Ukwakhiwa kwe-5G kuya kuqhuba ukukhula okukhawulezayo kwemfuno yeemodyuli ze-optical for telecommunications.Ngokwemiqathango ye-5G yeemfuno zemodyuli ye-optical, ihlulwe ibe ngamacandelo amathathu: i-fronthaul, i-midhaul, kunye ne-backhaul.
I-5G yangaphambili: i-25G / 100G imodyuli ye-optical
Amanethiwekhi e-5G afuna isikhululo esiphezulu sesikhululo / indawo ye-cell density, ngoko ke imfuno yeemodyuli ze-high-speed optical ziye zanda kakhulu.I-25G / 100G iimodyuli ze-optical ziyisisombululo esikhethiweyo se-5G inethiwekhi ye-fronthaul.Ekubeni i-eCPRI (i-interface ephuculweyo yerediyo yoluntu ephuculweyo) i-interface yeprotocol (izinga eliqhelekileyo yi-25.16Gb / s) isetyenziselwa ukuhambisa izibonakaliso ze-baseband zezikhululo zesiseko se-5G, inethiwekhi ye-fronthaul ye-5G iya kuxhomekeka kakhulu kwiimodyuli ze-25G optical.Abaqhubi basebenza nzima ukulungiselela iziseko zophuhliso kunye neenkqubo zokuququzelela utshintsho kwi-5G.Kwincopho yayo, ngo-2021, imarike yemodyuli ye-5G yasekhaya efunekayo kulindeleke ukuba ifikelele kwi-RMB 6.9 yeebhiliyoni, kunye neemodyuli ze-25G ze-optical account kwi-76.2%.
Ukuqwalasela indawo epheleleyo yesicelo sangaphandle ye-5G AAU, imodyuli ye-25G ye-optical esetyenziswe kwinethiwekhi ye-fronthaul idinga ukuhlangabezana nomgangatho wokushisa we-industrial -40 ° C ukuya ku-85 ° C kunye neemfuno zothuli, kunye ne-25G ukukhanya kwegrey kunye nokukhanya kombala. iimodyuli ziya kuSebenzisa ngokweendlela ezahlukeneyo zoyilo lwangaphambili olusetyenziswa kwiinethiwekhi ze-5G.
Imodyuli ye-25G ye-gray optical inezinto ezininzi ze-fiber optical, ngoko ke ifaneleka ngakumbi kwi-fiber optical point-to-point optical optical connection ngqo.Nangona indlela yokudibanisa ngqo i-fiber optical ilula kwaye iphantsi kweendleko, ayikwazi ukuhlangabezana nemisebenzi yolawulo efana nokukhuselwa kwenethiwekhi kunye nokubeka iliso.Ke ngoko, ayinakubonelela ngokuthembeka okuphezulu kwiinkonzo ze-urLLC kwaye isebenzise izibonelelo zefiber ebonakalayo.
Iimodyuli ze-25G zemibala ye-optical zifakwe ngokukodwa kwi-WDM engabonakaliyo kunye neenethiwekhi ezisebenzayo ze-WDM / OTN, kuba zinokubonelela nge-AAU ezininzi kwi-DU ukudibanisa usebenzisa i-fiber eyodwa.Isisombululo se-WDM esingenasiphelo sisebenzisa izixhobo ezincinci zefiber, kunye nezixhobo ze-passive kulula ukuzigcina, kodwa azikwazi ukufezekisa ukubeka iliso kwinethiwekhi, ukukhuselwa, ulawulo kunye neminye imisebenzi;I-WDM/OTN esebenzayo igcina izibonelelo zefiber kwaye inokufezekisa imisebenzi ye-OAM efana nentsebenzo engaphezulu kunye nokufumanisa impazamo, kunye nokubonelela ngokhuseleko lwenethiwekhi.Le teknoloji ngokwemvelo ineempawu ze-bandwidth enkulu kunye nokulibaziseka okuphantsi, kodwa ukungahambi kakuhle kukuba ixabiso lokwakhiwa kwenethiwekhi liphezulu kakhulu.
Iimodyuli ze-100G ze-optical nazo zibhekwa njengenye yezisombululo ezikhethiweyo kwiinethiwekhi ze-fronthaul.Kwi-2019, i-100G kunye ne-25G iimodyuli ze-optical zisekwe njengofakelo oluqhelekileyo ukugcina uphuhliso olukhawulezayo lwe-5G yorhwebo kunye neenkonzo.Kwiinethiwekhi ze-fronthaul ezifuna isantya esiphezulu, i-100G PAM4 FR / LR iimodyuli ze-optical zingasetyenziswa.I-100G PAM4 FR / LR imodyuli ye-optical inokuxhasa i-2km (FR) okanye i-20km (LR).
Ukuhanjiswa kwe-5G: I-50G PAM4 imodyuli ye-optical
Inethiwekhi ye-5G ye-middle-transmission ineemfuno ze-50Gbit / s iimodyuli ze-optical, kwaye zombini iimodyuli ezimpunga kunye nombala optical zingasetyenziswa.I-50G PAM4 QSFP28 imodyuli ye-optical usebenzisa i-LC optical port kunye ne-fiber-mode-modefiber inokuphinda kabini i-bandwidth ngokusebenzisa i-fiber-mode-mode link ngaphandle kokufaka i-filter ye-wavelength division multiplexing.Ngokusebenzisa i-DCM ekwabelwana ngayo kunye nokwandiswa kwendawo ye-BBU, i-40km inokudluliselwa.Imfuno yeemodyuli ze-50G ezibonakalayo zivela ikakhulu ekwakhiweni kweenethiwekhi ze-5G.Ukuba iinethiwekhi zabathwali be-5G zamkelwa ngokubanzi, imakethi yayo kulindeleke ukuba ifikelele kumashumi ezigidi.
I-5G i-backhaul: 100G / 200G / 400G imodyuli ye-optical
Inethiwekhi ye-backhaul ye-5G iya kufuna ukuthwala i-traffic eninzi kune-4G ngenxa yokusebenza okuphezulu kunye ne-bandwidth ephezulu ye-5G NR irediyo entsha.Ngako oko, i-convergence layer kunye ne-core layer ye-5G i-backhaul network ineemfuno ze-DWDM iimodyuli ze-optical color color ngesantya se-100Gb / s, i-200Gb / s, kunye ne-400Gb / s.I-100G PAM4 imodyuli ye-DWDM ye-optical isetyenziswa kakhulu kwinqanaba lokufikelela kunye ne-convergence layer, kwaye inokuxhasa i-60km nge-T-DCM ekwabelwana ngayo kunye ne-amplifier optical.I-core layer transmission idinga umthamo ophezulu kunye nomgama owandisiweyo we-80km, ngoko ke i-100G / 200G / 400G iimodyuli ze-DWDM ezibonakalayo ezihambelanayo ziyafuneka ukuxhasa i-metro core DWDM network.Ngoku, eyona nto ingxamisekileyo yimfuno yenethiwekhi ye-5G yeemodyuli ze-100G ezibonakalayo.Ababoneleli ngeenkonzo badinga i-200G kunye ne-400G i-bandwidth ukuze bafezekise i-throughput efunekayo kwi-5G yokuthunyelwa.
Kwiimeko zokudlulisa kunye ne-backhaul, iimodyuli ze-optical zivame ukusetyenziswa kumagumbi ekhompyutheni aneemeko ezingcono zokutshatyalaliswa kobushushu, ngoko ke iimodyuli ze-optical grade-grade zingasetyenziswa.Okwangoku, umgama wokuhambisa ngaphantsi kwe-80km ikakhulu usebenzisa i-25Gb / s NRZ okanye i-50Gb / s, i-100 Gb / s, i-200Gb / s, i-400Gb / s i-PAM4 iimodyuli ze-optical, kunye nokuhanjiswa kwexesha elide ngaphezu kwe-80km kuya kusebenzisa kakhulu imodyuli ye-optical ehambelanayo ( Umphathi omnye we-100 Gb / s kunye ne-400Gb / s).
Isishwankathelo, i-5G ikhuthaze ukukhula kwe-25G/50G/100G/200G/400G imodyuli ye-optical market.
