Lub ntiaj teb digital coherent optics Transceolic kev ua lag luam Transceased los ntawm 2024 rau USD 0.26) Cov kev sim tsis ntev los no: Nokia thiab ote pab pawg tau kis dua 8,2Gbps tshaj li 9,290 km thiab 900gbps tshaj li 1,290 17}} Coherent Technology (Source Coherent Technology (Source: Nokia.com, 2024). Cov thev naus laus zis hloov peev xwm ua kom muaj kev nthuav dav ntau dua, cov paib txuas ntxiv piv rau txoj kev ncaj qha rau kev kuaj pom kev cai.

Kev siv kho qhov muag siv tau siv cov tshuab nrog kev pom kev ncaj qha, cov ntaub ntawv encoding tsuas yog hauv kev siv lub teeb hloov. Qhov kev cuam tshuam no txwv ob lub peev xwm thiab kev deb. Coherent optics Exploits Tag nrho cov khoom ntawm lub teeb vuag los ua kom tiav cov ntaub ntawv dhau los.

Cov lus dag ua kom muaj kev pom. Lub zos oscillator laser mixes nrog cov teeb liab tau txais hauv cov txheej txheem sib koom ua ke thaum them nyiaj tawm hauv cov txheej txheem sib cais thiab cov polrompersion (qhov chaw: accton.com, 2022). Qhov no pab tau kev sib kis ntawm cov terhabits ntau txhiab mais kev siv ib khub khub fiber ntau.

Thaum kuaj pom kev ncaj qha tsuas yog siv tau, sib kis txoj kev tsheb ciav hlau:

THEEM kev hloov kho: Cov ntaub ntawv tshaj tawm rau hauv kev pom tias lub teeb yoj yoj yoj los ntawm theem hloov chaw. Quadrinutate theem hloov chaw tso cai tso cai ntau cov cim ib me ntsis uas siv plaub ntu kev paub (0 degree, 90 degree, 270 degree). Dual Polarization Qpsk Twubles Muaj Peev Xwm Los ntawm kev siv cov kab rov tav thiab ntsug polarization ib txhij.

Qhov kev tawm tsam loj heev: Quadrutify amplitude modulation ua ke theem thiab cov ntaub ntawv amplitude. Kev tshawb fawb qhia pom tias ib tug residual cov qauv ua haujlwm tau txhim kho bitrate thiab spectrated tawm tswv yim lasers nrog 3 MHz Linewidth (Source: XwmCom.com, 2024).

Kev Ua Si Polarization Multiplexing: Los ntawm kev hloov cov ntaub ntawv sib txawv ntws ntawm Orthoogonal X thiab Y Polarizations, cov qauv zoo ob chav muaj peev xwm yuav tsum tau ntxiv rau spectrum ntxiv.

Niaj hnub kev sib koom kho cov tshuab niaj hnub xa tuaj yeem ua cov chips uas tau ua ntau lub luag haujlwm tseem ceeb. Cov txheej txheem no coj txoj kev sib txuas lus tsis zoo, them nyiaj rau kev hloov kho cov ntsiab lus muaj hmoo, thiab tuaj yeem hloov kho cov cim hluav taws xob, rov qab rau cov cim kev ncaj ncees tshaj qhov txuas ntxiv mus.

Lub DSP muab cov nyiaj them poob haujlwm chromatic dispersion, tshem tawm cov zaus - ywj pheej theem uas degrade teeb tsa hauv cov txheej txheem ib txwm muaj. Txog polarization hom dispersion, cov txheej txheem txuas ntxiv mus thiab kho qhov kev ncua siab ntawm polarization hais. Tiag tiag - lub sij hawm adaptive sib luag rau cov txheej txheem dynamic channel.

Siab dua - Kev txiav txim siab hloov kho cov lus qhia ntxiv rau hauv txhua lub tsheb sib kis. Thaum pib cov tshuab siv ntxov siv QPSK (4 xeev), niaj hnub ua kev siv qib siab:

Qhov probarilitic constellation shauing ua hauj lwm muaj peev xwm mus cuag lub shannon txwv los ntawm kev ua kom zoo tshaj plaws cov cim raws li channel mob (chaw: rd.ntt, 2024).

Tsis zoo li cov kev ntsuas tshwj xeeb uas tsuas yog siv tau, coerent cov neeg tau txais teeb liab nrog lub zos oscillator laser. Qhov no heterodyne lossis homernnene tab tom pom zoo rau cov lus qhia txog kev kub ntxhov thiab theem cov ntaub ntawv nrog cov suab nrov tshwj xeeb, txawm tias muaj suab nrov.

Cov txheej txheem siv 90 {-℃hybrid uas cais nyob rau hauv-theem thiab cov plaub fab sib cais hauv ob x thiab y pol polarizations. Plaub lub photodetectors hloov cov teeb meem kho tshiab rau hluav taws xob, uas DSP cov txheej txheem los rho cov ntaub ntawv kis.

Kev Sib Kis: Coherent system tau hloov cov txhiab mais tsis muaj dua tshiab. Kev nrhiav ncaj qha feem ntau txwv rau 10-40 km ua ntej teeb meem degradation ua teeb meem. Cov kev txhim kho tau zoo nyob hauv Coherent System muab 3-5 DB kom zoo dua.

Spectral efficiency: Coherent Optics Ua tiav 2 {{- 4x siab dua spectral efficiency los ntawm multi} qib kev tawm tswv yim tawm tswv yim. Kev nrhiav ncaj qha tseem muaj kev txwv los ntawm kev tawm tsam-tsuas yog kev hloov kho, tsis muaj kev cuam tshuam ntau tshaj plaws.

Thaum Coherent Systems txo cov hwj chim network, DSP chips lawv tus kheej siv lub zog tseem ceeb. Kev siv tam sim no yuav tsum tau 8 {{{{-} 15w ib transceiver, piv rau 3 {5W rau kev kuaj kom pom kev. Txawm li cas los xij, nrog txhua lub cim tshiab ntawm kev sib koom ua kom zoo nkauj, lub zog uas yuav tsum tau ua rau muaj kev hloov pauv ntawm silicate

Nyob rau theem siab muaj zog, coerent cov cim tau raug rau cov fiber ntau dua li, thiab plaub} {yoj sib xyaw. Cov phenomena distort cov cim qhia thiab txwv tsis pub tshaj qhov kis tau lub zog. Advanced DSP algorithms txiav qee qhov cuam tshuam, tab sis cov tswv yim txwv constrain Fais fab theem rau 0-5 DBM rau ib channel.

Rau kev sib txuas nyob rau hauv 10 km, coherent optics feem ntau tsis tuaj yeem ua pov thawj tus nqi them ncaj qha hla cov kev pom kev ncaj qha. Lub rooj sib tham vim yog xav tau ntawm cov ntawv thov uas xav tau thiab tshwj xeeb, feem ntau tshwm sim ntawm 40-80 km nrug deb.
