Keywords: optical network muaj peev xwm nce, nruam technologies innovation, high-speed interface pilot tej yaam num maj launched
Nyob rau hauv lub era ntawm kev suav lub hwj chim, nrog lub zog tsav ntawm ntau yam tshiab cov kev pab cuam thiab kev siv, multi-dimensional muaj peev xwm txhim kho technologies xws li teeb liab tus nqi, muaj spectral dav, multiplexing hom, thiab tshiab kis tau tus mob media txuas ntxiv innovate thiab tsim.
Ua ntej ntawm tag nrho cov, los ntawm qhov kev xav ntawm lub interface los yog channel teeb liab tus nqi nce, lub teev ntawm10 G PONKev xa mus rau hauv lub network tau nthuav dav ntxiv, cov qauv txheej txheem ntawm 50G PON feem ntau ruaj khov, thiab kev sib tw rau 100G / 200G PON kev daws teeb meem yog qhov hnyav;Kev sib txuas lus network yog dominated los ntawm 100G / 200G ceev Expansion, qhov kev faib ua feem ntawm 400G cov ntaub ntawv chaw nyob rau hauv los yog sab nraud interconnection tus nqi yuav tsum tau nce ntau, thaum 800G / 1.2T / 1.6T thiab lwm yam ntau dua tus nqi khoom tsim thiab kev tshawb fawb txuj kev sib koom tes txhawb nqa. , thiab ntau txawv teb chaws optical kev sib txuas lus lub taub hau manufacturers yuav tsum tau tso tawm 1.2T los yog siab dua tus nqi coherent DSP processing nti khoom los yog pej xeem txoj kev npaj.
Thib ob, los ntawm qhov kev xav ntawm qhov muaj spectrum rau kev sib kis, maj mam nthuav dav ntawm kev lag luam C-band mus rau C + L band tau dhau los ua kev daws teeb meem hauv kev lag luam.Nws tau cia siab tias qhov kev sim kis tau zoo yuav txuas ntxiv txhim kho rau lub xyoo no, thiab tib lub sijhawm txuas ntxiv ua kev tshawb fawb txog kev dav dav xws li S + C + L band.
Thib peb, los ntawm qhov kev xav ntawm lub teeb liab multiplexing, qhov chaw faib multiplexing tshuab yuav raug siv los ua ib qho kev daws teeb meem mus sij hawm ntev rau lub bottleneck ntawm lub peev xwm kis tau tus mob.Lub submarine cable system raws li maj mam nce tus naj npawb ntawm optical fiber ntau yuav txuas mus ntxiv thiab nthuav dav.Raws li hom multiplexing thiab/los yog ntau yam Lub tshuab ntawm cov tub ntxhais multiplexing yuav txuas ntxiv mus kawm rau hauv qhov tob, tsom mus rau kev nce kev sib kis thiab txhim kho kev sib kis.
Tom qab ntawd, los ntawm qhov kev xav ntawm kev xa xov xwm tshiab, G.654E ultra-tsawg-tsawg optical fiber ntau yuav dhau los ua thawj qhov kev xaiv rau lub cev network thiab ntxiv dag zog rau kev xa tawm, thiab nws yuav txuas ntxiv mus kawm rau qhov chaw sib faib multiplexing optical fiber (cable).Spectrum, qeeb qeeb, tsis tshua muaj cov nyhuv nonlinear, tsis tshua muaj dispersion, thiab lwm yam ntau yam zoo tau dhau los ua qhov tseem ceeb ntawm kev lag luam, thaum kis tau tus mob tsis zoo thiab cov txheej txheem kos duab tau ua kom zoo dua ntxiv.Tsis tas li ntawd, los ntawm qhov kev xav ntawm cov cuab yeej technology thiab cov khoom lag luam kom paub tseeb, kev tsim kho kev lag luam, thiab lwm yam, cov neeg ua haujlwm hauv tsev yuav tsum tau tsim cov kev sib txuas ntawm kev kub ceev xws li DP-QPSK 400G kev ua haujlwm ntev, 50G PON dual-mode coexistence. thiab symmetrical kis tau tus mob muaj peev xwm nyob rau hauv 2023 Qhov kev kuaj xyuas ua hauj lwm ntxiv txheeb xyuas qhov kev loj hlob ntawm ib txwm high-speed interface khoom thiab lays lub hauv paus rau kev lag luam xa mus.
Thaum kawg, nrog kev txhim kho ntawm cov ntaub ntawv sib cuam tshuam thiab hloov peev xwm, kev sib koom ua ke ntau dua thiab kev siv hluav taws xob qis dua tau dhau los ua qhov kev xav tau ntawm kev kho qhov muag module ntawm qhov yooj yim chav tsev ntawm kev sib txuas lus kho qhov muag, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv chaw thov scenarios, thaum lub peev xwm hloov mus txog 51.2. Tbit / s Thiab saum toj no, kev sib xyaw ua ke ntawm optical modules nrog tus nqi ntawm 800Gbit / s thiab saum toj no tuaj yeem ntsib kev sib tw sib tw ntawm pluggable thiab photoelectric pob (CPO).Nws cia siab tias cov tuam txhab xws li Intel, Broadcom, thiab Ranovus yuav txuas ntxiv hloov tshiab nyob rau hauv lub xyoo no Ntxiv nrog rau cov khoom lag luam CPO thiab cov kev daws teeb meem uas twb muaj lawm, thiab tej zaum yuav nthuav tawm cov qauv khoom tshiab, lwm cov tuam txhab thev naus laus zis silicon photonics tseem yuav ua raws li kev tshawb fawb thiab kev loj hlob. los yog ua tib zoo mloog nws.
Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm photonic integration technology raws li optical module daim ntaub ntawv, silicon photonics yuav coexist nrog III-V semiconductor integration technology, muab hais tias silicon photonics technology muaj kev koom ua ke siab, kev kub ceev, thiab zoo compatibility nrog uas twb muaj lawm CMOS txheej txheem Silicon photonics tau. maj mam siv nyob rau hauv nruab nrab thiab luv luv-ntu pluggable optical modules, thiab tau dhau los ua thawj qhov kev tshawb nrhiav kev daws teeb meem rau CPO kev koom ua ke.Kev lag luam yog qhov zoo txog kev txhim kho yav tom ntej ntawm silicon photonics thev naus laus zis, thiab nws cov ntawv thov kev tshawb nrhiav hauv kev suav kho qhov muag thiab lwm qhov chaw kuj tseem yuav ua kom tiav.
