Ukwakhiwa kwe-5G kuzoqhuba ukukhula okusheshayo kwesidingo samamojula optical for telecommunications.Ngokwezidingo ze-5G optical module, ihlukaniswe yaba izingxenye ezintathu: i-fronthaul, i-midhaul, ne-backhaul.
I-5G fronthaul: 25G/100G module optical
Amanethiwekhi e-5G adinga isisekelo esiphezulu sesiteshi/ukuminyana kwesayithi lamaseli, ngakho isidingo samamojula okubona ngesivinini esiphezulu sikhule kakhulu.Amamojula we-25G/100G optical ayisixazululo esithandwayo samanethiwekhi we-5G fronthaul.Njengoba i-eCPRI (i-interface evamile yomsakazo womphakathi ethuthukisiwe) isikhombimsebenzisi sephrothokholi (isilinganiso esijwayelekile yi-25.16Gb / s) sisetshenziselwa ukudlulisa amasignali e-baseband eziteshi eziyisisekelo ze-5G, inethiwekhi ye-5G fronthaul izothembela kakhulu kumamojula we-25G optical.Abasebenzisi basebenza kanzima ukulungisa ingqalasizinda nezinhlelo ukuze kube lula ukushintshela ku-5G.Esiqongweni sayo, ngo-2021, imakethe yasekhaya ye-5G edingekayo ye-optical module kulindeleke ukuthi ifinyelele ku-RMB 6.9 billion, namamojula angama-25G afinyelela ku-76.2%.
Ngokucabangela indawo ephelele yesicelo sangaphandle ye-5G AAU, imojula ye-25G ye-optical esetshenziswa kunethiwekhi ye-fronthaul idinga ukuhlangabezana nezinga lokushisa lezimboni lika--40 ° C kuya ku-+85 ° C kanye nezidingo zokuvikela uthuli, kanye nokukhanya okumpunga okungu-25G nokukhanya kombala. amamojula azosebenza ngokuya ngezakhiwo ezihlukene ze-fronthaul ezisetshenziswa kumanethiwekhi e-5G.
I-25G grey optical module inezinsiza eziningi ze-fiber optical, ngakho ifaneleka kakhulu ukuxhumana okuqondile kwefiber optical point-to-point.Nakuba indlela yokuxhumana eqondile ye-fiber optical ilula futhi iphansi ngezindleko, ayikwazi ukuhlangabezana nemisebenzi yokuphatha efana nokuvikela inethiwekhi nokuqapha.Ngakho-ke, ayikwazi ukuhlinzeka ngokuthembeka okuphezulu kwezinsizakalo ze-urLLC futhi isebenzisa izinsiza ze-fiber optical ngaphezulu.
Amamojula okukhanya ombala we-25G afakwe ngokuyinhloko kumanethiwekhi e-WDM/OTN asebenzayo, ngoba angahlinzeka ngoxhumo oluningi lwe-AAU kuya ku-DU esebenzisa i-fiber eyodwa.Isixazululo se-WDM esingenzi lutho sisebenzisa izinsiza ezincane ze-fiber, futhi izinto ezisetshenziswayo kulula ukuzigcina, kodwa namanje azikwazi ukufeza ukuqapha kwenethiwekhi, ukuvikelwa, ukuphathwa kanye neminye imisebenzi;I-WDM/OTN esebenzayo yonga izinsiza zefiber futhi ingafinyelela imisebenzi ye-OAM efana nokusebenza phezulu nokutholwa kwamaphutha, kanye Nokuhlinzeka ngokuvikela kwenethiwekhi.Lobu buchwepheshe ngokwemvelo bunezici zomkhawulokudonsa omkhulu kanye nokulibaziseka okuphansi, kodwa okubi ukuthi izindleko zokwakha inethiwekhi ziphakeme kakhulu.
Amamojula we-100G optical nawo abhekwa njengenye yezixazululo ezithandwayo zamanethiwekhi angaphambili.Ngo-2019, amamojula we-100G kanye ne-25G optical asethwe njengokufakwa okujwayelekile ukuze ahambisane nokuthuthukiswa okusheshayo kwezentengiso nezinsizakalo ze-5G.Kumanethiwekhi e-fronthaul adinga isivinini esiphezulu, amamojula we-optical 100G PAM4 FR/LR angafakwa.I-100G PAM4 FR/LR module optical ingasekela i-2km (FR) noma i-20km (LR).
Ukudluliswa kwe-5G: I-50G PAM4 module optical
Inethiwekhi ye-5G ye-mid-transmission inezidingo zamamojula we-50Gbit/s optical, futhi womabili amamojula okukhanya okumpunga nawombala angasetshenziswa.I-50G PAM4 QSFP28 imojula ye-optical esebenzisa i-LC optical port kanye ne-fiber yemodi eyodwa ingakwazi kabili umkhawulokudonsa ngokusebenzisa isixhumanisi se-fiber yemodi eyodwa ngaphandle kokufaka isihlungi sokuphindaphinda kwe-wavelength division multiplexing.Ngokusebenzisa i-DCM eyabelwe kanye ne-BBU site amplification, i-40km ingadluliselwa.Isidingo samamojula we-50G optical ikakhulukazi sivela ekwakhiweni kwamanethiwekhi abathwali be-5G.Uma amanethiwekhi okuthwala i-5G emukelwa kabanzi, imakethe yawo kulindeleke ukuthi ifinyelele emashumini ezigidi.
I-5G backhaul: 100G/200G/400G module optical
Inethiwekhi ye-backhaul ye-5G izodinga ukuthwala ithrafikhi eningi kune-4G ngenxa yokusebenza okuphezulu kanye nomkhawulokudonsa ophezulu we-5G NR umsakazo omusha.Ngakho-ke, isendlalelo sokuhlangana kanye nesendlalelo esiyinhloko senethiwekhi ye-5G ye-backhaul inezidingo zamamojula okukhanya ombala we-DWDM anesivinini se-100Gb/s, 200Gb/s, kanye ne-400Gb/s.I-100G PAM4 DWDM optical module isetshenziswa ikakhulukazi kungqimba yokufinyelela kanye nesendlalelo sokuhlangana, futhi ingasekela i-60km nge-T-DCM eyabelwe kanye ne-optical amplifier.Ukudluliswa kwesendlalelo esiyinhloko kudinga umthamo ophezulu kanye nebanga elinwetshiwe lika-80km, ngakho-ke amamojula we-DWDM ahambisanayo we-100G/200G/400G ayadingeka ukusekela inethiwekhi ye-metro core DWDM.Manje, into ephuthuma kakhulu yisidingo senethiwekhi ye-5G samamojula we-100G optical.Abahlinzeki besevisi badinga i-200G kanye ne-400G yomkhawulokudonsa ukuze bafinyelele umphumela odingekayo ekusetshenzisweni kwe-5G.
Phakathi kwezimo zokudlulisela kanye ne-backhaul, amamojula optical avame ukusetshenziswa emakamelweni ekhompiyutha anezimo ezingcono zokushisa ukushisa, ngakho-ke amamojula optical-grade optical angasetshenziswa.Njengamanje, ibanga lokudlulisela elingaphansi kuka-80km lisebenzisa ikakhulukazi i-25Gb/s NRZ noma 50Gb/s, 100 Gb/s, 200Gb/s, 400Gb/s PAM4 amamojula optical, kanye nokudluliswa kwebanga elide ngaphezu kuka-80km kuzosebenzisa ikakhulukazi amamojula ahlangene optical ( inkampani yenethiwekhi eyodwa 100 Gb/s kanye 400Gb/s).
Kafushane, i-5G ikhuthaze ukukhula kwemakethe ye-optical module ye-25G/50G/100G/200G/400G.
