Mazwi akakosha: kuwedzera kugona kwenetwork ye optical, kuvandudzwa kwetekinoroji kunoramba kuripo, mapurojekiti ekuongorora einterface yekumhanya kwepamusoro akatanga zvishoma nezvishoma
Munguva yesimba remakombiyuta, nekushingaira kukuru kwemasevhisi matsva nemashandisirwo, matekinoroji ekuvandudza kugona kwemakombiyuta akawanda akadai sehuwandu hwemasaini, upamhi hwemaspectral huripo, multiplexing mode, uye nzira itsva dzekutumira data dziri kuramba dzichigadzira nekuvandudza.
Chekutanga, kubva pamaonero ekuwedzera kwehuwandu hwechiratidzo chemugero kana chenji, chiyero che10G PONKuiswa kwenetwork yekupinda kwakawedzerwa, mwero wehunyanzvi we50G PON wagara wakadzikama, uye makwikwi emhinduro dzehunyanzvi dze100G/200G PON akanyanya; network yekutumira inotongwa ne100G/200G speed Expansion, huwandu hwe400G data centre internal kana external interconnection rate hunotarisirwa kuwedzera zvakanyanya, nepo 800G/1.2T/1.6T nedzimwe mhando dzezvigadzirwa zvepamusoro uye ongororo yehunyanzvi zviri kukurudzirwa pamwe chete, uye vagadziri vekunze vemaoptical communication head vanotarisirwa kuburitsa 1.2T kana yepamusoro coherent DSP processing chip products kana public development plans.
Chechipiri, kubva pakuona kwespectrum iripo yekutumira, kuwedzera zvishoma nezvishoma kwebhendi reC-band rekutengesa kuenda kubhendi reC+L kwave mhinduro yekubatana muindasitiri. Zvinotarisirwa kuti mashandiro ekutumira marebhutari acharamba achivandudzwa gore rino, uye panguva imwe chete kuramba vachiita tsvakiridzo pamaspectrum akafara akadai sebhendi reS+C+L.
Chechitatu, kubva pakuona kwe signal multiplexing, space division multiplexing tekinoroji ichashandiswa senzira yenguva refu yekugadzirisa dambudziko re transmission capacity. Sisitimu ye submarine cable yakavakirwa pakuwedzera zvishoma nezvishoma huwandu hwe optical fiber pairs icharamba ichishandiswa uye ichiwedzerwa. Zvichibva pa mode multiplexing uye/kana multiple Tekinoroji ye core multiplexing icharamba ichidzidzwa zvakadzama, ichitarisa pakuwedzera daro re transmission uye kuvandudza mashandiro e transmission.
Zvadaro, kubva pamaonero ezvekutumira zvinhu zvitsva, G.654E ultra-low-loss optical fiber ichave sarudzo yekutanga ye trunk network uye kusimbisa kuiswa, uye icharamba ichidzidza nezve space-division multiplexing optical fiber (tambo). Spectrum, low delay, low nonlinear effect, low dispersion, nezvimwe zvakanakira zvakawanda zvave chinangwa cheindasitiri, nepo kutapurirana kwekurasikirwa nekudhirowa kwave kuchiwedzerwa. Pamusoro pezvo, kubva pamaonero etekinoroji uye kusimbiswa kwekukura kwechigadzirwa, kutarisisa kwekuvandudzwa kweindasitiri, nezvimwewo, vashandi vemuno vanotarisirwa kutanga network dze high-speed systems dzakadai seDP-QPSK 400G long-distance performance, 50G PON dual-mode coexistence uye symmetrical transmission capabilities muna 2023 Basa rekuongorora bvunzo rinosimbisa kukura kwezvigadzirwa zve high-speed interface uye rinoisa hwaro hwekushandiswa kwekutengeserana.
Pakupedzisira, nekuvandudzika kwehuwandu hwedata interface uye kugona kwekuchinja, kubatanidzwa kwakanyanya uye kushandiswa kwesimba kwakaderera zvave zvinodiwa pakugadzirwa kwe optical module ye basic unit ye optical communication, kunyanya mune zvakajairika data center application scenarios, apo kugona kwe switch kunosvika 51.2Tbit/s Uye pamusoro, fomu yakabatanidzwa yema optical modules ane chiyero che800Gbit/s zvichikwira anogona kusangana nemakwikwi e coexistence e pluggable ne photoelectric package (CPO). Zvinotarisirwa kuti makambani akadai seIntel, Broadcom, naRanovus acharamba achivandudza mukati megore rino. Kuwedzera kune zvigadzirwa nemhinduro zveCPO zviripo, uye anogona kutanga mamodheru matsva ezvigadzirwa, mamwe makambani e silicon photonics tekinoroji acharamba achiteverawo tsvakiridzo nekuvandudzwa kana kunyatsoteerera.
Pamusoro pezvo, maererano netekinoroji yekubatanidza photonic yakavakirwa pakushandiswa kwe optical module, silicon photonics ichashanda pamwe chete netekinoroji yekubatanidza semiconductor yeIII-V, zvichipiwa kuti tekinoroji yesilicon photonics ine kubatanidzwa kwakanyanya, kumhanya kwakanyanya, uye inoenderana zvakanaka nemaitiro aripo eCMOS. Silicon photonics yave ichishandiswa zvishoma nezvishoma mumamodule e optical anodzvanywa pakati nepakati uye mapfupi, uye yave mhinduro yekutanga yekutsvaga yekubatanidzwa kweCPO. Indasitiri iyi ine tariro nezvekuvandudzwa kwetekinoroji ye silicon photonics mune ramangwana, uye kuongorora kwayo mashandisirwo mu optical computing nedzimwe nzvimbo kuchaitwawo pamwe chete.
