Keywords: optical network kugona kuwedzera, kuenderera mberi tekinoroji innovation, yakakwirira-kumhanya interface yekutyaira mapurojekiti zvishoma nezvishoma akatanga.
Munguva yesimba remakomputa, ine dhiraivha yakasimba yeakawanda masevhisi matsva uye maapplication, akawanda-dimensional masimba ekuvandudza matekinoroji akadai seyero yechiratidzo, inowanikwa spectral wide, multiplexing mode, uye mitsva yekufambisa midhiya inoenderera mberi nekuvandudza nekuvandudza.
Chekutanga pane zvese, kubva pakuona kweiyo interface kana chiteshi chiratidzo chekuwedzera, chiyero che10G PONkutumirwa mumambure ekuwana kwave kuchiwedzerwa, maitiro ehunyanzvi e50G PON anowanzo kugadzikana, uye kukwikwidza kwe100G/200G PON technical solutions kunotyisa; iyo network yekutumira inotongwa ne100G/200G kukurumidza Kuwedzera, chikamu che400G data center mukati kana kunze kwekubatanidza chiyero chinotarisirwa kuwedzera zvakanyanya, nepo 800G/1.2T/1.6T uye imwe yepamusoro chiyero chekugadzirwa kwechigadzirwa uye tekinoroji yekutsvagisa inokurudzirwa pamwe chete. , uye mamwe ekunze optical kutaurirana musoro vagadziri vanotarisirwa kuburitsa 1.2T kana yepamusoro mwero inobatana DSP kugadzirisa chip zvigadzirwa kana zvirongwa zvebudiriro yeruzhinji.
Kechipiri, kubva pamaonero eiyo inowanikwa spectrum yekutapurirana, kuwedzera zvishoma nezvishoma kweiyo yekutengesa C-bhendi kuenda kuC+L bhendi yave mhinduro yekubatanidza muindasitiri. Zvinotarisirwa kuti murabhoritari yekufambisa basa icharamba ichivandudza gore rino, uye panguva imwe chete ichienderera mberi nekuita tsvakiridzo pane yakafararira senge S + C + L bhendi.
Chechitatu, kubva pakuona kwechiratidzo chekuwedzera, tekinoroji yekuparadzanisa nzvimbo inozoshandiswa semhinduro yenguva refu kubhodhoro rekutakura simba. Iyo submarine tambo system yakavakirwa zvishoma nezvishoma kuwedzera huwandu hwe optical fiber pairs icharamba ichiiswa uye kuwedzera. Kubva pane mode multiplexing uye / kana akawanda Iyo tekinoroji yecore multiplexing icharamba ichidzidzwa zvakadzama, ichitarisa pakuwedzera kureba kwekutapurirana uye kuvandudza mashandiro ekutapurirana.
Zvadaro, kubva pamaonero matsva ekutapurirana midhiya, G.654E ultra-low-loss optical fiber ichava sarudzo yekutanga yetrunk network uye kusimbisa kutumirwa, uye icharamba ichidzidzira nzvimbo-division multiplexing optical fiber (cable). Spectrum, kunonoka kuderera, yakaderera nonlinear mhedzisiro, yakaderera kupararira, uye mamwe akawanda mabhenefiti akave akatarisana neindasitiri, ukuwo kurasikirwa kwekutapurirana uye kudhirowa kwakawedzerwa. Pamusoro pezvo, kubva pakuona tekinoroji uye kusimbiswa kwekukura kwechigadzirwa, kutarisisa kweindasitiri, zvichingodaro, vashandi vemudzimba vanotarisirwa kuburitsa mhenyu maratidziro emhando yepamusoro-speed masisitimu akadai seDP-QPSK 400G kureba kuita, 50G PON dual-mode kugarisana. uye symmetrical kutapurirana masimba muna 2023 Basa rekuongorora bvunzo rinoenderera mberi rinoratidza hukuru hwezvakajairwa high-speed interface zvigadzirwa uye rinoisa hwaro hwekutumirwa kwekutengesa.
Pakupedzisira, nekuvandudzwa kwe data interface rate uye simba rekuchinja, kubatanidzwa kwepamusoro uye kuderera kwesimba kushandiswa kwave kwave kudiwa kwekusimudzira kweiyo optical module yeiyo basic unit ye optical communication, kunyanya mune yakajairwa data center application scenarios, kana switch yasvika pa51.2. Tbit / s Uye pamusoro, iyo yakabatanidzwa fomu ye optical modules ine chiyero che800Gbit / s uye pamusoro inogona kutarisana nemakwikwi ekugarisana kwe pluggable uye photoelectric package (CPO). Zvinotarisirwa kuti makambani akadai seIntel, Broadcom, uye Ranovus acharamba achivandudza mukati megore rino Pamusoro pezvigadzirwa zveCPO zviripo uye mhinduro, uye anogona kuvhura mhando itsva dzechigadzirwa, mamwe makambani e-silicon photonics tekinoroji achateverawo nekushingaira mukutsvagisa nekusimudzira. kana kunyatsoteerera kwairi.
Uye zvakare, maererano neiyo photonic yekubatanidza tekinoroji yakavakirwa pane optical module maapplication, silicon photonics ichagarisana neIII-V semiconductor yekubatanidza tekinoroji, zvichipihwa kuti silicon photonics tekinoroji ine kusanganisa kwakanyanya, kumhanya kukuru, uye kuenderana kwakanaka neiripo CMOS maitiro Silicon photonics yave. zvishoma nezvishoma yakashandiswa mune zvepakati uye pfupi-kure pluggable optical modules, uye yave yekutanga yekuongorora mhinduro yekubatanidzwa kweCPO. Iyo indasitiri ine tarisiro nezve remangwana kuvandudzwa kwesilicon photonics tekinoroji, uye kuongorora kwayo kwekushandisa muoptical computing uye mamwe minda ichawiriraniswawo kuitwa.
