OXC, lub npe tag nrho yog 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 rau thaum ntxov li ntawm 2000. Hauv kev nkag siab, ROADM yog ib qho tshwj xeeb ntawm kev siv OXC, thiab OXC suav nrog ROADM.
Los ntawm qhov kev xav ntawm ib txwm siv architecture, OXC yog tsim los ntawm optical cross-connect matrix, input interface, output interface, tswj chav tswj thiab lwm yam modules. Optical cross-connect matrix yog lub hauv paus ntawm OXC. Lub npe hu ua matrix tiag tiag yog "lub thawv" nrog txhua qhov chaw nres nkoj sab hauv sib cuam tshuam hauv khub.
Peb yuav piav qhia nrog lub architecture ntawm Huawei's OXC cov cuab yeej.
Cov khoom siv OXC feem ntau yog tsim los ntawm cov khoom siv kho qhov muag, kho qhov muag backplanes thiab kho qhov muag tributary boards.
Feem ntau hais lus, txhua qhov ntawm lub rooj tsav xwm Circuit Court sib raug rau ib qho kev taw qhia. Tom qab lub teeb liab kho qhov muag nkag, nws yog "disassembled" rau hauv N wavelength signals los ntawmWSS (Wavelength Selective Switch).
Yav dhau los WSS keyboards siv MEMS mechanical architecture. Cov qauv no muaj qhov tsis ua haujlwm siab thiab tsis muaj kev ntseeg siab. Tom qab ntawd, nws tau hloov mus rau hauv LCoS (kua siv lead ua ntawm silicon), uas ib txwm txhawb nqa Flexi-Grid muaj nuj nqi, txhawb kev sib txawv ntawm cov channel dav thiab cov channel super, thiab muaj kev ntseeg siab ntau dua.MEMS.
Raws li txoj cai, LCoS cov kev daws teeb meem siv cov theem tswj lub wavelength xaiv, tsis muaj kev vibration, tsis muaj optical amplification rau sab sauv thiab sab nthwv dej, thiab kev taw qhia qhov ntev txog li 32 qhov ntev, ua tiav super loj crossover muaj peev xwm thiab qis zog noj.
Lub wavelength optical teeb liab dhau los ntawm optical connector thiab nkag mus rau optical backplane los ntawm optical circuit board.
Optical backplane yog qhov sib txawv tseem ceeb ntawm OXC thiab ROADM, thiab muaj cov ntsiab lus siab. Nws yog sib npaug rau luam tawm ntau cov fibers kho qhov muag ntawm ib daim ntawv kom paub txog kev sib txuas ntawm qhov muag.
Lub optical backplane muab kev txhawb nqa loj hloov peev xwm thiab nanosecond ncua.
Tom qab lub wavelength optical teeb liab tawm ntawm lub qhov muag rov qab, nws nkag mus rau hauv lub rooj tsav xwm kho qhov muag, thiab ib qhoN × M NWSyog tsim los ntawm kev ntxiv ib theem ntawm LCoS siv lead ua dav hlau hloov.
