Kuvakwa kwe5G kuchafambisa kukurumidza kukura kwekudiwa kwe optical modules ye telecommunications.Nezve 5G optical module zvinodiwa, yakakamurwa kuva zvikamu zvitatu: fronthaul, midhaul, uye backhaul.
5G pamberi: 25G / 100G optical module
5G network inoda yakakwirira base station/sero saiti density, saka kudiwa kweakakwira-kumhanya optical modules kwawedzera zvakanyanya.25G/100G optical modules ndiyo inosarudzwa mhinduro ye5G fronthaul network.Sezvo eCPRI (yakagadziridzwa yakajairika yeruzhinji radio interface) protocol interface (yakajairika mwero ndeye 25.16Gb / s) inoshandiswa kutumira mabhendi ebhendi e5G base station, iyo 5G fronthaul network ichavimba zvakanyanya ne25G optical modules.Vashandi vari kushanda nesimba kugadzirira zvivakwa uye masisitimu ekufambisa shanduko kuenda ku5G.Pamusoro payo, muna 2021, iyo yepamba 5G inodiwa optical module musika inotarisirwa kusvika RMB 6.9 bhiriyoni, ine 25G optical modules inoverengera 76.2%.
Tichifunga nezve yakakwana yekunze application nharaunda ye5G AAU, iyo 25G optical module inoshandiswa mu fronthaul network inoda kusangana neindasitiri tembiricha ye -40 ° C kusvika + 85 ° C uye inodzivirira guruva zvinodiwa, uye 25G grey mwenje uye ruvara mwenje. ma modules anozoendesa zvinoenderana neakasiyana fronthaul architecture anoshandiswa mu5G network.
Iyo 25G grey optical module ine akawanda optical fiber zviwanikwa, saka inonyanya kukodzera kune optical fiber point-to-point optical fiber yakananga kubatana.Kunyangwe iyo optical fiber yakananga yekubatanidza nzira iri nyore uye yakaderera mumutengo, haigone kusangana nemabasa ekutonga akadai sekuchengetedza network uye kutarisa.Naizvozvo, haigone kupa kuvimbika kwakanyanya kweRLLC masevhisi uye inoshandisa yakawanda optical fiber zviwanikwa.
25G color optical modules inonyanya kuisirwa mupassive WDM uye inoshanda WDM / OTN network, nekuti inogona kupa akawanda AAU kune DU kubatana uchishandisa imwe fiber.Iyo passive WDM solution inopedza zvishoma fiber zviwanikwa, uye passive midziyo iri nyore kuchengetedza, asi haigone kuwana network yekutarisa, kudzivirira, manejimendi uye mamwe mabasa;inoshanda WDM/OTN inochengetedza zviwanikwa zvefiber uye inogona kuita OAM mabasa akadai sekuita pamusoro uye kuona kukanganisa, uye Ipa network kuchengetedza.Iyi tekinoroji ine maitiro eiyo bandwidth hombe uye yakaderera kunonoka, asi chakashata ndechekuti mutengo wekuvaka network wakakwira.
100G optical modules inoonekwawo seimwe yezvisarudzo zvinosarudzwa zve fronthaul network.Muna 2019, 100G uye 25G optical modules akaiswa seyakajairwa kuisirwa kuti aenderane nekukurumidza kusimudzira kwe5G yekushambadzira uye masevhisi.Mu fronthaul network inoda kukurumidza kukurumidza, 100G PAM4 FR / LR optical modules inogona kushandiswa.Iyo 100G PAM4 FR/LR optical module inogona kutsigira 2km (FR) kana 20km (LR).
5G kutumira: 50G PAM4 optical module
Iyo 5G mid-transmission network ine zvinodiwa zve50Gbit/s optical modules, uye zvese zviri zviviri grey uye color optical modules zvinogona kushandiswa.Iyo 50G PAM4 QSFP28 optical module inoshandisa LC optical port uye single-mode fiber inogona kaviri bandwidth kuburikidza ne single-mode fiber link pasina kuisa sefa yewavelength division multiplexing.Kuburikidza neDCM yakagovaniswa uye BBU saiti kukwidziridzwa, 40km inogona kutapurirana.Iko kudiwa kwe50G optical modules kunyanya kunobva mukuvakwa kwe5G bearer network.Kana 5G mutakuri network akagamuchirwa zvakanyanya, musika wayo unotarisirwa kusvika makumi emamiriyoni.
5G backhaul: 100G/200G/400G optical module
Iyo 5G backhaul network inozoda kutakura traffic yakawanda kupfuura 4G nekuda kwekuita kwepamusoro uye yakakwirira bandwidth 5G NR redhiyo itsva.Nokudaro, iyo convergence layer uye core layer ye 5G backhaul network ine zvinodiwa zveDWDM color optical modules nekumhanya kwe100Gb / s, 200Gb / s, uye 400Gb / s.Iyo 100G PAM4 DWDM optical module inonyanya kuiswa mumuganhu wekuwana uye convergence layer, uye inogona kutsigira 60km kuburikidza neT-DCM yakagoverwa uye optical amplifier.Iyo core layer transmission inoda huwandu hwepamusoro uye kureba kwe80km, saka 100G/200G/400G inobatana DWDM optical modules inodiwa kutsigira metro core DWDM network.Ikozvino, chinhu chinonyanya kukurumidza kudiwa kwe5G network ye100G optical modules.Vanopa masevhisi vanoda 200G uye 400G bandwidth kuti vagone kuwana iyo throughput inodiwa pakutumirwa kwe5G.
Pakati pe-transmission uye backhaul scenarios, optical modules inowanzoshandiswa mumakamuri emakombiyuta ane mamiriro ari nani ekupisa kupisa, saka mabhizimisi-grade optical modules anogona kushandiswa.Parizvino, nzvimbo yekufambisa iri pasi pe80km inonyanya kushandisa 25Gb / s NRZ kana 50Gb / s, 100 Gb / s, 200Gb / s, 400Gb / s PAM4 optical modules, uye kuendesa kure-kure pamusoro pe80km kuchanyanya kushandisa coherent optical modules. mutakuri mumwe chete 100 Gb/s uye 400Gb/s).
Muchidimbu, 5G yakakurudzira kukura kwe25G/50G/100G/200G/400G optical module musika.
