Txhawm rau ua kom tau raws li qhov xav tau ntawm 5G nqa lub teeb module ntawm tus nqi qis, txhawb kev txhim kho kev noj qab haus huv ntawm cov kev lag luam cuam tshuam thiab pom zoo lub teeb module, module manufacturers, cov neeg siv khoom kawg, cov khoom lag luam, cov koom haum tshawb fawb, xws li cov koom haum kev lag luam kom muaj zog ntawm qhov chaw ntawm kev lees paub. Qhov zoo ntawm lub teeb module, los ntawm qhov ntsuas kev ua kom zoo tshaj plaws, qhov ntsuas thiab cov peev txheej rov qab siv, cov khoom tseem ceeb los ntawm ntau yam los txhim kho:
(1) Txheeb xyuas qhov yuav tsum tau ua tiag tiag ntawm daim ntawv thov scenarios thiab kis tau tus mob nyob deb, thiab ua kom pom tseeb ntawm qhov ntsuas qhov ntsuas qhov ntsuas qhov xav tau. Ua ntej, qhov txuas pob nyiaj siv ntawm lub fronthaul module yog optimized, thiab xaiv qhov piv ntawm industrial-qib lasers tuaj yeem txhim kho los ntawm kev so kom zoo rau qhov ntsuas. Qhov thib ob, qee qhov kev thov, tshwj xeeb tshaj yog hauv cheeb tsam nroog, tuaj yeem so OSNR qhov ntsuas ntawm lub kaw lus ntawm lub teeb pom kev sib txuas (xws li 1 ~ 2dB) raws li qhov xav tau tiag tiag, tuaj yeem txhawb nqa kev lag luam ntau dua DSP chips, thiab txo cov nqi tsim tawm. los ntawm kev ua kom yooj yim rau DSP muaj nuj nqi thiab algorithm. Thib peb, qhov tso zis hluav taws xob xav tau ntawm silicon-based coherent optical modules yuav tsum tau so kom tsim nyog. Piv txwv li, yog tias cov zis hluav taws xob kho qhov muag tau so mus rau -15dbm qib, cov txiaj ntsig ntawm silicon optical chips yuav zoo dua.
(2) Lub tswv yim module yuav tsum tsom ntau npaum li qhov ua tau thiab siv tag nrho cov txheej txheem thev naus laus zis thiab kev lag luam. Ua ntej, lub teeb ci pem hauv ntej yog tsom ntawm 25Gb / s Duplex 300m,25 Gb/s BIDI10/15km, thiab lwm yam. Qhov thib ob, cov ntaub ntawv chaw thiab kev sib txuas lus yog siv nyob rau hauv nruab nrab thiab rov qab lub teeb kis tau tus mob module. Thib peb, 25Gb / s BIDI lub tswv yim tau txais kev paub tab BOSA ntim tshuab ntawm10 Gb/s BIDIntawm thawj theem.
(3) Txuas ntxiv txhim kho kev tshawb fawb tus kheej hauv tsev thiab kev tsim khoom loj ntawm cov tub ntxhais chips. Ua ntej, kev lag luam kub ntau ntawm laser nti los hloov cov lag luam qib laser nti; Thib ob, silicon optical integrated nti, nqaim kab dav adjustable laser chip technology breakthrough; Thib peb, DSP, laser tsav IC localization.
