zog nkag los ntawm sab nraud.
Tus qauv yooj yim ntawm EDFA:
EDFA kuj tuaj yeem txuas nrog hauv cov yeeb yaj kiab rau kev ua kom muaj zog.
Vim tias EDFA kuj yog qhov tseem ceeb fiber ntau, qhov sib txuas nrog cov hluav taws xob kho qhov muag kuj yog qhov yooj yim, uas yog, cov kev sib txuas ua ke tau siab.
Qhov zoo ntawm EDFA yog qhov ua haujlwm qis wavelength ploj, kev ua haujlwm loj bandwidth, siab nce, thiab lub suab qis.
Qhov tsis zoo ntawm EDFA yog tias nws tsuas tuaj yeem ua kom lub teeb ci hauv 1550nm band.
