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; network yekutumira inotungamirirwa ne100G / 200G kukurumidza Kuwedzera, chikamu che400G data center mukati kana kunze kwekubatana kwepamusoro inotarisirwa kuwedzera zvakanyanya, asi 800G / 1.2T / 1.6T uye imwe yepamusoro yekugadzirwa kwechigadzirwa uye tsvakurudzo yehutano hwepamusoro inosimudzirwa pamwe chete, uye mamwe ekunze optical communication centre inotarisirwa kusunungura dhigirii repamusoro rekugadzira DSP kana kuti chipfambi chepamusoro chekugadzira zvigadzirwa zveDSP .
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, nezvimwewo, vashandi vemudzimba vanotarisirwa kuburitsa mhenyu maratidziro emhando yepamusoro-speed masisitimu akadai seDP-QPSK 400G kureba kuita, 50G PON mbiri-mode kugarisana uye symmetrical kutapurirana masimba muna 2023 yakawedzera bvunzo yekuwedzera bvunzo. zvigadzirwa uye inoisa hwaro hwekutengesa kwekutengesa.
Pakupedzisira, nekuvandudzwa kwe data interface rate uye simba rekushandura, kubatanidzwa kwepamusoro uye kushandiswa kwesimba zvishoma zvave izvo zvinodikanwa zvekusimudzira kweiyo optical module yeiyo basic unit ye optical communication, kunyanya mune yakajairwa data center application scenarios, kana switch yesimba inosvika 51.2Tbit / s Uye pamusoro, iyo yakabatanidzwa fomu ye optical module ine chiyero che800Gbit / selectric pasuru uye inogoneka pasuru inogona kutarisana nemakwikwi epamhepo. (CPO). Zvinotarisirwa kuti makambani akadai seIntel, Broadcom, uye Ranovus acharamba achivandudza mukati megore rino Pamusoro pezvigadzirwa zveCPO zviripo uye zvigadziriso, uye zvingangotanga zvitsva zvechigadzirwa, mamwe makambani e-silicon photonics tekinoroji achaitawo kushingaira kutevera pakutsvakurudza nekusimudzira kana kunyatsoteerera.
Pamusoro pezvo, maererano neiyo photonic yekubatanidza tekinoroji yakavakirwa pane optical module application, silicon photonics ichagarisana neIII-V semiconductor yekubatanidza tekinoroji, zvichipihwa kuti silicon photonics tekinoroji ine yakanyanya kubatanidzwa, kukurumidza kukurumidza, uye kuenderana kwakanaka nearipo CMOS maitiro Silicon photonics yakashandiswa zvishoma nezvishoma mukati uye pfupi-kure pluggable pluggable inova yekutanga mhinduro yeCPO. Iyo indasitiri ine tarisiro nezve remangwana kuvandudzwa kwesilicon photonics tekinoroji, uye kuongorora kwayo kwekushandisa muoptical computing uye mamwe minda ichawiriraniswawo kuitwa.
