Tus naj npawb ntawm cov khoom siv waveguides yuav tsum xyuas kom meej tias txhua qhov xwm txheej tsis sib xws muaj peev xwm sau tau, uas yog, cov zauv ntawm lub teeb tsa ntawm qhov sib xyaw waveguide loj dua cov lus tawm thiab cov khoom tawm waveguides Yog, kom lub teeb ntawm lub tswv yim waveguide tuaj yeem xa mus rau cov zis waveguide yam tsis muaj qhov ntxeev (los yog hais me me). Cov kab ke ntom ntom ntom ntom ntom ntom muaj qhov sib thooj ntev sib txawv, thiab feem ntau tau tsim los ua qhov sib txuam ntawm ntau qhov ntev ntawm lub cev nthwv dej rau lub nruab nrab nthwv dej.
AWG ua haujlwm li cas?
Arrayed waveguide grating (AWG) feem ntau yog tsim ntawm N tswv yim waveguides, N tso tawm waveguides, 2 N * M slab waveguide lub hnub qub txuas thiab ib qho M waveguide slab arrayed waveguide grating, qhov twg M tuaj yeem sib npaug rau N lossis tsis N. Qhov kev sib tsoo no muaj cov kab tas mus li qhov ntev sib txawv ntawm sib luag waveguides.
Lub ntsiab tseem ceeb ntawm AWG
1. Tso tsis tau IL
Cov tsis nkag ntawm cov channel ntawm AWG lim tau txhais tias ITU-T coj mus rau lub zog kho qhov muag tsis pom qhov nkhaus (suav nrog qhov ntau thiab qhov tsawg tshaj plaws kho qhov muag pom hluav taws xob tsis txaus) nyob rau hauv cov kev ua haujlwm ntawm cov kev ntsuas kub thiab qhov yam ntxwv pom tias yog qhov poob ntau tshaj plaws tus nqi tsis pub dhau tus tshaj tawm channel, qhia hauv dB.
AWG lim tsis nkag: qhov siab tshaj ntawm cov teeb meem tsis nkag rau hauv txhua cov channel ntawm AWG, qhia nyob rau hauv dB.
2. bandwidth
Bandwidth muaj -0.5dB, -1dB, -3dB, -20dB bandwidth, thiab lwm yam. Cov bandwidth ntawm ib channel yog qhov sib cuam tshuam ntawm 0.5dB, 1dB, 3dB, 20dB thiab lub zog kho qhov muag poob los ntawm qhov txiav tawm ntawm qhov tsawg kawg ntawm cov fais fab tuag. nkhaus ntawm cov channel nqes Qhov dav ntawm. Thaum xam xyuas qhov bandwidth, nws yog qhov tsim nyog los xav txog cov yam ntxwv polarization, thiab coj tus nqi tsis zoo tshaj plaws nyob rau ntau lub xeev polarization." -X dB" kev siv bandwidth yog feem ntau hu ua" X dB" bandwidth.
Qhov zoo ntawm kev siv AWG wavelength faib multiplexer
Tam sim no, kev siv WDM thev naus laus zis los txhim kho kev siv tus nqi ntawm cov roj carbon fiber ntau thiab daws cov kev xav tau ntawm cov chaw nres tsheb hauv thaj chaw uas cov optical fiber yog tsis tshua muaj kev daws teeb meem zoo tshaj plaws tau lees paub hauv kev lag luam. Tab sis txawv WDM thev naus laus zis kuj tau teb rau cov sib txawv network. CWDM tsis tshua muaj nqi, me me hauv kev pib nqis peev, tsim nyog rau kev siv thawj zaug, tab sis nws tsis yooj yim kom tau raws li cov kev xav tau ntawm kev txhim kho mus ntev thiab kev saib xyuas yooj yim ntawm 5G fronthaul. Ntau cov cuab yeej ua haujlwm DWDM zoo dua li AWG tuaj yeem ua lub luag haujlwm hauv kev tsim kho ntawm 5G fronthaul tes hauj lwm, txo cov kev ua kom tsis muaj qhov tsis zoo ntawm kev tsim kho.
HTF yog qhov kev lag luam ua haujlwm siab rau cov khoom lag luam tsim kho rau WDMsolution, kho qhov muag, thiab MPO / MTP thaj qaum.
Hais txog kev siv thev naus laus zis, nws khaws nrog lub lag luam sib tw, thiab sib zog los tsim qhov zoo tshaj plaws ua ntej tshaj tawm cov khoom siv sib txuas lus kho qhov muag. Nyob sab hauv, peb nruj me ntsis raws cov qauv thoob ntiaj teb zoo rau kev tswj hwm, txhim kho kev tsim khoom, thiab tsom mus rau kev txhim kho kev paub zoo thiab kev ua tau zoo ntawm txhua tus neeg ua haujlwm, txhim kho kev ua tau zoo thiab ua kom cov khoom zoo.
