Nrog rau kev xa mus nrawm nrawm ntawm lub ntiaj teb broadband internet satellite constellations thiab qhov loj -scale rollout ntawm Fiber- mus rau -the-Home (FTTH) tes hauj lwm, SAT-IF Optical Receiver (Satellite-Intermediate Frequency Optical Receiver}), raws li ib tug tub ntxhais ntawm fiber ntau transmissions, ntsib kev lag luam uas tsis tau pom dua. Lub ntiaj teb satellite chaw nres tsheb cov khoom lag luam ua lag luam tau txog $ 12.71 nphom hauv 2024, thiab SAT-IF optical receiver, nrog nws qhov siab -kev ua tau zoo photoelectric hloov dua siab tshiab muaj peev xwm thiab kev tsim qauv tsim, tau dhau los ua qhov tseem ceeb thev naus laus zis ntawm kev sib sib zog nqus ntawm kev sib txuas lus satellite thiab fiber optic networks.
Technological Breakthrough: Tsiv los ntawm Kev Tsim Kho Vaj Tse mus rau Ncaj Ncees -Kev Hloov Kho Kev daws teeb meem
Ntawm qhov kev hloov pauv ntawm thev naus laus zis, tiam tshiab ntawm SAT-IF optical receivers tau ua tiav ib qho kev dhia los ntawm ib txwm superheterodyne architectures coj mus rau - hloov dua siab tshiab architectures. Thaum cov neeg txais ib txwm siv txoj hauv kev ua haujlwm hierarchical ntawm RF filtering, qis - suab nrov amplification, thiab kev sib xyaw hloov pauv, SAT tshiab-IF optical receivers ncaj qha siv optical I/Q nrhiav kom tau siv ob khub ntawm cov receivers sib npaug thiab optical 90-degree hybrid, txhim kho cov teeb liab kev ua tau zoo thiab zoo.
Piv txwv li, FTTH- mob siab rau SAT-IF optical receiver launched los ntawmZoo siab Electronics (Shenzhen) Co., Ltd.txhawb nqa ntau qhov kev khiav hauj lwm zaus: 45-1000MHz, 45-2150MHz, thiab 45-2400MHz, ua tau raws li triple-ua si yuav tsum tau sib kis ntawm cov ntaub ntawv, lub suab, thiab cov teeb liab video. Tsis tas li ntawd, peb satellite L-band PIN optical receiver siv lub siab-rhiab heev PIN ntes nrog qhov tau txais kev nkag siab ntawm -22dBm (tus nqi raug -13dBm), kev khiav hauj lwm zaus npog 950 ~ 2600MHz, muaj peev xwm tau txais tag nrho L-band analog thiab digital signals los ntawm LNB satellite antennas.
Nyob rau hauv cov nqe lus ntawm kev ua haujlwm tseem ceeb, SAT cov ntsiab lus tseem ceeb-IF optical receivers tau ua tiav kev lag luam- theem ua: CNR Ntau dua lossis sib npaug rau 50dB, CSO Ntau dua lossis sib npaug rau 65dB, CTB Ntau dua lossis sib npaug rau 62dB, kom ntseeg tau siab {{5}fidelity signal transmission} ntev dua. Lub caij no, daim ntawv thov ntawm GaAs amplifier nquag siv thiab ultra-tsawg- suab nrov thev naus laus zis txo cov suab nrov thaum lub sijhawm ua cov teeb liab, txhim kho cov teeb liab purity.
Kev nthuav dav: Los ntawm Chaw Nyob FTTH mus rau Maritime Communications thiab Satellite Ground Stations
Daim ntawv thov scenarios ntawm SAT-IF optical txais tau nthuav dav sai. Hauv FTTH tes hauj lwm, lub cuab yeej hloov pauv tag nrho L-band analog satellite teeb liab tau txais los ntawm satellite kav hlau txais xov LNB rau hauv cov teeb liab kho qhov muag, ua rau siab -pob tshab, siab- zoo ntev- kis tau tus mob hla fiber ntau optics. Cov khoom siv kho qhov muag tau tso tawm los ntawm BAUDCOM siv siab -bandwidth, siab-rhiab heev photodiodes thiab qis- suab nrov sib cuam tshuam circuits, nrog kev txais kev kho qhov muag ntau ntawm -15 ~ +2dBm, thiab hluav taws xob AGC uas ua tiav qhov kev tso tawm RF ntawm 800V. -8 ~ 0dBm. Nws yog tsim tshwj xeeb rau triple - ua si tes hauj lwm uas sib koom xa CATV thiab SAT-IF cov cim.
Hauv cov khoom siv hauv av satellite hauv av, SAT-IF optical receiver plays lub luag haujlwm tseem ceeb raws li cov khoom siv tseem ceeb hauv kev xa tawm los ntawm satellites mus rau hauv av chaw nres tsheb. Hangzhou Huatai cov khoom lag luam muaj ntau yam qauv xws li 1U 19-inch standard rack-mount, desktop, wall-mount, thiab waterproof type, adapting to different fiber access scenarios such as FTTH, FTTP, FTTB, thiab FTTC. Nws kuj tseem ua ke nrog WD1543 wavelength splitter kom muaj kev sib txuas nrog ONUs hauv EPON thiab GPON systems.
Tsis tas li ntawd, cov cuab yeej tau siv dav hauv cov chaw taws teeb marine satellite L-band fiber ntau faib tshuab thiab satellite L-band uplink/downlink fiber optic txuas, muab cov nqi qis thiab txhim khu kev qha rau kev sib txuas lus hauv hiav txwv.
Kev Lag Luam Trends: Dual Tsav Tsheb los ntawm Triple Play thiab Optical SATCOM Terminal Markets
Los ntawm qhov kev xav ntawm kev lag luam macro, qhov txuas ntxiv tob zuj zus ntawm kev ua si triple yog tsim qhov chaw loj ntxiv rau SAT-IF optical receivers. Kev tsim kho ntawm FTTH fiber ntau-rau-- cov kev sib txuas hauv tsev ua rau CATV, satellite TV, thiab kev pabcuam hauv internet broadband xa mus rau hauv tsev neeg los ntawm ib qho khoom siv fiber ntau, nrog rauSAT-IF optical receiverua lub luag haujlwm tseem ceeb ntawm kev hloov kho qhov muag teeb liab rov qab rau RF cov cim. Polytron's LOS YOG 9 QT optical receiver converts tau txais cov teeb liab kho qhov muag rau hauv RF signals, outputting rau yim tsau SAT polarization theem outputs thiab ib tug terrestrial tso zis rau txuas multi- hloov khoom siv, muab ib tug ua tiav kev daws teeb meem rau multi- neeg siv faib tshuab.
Nyob rau tib lub sijhawm, lub ntiaj teb kho qhov muag SATCOM davhlau ya nyob twg kev lag luam tab tom muaj kev loj hlob sai. Kev nthuav dav txuas ntxiv ntawm Low Earth Orbit (LEO) thiab Medium Earth Orbit (MEO) satellite constellations yog tsav qhov kev thov nce rau kev cog lus, ua tau zoo, thiab txhim khu kev qha optical terminals. Thaum Lub Peb Hlis 2026, MACOM tau nthuav tawm nws cov kev sib xyaw ua ke microwave thiab kho qhov muag ntawm SATShow Lub Limtiam 2026, suav nrog ntau yam khoom txhawb nqa Free Space Optics (FSO) thiab Xov Tooj Cua- dhau-Fiber (RFoF), nrog rau cov khoom siv kho qhov muag SATCOM kis tau tus mob rau hauv av-mus rau{{7}8} hauv av, satellite-rau-satellite txuas, ntxiv kev lees paub qhov tseem ceeb ntawm kev siv tshuab optical kev sib txuas lus hauv kev sib txuas lus satellite.
Tsis tas li ntawd nyob rau lub Peb Hlis 2026, NEC Corporation tshaj tawm ua tiav ntawm kev tsim thev naus laus zis ua qauv qhia satellite khoom siv rau Nyij Pooj thawj qhov kev sib txuas lus kho qhov muag satellite constellation, uas yuav ua hauv - kev txheeb xyuas lub voj voog npog cov thev naus laus zis tseem ceeb xws li kev sib txuas lus kho qhov muag thiab siab - kev sib txuas ceev ceev. Qhov kev kawm no qhia tau hais tias kev sib txuas lus kho qhov muag tau txuas ntxiv los ntawm kev siv FTTH hauv av mus rau ntu ntu.
Yav Tom Ntej Outlook: Synergistic Development of Terrestrial and Space Optical Communications
Nrog rau kev xa tawm loj ntawm Starlink txuas ntxiv, lub sijhawm xa tawm sai ntawm Tuam Tshoj lub hnub qub Guowang tom qab 2026, thiab Amazon's Kuiper pib nws thawj satellite xa mus rau xyoo 2025, lub ntiaj teb LEO satellite constellation kev tsim kho tau nkag mus rau dawb- theem kub. Qhov kev xav no yuav ua rau muaj kev xav tau ntau dua hauv av- ntu cov khoom siv kho qhov muag tau txais- tau txais kev nkag siab ntau dua, kev ua haujlwm dav dav dua, thiab kev hloov pauv ib puag ncig muaj zog yuav dhau los ua cov lus qhia tseem ceeb rau kev hloov pauv tom ntej - tiamSAT-IF optical receivers.
Nyob rau theem technological roadmap, kev sib koom ua ke ntawm terrestrial SAT-IF optical receivers thiab space optical communication terminals yog accelerating. Cov cuab yeej siv hauv av yuav tsum tau sib haum nrog ntau zaus bands, txhawb nqa cov teeb liab ua haujlwm nyuaj dua, thiab ua tau raws li qhov yuav tsum tau ua - txo nqi kom haum rau loj - kev lag luam xa tawm. Los ntawm dej hiav txwv- mus rau cov nkoj mus rau thaj chaw deb thaj tsam broadband nkag, los ntawm thaj chaw FTTH mus rau loj- nplai satellite hauv av chaw nres tsheb, SAT-IF optical receiver, nrog nws cov khoom sib txawv thiab cov kev ntsuas kev ua tau zoo txuas ntxiv, yog pab txhawb kev loj hlob thoob ntiaj teb rau kev sib txuas lus satellite.
