Tsis ntev los no, Tuam Tshoj Academy of Telecommunication Research, ua ke nrog ZTE Corporation Limited thiab Changfei Optical Fiber thiab Cable Co., LTD. (tom qab no hu ua "Changfei Company") raws li ib hom quartz fiber ib txwm muaj, ua tiav S + C + L ntau-band loj-muaj peev xwm kis tau tus mob, qhov siab tshaj plaws ntawm ib-yoj tus nqi tau mus txog 1.2Tbit / s, thiab ib-kev taw qhia kis tus nqi ntawm ib qhocov fibertshaj 120Tbit/s. Teem ib qho ntaub ntawv tshiab rau lub ntiaj teb rau qhov kev xa xov tiag tiag ntawm cov fiber ib hom, sib npaug rau kev txhawb nqa kev xa ntau pua zaj yeeb yaj kiab siab 4K lossis ntau cov ntaub ntawv qhia txog AI ib ob.
Raws li cov lus ceeb toom, qhov kev sim pov thawj ntawm ib-fiber unidirectional super 120Tbit/s tau ua tiav cov txiaj ntsig zoo hauv qhov dav spectrum ntawm lub kaw lus, cov algorithms tseem ceeb thiab kev tsim qauv vaj tsev.
Hais txog qhov dav ntawm lub cev spectrum, raws li C-band ib txwm muaj, qhov dav ntawm lub cev spectrum tau nthuav dav ntxiv mus rau S thiab L bands kom ua tiav qhov kev sib txuas lus loj heev ntawm S + C + L multi-band txog li 17THz, thiab qhov ntau ntawm band npog 1483nm-1627nm.
Hais txog cov algorithms tseem ceeb, Tuam Tshoj Academy of Telecommunication Research muab cov yam ntxwv ntawm S/C/L peb-band optical fiber poob thiab hloov pauv fais fab, thiab tawm tswv yim ib txoj kev npaj los ua kom muaj txiaj ntsig zoo tshaj plaws los ntawm kev sib phim ntawm tus nqi cim, channel interval thiab modulation code hom. Tib lub sijhawm, nrog kev pab los ntawm ZTE's multi-band system filling wave thiab automatic power balancing technology, kev ua haujlwm ntawm channel-level service yog sib npaug thiab qhov deb kis tau zoo tshaj plaws.
Hais txog kev tsim qauv vaj tsev, qhov kev sib kis tiag tiag siv cov thev naus laus zis photoelectric sealing thev naus laus zis hauv kev lag luam, qhov baud rate ntawm ib nthwv dej tshaj 130GBd, qhov bit rate ncav cuag 1.2Tbit / s, thiab tus lej ntawm cov khoom siv photoelectric tau txuag tau zoo heev.
Qhov kev sim no siv cov khoom siv fiber ntau ultra-low attenuation thiab thaj chaw ua haujlwm loj uas tsim los ntawm Changfei Company, uas muaj cov coefficient attenuation qis dua thiab thaj chaw ua haujlwm loj dua, pab kom paub txog qhov system spectral dav dav nthuav dav mus rau S-band, thiab qhov siab tshaj plaws ntawm lub sijhawm tiag tiag ib nthwv dej ncav cuag 1.2Tbit / s. Lubcov khoom siv fiber ntautau pom qhov chaw ntawm kev tsim qauv, kev npaj, txheej txheem, cov ntaub ntawv raw thiab lwm yam kev sib txuas.
Kev siv tshuab txawj ntse thiab nws cov ntawv thov lag luam tab tom nce siab, ua rau muaj kev xav tau bandwidth sib txuas ntawm cov chaw khaws ntaub ntawv. Raws li lub hauv paus bandwidth ntawm cov ntaub ntawv digital, all-optical network yuav tsum tau ua kom dhau qhov nrawm thiab muaj peev xwm ntawm kev xa xov optical. Ua raws li lub hom phiaj ntawm "kev sib txuas ntse rau lub neej zoo dua", lub tuam txhab yuav koom tes nrog cov neeg ua haujlwm thiab cov neeg siv khoom los tsom mus rau kev tshawb fawb thiab kev txhim kho cov thev naus laus zis tseem ceeb ntawm kev sib txuas lus optical, ua kev koom tes tob tob thiab kev tshawb nrhiav kev lag luam hauv cov teb ntawm cov nqi tshiab, cov bands tshiab, thiab cov fibers optical tshiab, thiab tsim cov khoom lag luam zoo tshiab nrog kev tsim kho tshiab, txhawb nqa kev txhim kho tas li ntawm all-optical network, thiab pab tsim lub hauv paus ruaj khov rau yav tom ntej digital.
