Muaj peb qhov kev sib tw sim rau 5G / data center optical module:
1. Cov ntaub ntawv siab dua ntawm qib hluav taws xob kho qhov muag tau los ntawm 10g txog 25G, kev hloov pauv ntawm optical module hluav taws xob nti. Qhov nce ntawm cov teeb liab loj siab, tshwj xeeb tshaj yog rau kev nyob deb, xav kom nce CDR nti ua. Txhawm rau nrog lub teeb liab jitter, teeb liab attenuation, jitter zam kev ntsuas, siab qhov muag kuaj tau ua tiav thaum txais qhov kawg, thiab txais tos sib luag tau qhia rau 25G optical module.
2. Tshiab hom kev hloov kho hom, ntau qhov nyuaj yuav tsum tau kuaj.
3. Tshuav nyiaj txiag ntawm cov khoom siv fiber ntau, nrug, kev ua tau zoo thiab tus nqi: ntau yam ntawm cov khoom siv ntau dua hauv 5G network. Xws li siv cov khoom siv kho qhov muag fiber ntau daim kab xev, PON, txhawm rau kom txuag tau kom ntau li ntau tau ntawm lub hauv ntej kis fiber ntau, kev siv cov khoom siv wavelength faib tshuab.
Kev siv WDM thev naus laus zis thov 5G kho qhov muag tuaj yeem faib ua coarse wavelength division multiplexing, nruab nrab wavelength faib multiplexing, zoo wavelength faib multiplexing thiab ntom ntuag faib faib ntau yam.
Muaj rau lub yoj yoj hauv qhov sib faib ntawm cov yoj yoj yoj sib faib, thiab tus naj npawb ntawm wavelengths nyob hauv nruab nrab wavelength faib thiab ntom ntom ntom ntab yuav sib npaug. Qhov siab tshaj plaws wavelength ntawm DWDM yog 40, thiab qhov txawv ntawm ib ntu yog los ntawm 20nm txog 0.4nm.
Daim ntawv thov ntawm WDM hauv 5G cov nqa khoom network xav tau sim CWDM / DWDM hauv qhov kho qhov muag. Muaj ob txoj hauv kev. Thawj yog yoj tes tsom kab hluav taws xob, uas yuav siv cov teeb pom kev dav dav thiab lub teeb tsom, thiab lwm txoj kev yuav siv cov laser kho tau qhov chaw thiab cov tsom iav micro tsom iav los yog ua ke nrog polarization synthesizer los kuaj. Qhov sib txawv ntawm ob txoj kev yog tias lub tshuab ntsuas hluav taws xob npog ntau yam ntawm cov yoj yoj. Tab sis qhov kev qhia tsis meej yog pom tseeb, qhov kev xeem nrawm qeeb, qhov ua tau zoo yog tsis siab, thiab kev xeem tiav tsis txaus. Yog li ntau ntawm lawv yuav siv adjustable laser qhov chaw thiab cov kho qhov muag tsom iav tsom iav kuaj cov khoom kuaj.
