ROADM yog lub rooj vag ntawm tag nrho cov-optical network
Ib qho ntawm cov thev naus laus zis tseem ceeb. Nws lub hom phiaj tseem ceeb yog kom paub ntxiv txog "photonicization" (optical switching) ntawm nodes raws li "photonicization" ntawm kab.
ROADM hloov mus rau CDC-F ROADM, uas pib paub txog qhov muaj peev xwm hloov kho qhov muag muaj zog heev. Txawm li cas los xij, nws tseem tsis yog tag nrho-optical
Qhov kawg daws.
Muaj qee qhov teeb meem nrog ROADM. Ib qho teeb meem loj tshaj plaws yog qhov nyuaj ntawm kev sib txuas cov fibers
ROADM system architecture
ROADMs feem ntau txuas optical fibers ib qho los ntawm ib qho raws li kev nthuav dav ntawm cov kev pabcuam. Kev npaj yuav hloov raws sijhawm
Yog tias lub network xav tau hloov kho, lossis lub network yuav tsum tau hloov kho, qhov kho qhov muag fiber ntau yuav txuas ntxiv ntxiv.
Sij hawm dhau mus, kev sib txuas ntawm fiber ntau dhau los ua chaotic, uas ua rau muaj kev nyuaj rau kev ua haujlwm thiab kev saib xyuas. Nrog ROADM, tus naj npawb ntawm racks kuj siab dua
Ntxiv, siv ntau qhov chaw.
Yog li ntawd, qhov zoo dua thiab tsim nyog rau txhua qhov kev hloov kho qhov muag tau coj mus rau ua ntej, uas yog, OXC.
OXC, lub npe tag nrho yog optical cross-connect, optical cross-connect.
Zoo li ROADM, OXC kuj yog ib qho khoom siv kho qhov muag uas tuaj yeem hloov kho qhov muag pom ntawm qhov sib txawv ntawm txoj kev kho qhov muag.
Lub tswv yim ntawm OXC yeej muaj nyob ib ncig ntawm 2000. Hauv kev nkag siab, ROADM yog qhov tshwj xeeb ntawm OXC
Rau kev siv tshwj xeeb, OXC suav nrog ROADM.
Los ntawm qhov kev xav ntawm kev tsim qauv ib txwm muaj, OXC yog tsim los ntawm cov qauv xws li optical cross-connect matrix, input interface, output interface, thiab tswj chav tswj.
ua. Optical cross-connect matrix yog lub hauv paus ntawm OXC.
