Ib qho qauv tuaj yeem pab koj yooj yim tuav FOADM, ROADM thiab OXC!
Niaj hnub no, nws coj ib tug qauv: crossroad FOADM, Huandao Road ROADM, subway OXC, los pab sawv daws to taub dab tsi FOADM, ROADM thiab OXC yog dab tsi.
Tom ntej no, nws yuav coj txhua tus los txhais nws kom meej.
FOADM (Fixed Optical Add/Drop Multiplexer, Fixed Optical Add/Drop Multiplexer) ntxiv thiab tee wavelength signals los ntawm cov chaw nruab nrab kom paub txog qhov uplink (kev sib kis), downlink (reception) thiab ncaj nraim ntawm qee lub wavelength signals, thiab txhawb nqa saw lossis nplhaib kev sib koom ua ke.
Rau cov ncauj lus kom ntxaws txog cov teeb liab wavelength, koj tuaj yeem xa mus rau cov tweets yav dhau los txog lub peev xwm loj ntawm cov ntaub ntawv network - WDM / OTN, koj puas nkag siab?
FOADM zoo li txoj kev hla, thiab lub tsheb zoo li lub teeb liab wavelength.
Ntawm txoj kev (xa): Lub tsheb ntsuab tawm ntawm taw tes C sib tshuam rau hauv kev sib tshuam thiab tuaj txog ntawm taw tes B.
Tshem tawm txoj kev (tau txais): Cov tsheb xa los ntawm qhov chaw A mus rau ntawm qhov chaw kuaj xyuas kom muaj xim sib xws (piv txwv li, lub tsheb daj mus hla cov kab daj), thiab tuaj txog ntawm kev sib tshuam los ntawm ib txoj kab tshwj xeeb rau kev sib cais kom ncav cuag C.
Ncaj nraim los ntawm: Tsheb los ntawm taw tes A mus rau ntawm qhov chaw kuaj xyuas xim sib txuam (piv txwv li, tsheb liab mus hla txoj kab liab), thiab ncaj nraim mus rau taw tes B.
Nws tuaj yeem pom tau tias FOADM thev naus laus zis muaj qhov tsis txaus, uas peb suav nrog peb lub ntsiab lus hauv qab no:
1 Cov kis tau tus mob ntawm lub teeb liab wavelength yog tsau, thiab lub tsheb tsuas tuaj yeem siv txoj hauv kev ruaj khov.
2 Lub sijhawm teem caij ntawm cov teeb liab wavelength tsis hloov pauv txaus, thiab kev sib tshuam tsis tuaj yeem taug kev random.
3 Lub sijhawm teem caij ntawm lub teeb liab wavelength yuav tsum tau hloov kho ntawm cov khoom siv kho qhov muag, thiab lub tsheb yuav tsum ua raws li txoj kev npaj.
Txhawm rau daws peb qhov tsis txaus ntawm FOADM, ROADM thev naus laus zis tau hloov zuj zus.
ROADM (Reconfigurable Optical Add/Drop Multiplexer, reconfigurable optical add-drop multiplexer) tuaj yeem hloov kho cov teeb liab wavelength, dynamically muab qhov ntxiv, poob lossis dhau-dhau ntawm txhua lub teeb liab wavelength, thiab paub lub sijhawm hloov pauv ntawm cov teeb liab wavelength. Mesh networking.
ROADM zoo li txoj kev nyob ib ncig ntawm cov kob, thiab cov tsheb zoo li lub teeb liab wavelength.
ROADM tuaj yeem teem caij tsheb thauj mus los ntawm txoj kev ncig mus ncig, kom cov tsheb xa los ntawm taw tes A coj mus rau ib qho kev sib kis thiab tuaj txog ntawm txhua qhov kev taw qhia ntawm B / C / D / E / F, paub txog kev teem sijhawm ntawm cov teeb liab wavelength.
Pom tseeb, ROADM txuas ntxiv txhim kho qhov hloov pauv ntawm kev teem sijhawm ua lag luam thiab coj peb cov txiaj ntsig loj hauv qab no:
ROADM txhawb nqa qhov kev txiav txim siab ntawm cov teeb liab wavelength.
ROADM txhawb lub sijhawm hloov pauv ntawm cov teeb liab wavelength hauv ntau cov lus qhia.
ROADM tshem tawm ntau qhov kev hloov kho fiber ntau, txhim kho O&M efficiency thiab txo cov nqi khiav lag luam.
Txawm hais tias ROADM daws qhov teeb meem ntawm FOADM zoo heev, ob qho tib si ROADM thiab FOADM thev naus laus zis xav tau cov laug cam kom txuas los ntawm lub cev kho qhov muag fibers, uas yuav ua rau muaj ntau cov fibers optical thiab kev sib txuas. Txhawm rau daws qhov teeb meem ntawm fiber ntau optical, OXC thev naus laus zis tau qhia.
OXC (Optical Cross Connect) yog ua raws li qhov kho qhov muag rov qab platform, yog li cov teeb liab wavelength tuaj yeem sib txuas los ntawm lub dav hlau kho qhov muag, thiab kev sib txuas hauv fiber ntau tuaj yeem ua tiav raws li qhov kho qhov muag backplane.
OXC zoo li lub tsheb ciav hlau subway, thiab lub teeb nraub qaum yog zoo li ib qho kev sib txuas hauv av subway network. Tau kawg, txoj kev subway network ntawm OXC yog qhov nyuaj dua, thiab nws tuaj yeem paub qhov kev sib tshuam ntawm ob lub ntsiab lus.
OXC ua tiav qhov kev sib txuas ntawm lub cev kho qhov muag fiber ntau los ntawm txoj kev subway network, kom cov boards ib leeg tuaj yeem sib txuas ncaj qha los ntawm lub dav hlau optical backplane, paub txog "0" nrog fiber ntau txuas.
OXC thev naus laus zis yog ua raws li ROADM thev naus laus zis thiab qhia txog qhov kho qhov muag rov qab platform kom paub txog "0" kev sib txuas hauv fiber ntau, uas ua rau muaj txiaj ntsig zoo ntawm kev ua haujlwm thiab kev saib xyuas.
