Munyaya dzema network ekutaurirana, kukura kwema optical nodes kunochinja-chinja. Ma nodes aya anoita basa guru mukutumira data, izwi nemavhidhiyo, uye kukura kwawo kwakakanganisa zvakanyanya kushanda nekumhanya kwema system ekutaurirana emazuva ano. Mublog rino, tichaongorora kushanduka kwema optical nodes nebasa rawo mukuchinja kwema network ekutaurirana.
Pfungwa yemafundo emazisoinotangira pamazuva ekutanga kwetekinoroji yefiber optic. Pakutanga, ma node aya aive zvishandiso zviri nyore zvaishandiswa kushandura masaini e optic kuita masaini emagetsi uye zvinopesana. Anoshanda senzvimbo yekubatanidza pakati pema network e fiber optic nezvivakwa zvekutaurirana zvechinyakare zve copper-based. Zvisinei, sezvo tekinoroji ichifambira mberi, basa rema node e optical rinoramba richikura, uye ave chinhu chakakosha mukushandiswa kwema network ekukurukurirana epamusoro.
Imwe yenzira dzakakosha dzekuvandudza tekinoroji ye optical node ndeyekubatanidza mashandiro e wavelength division multiplexing (WDM). WDM inobvumira kuti data streams dzakawanda dzitumirwe panguva imwe chete pamusoro pe fiber imwe chete uchishandisa ma wavelength akasiyana echiedza. Iyi tekinoroji inowedzera zvakanyanya kugona uye kushanda zvakanaka kwema optical network, zvichiita kuti data rakawanda ritumirwe nekukurumidza.
Imwe nzira huru yekuvandudza tekinoroji yema "optical node" ndeyekubatanidza ma "optical amplifiers". Ma "amplifiers" aya anoshandiswa kuwedzera simba re "optical signals", zvichibvumira kuti atumirwe kure kure pasina kudiwa kwemidziyo inodhura uye yakaoma yekugadzirisa ma "signal". Kubatanidzwa kwema "optical amplifiers" muma "optical nodes" kwakachinja mutambo wema "long-distance communication networks", zvichigonesa kuiswa kwe "high-capacity, high-speed connections" munzvimbo refu.
Pamusoro pezvo, kugadzirwa kwema optical nodes kwakatungamira mukugadzirwa kwema optical add-drop multiplexers (ROADMs). Midziyo iyi inobvumira vashandisi ve network kugadzirisa nzira dze optical vari kure mukati mema network avo, zvichigonesa kugoverwa kwe bandwidth uye kuwedzera kushanduka kwe network. Ma optical nodes anogoneswa ne ROADM anoita basa rakakosha mukushandiswa kwema network ekukurukurirana anochinjika uye anochinjika anokwanisa kusangana nezvinodiwa zviri kukura zve bandwidth uye kubatana.
Kufambira mberi kwazvino mu tekinoroji ye optical node kunosanganisira kubatanidzwa kwehunyanzvi hwe intelligent software-defined networking (SDN). Izvi zvinobvumira kudzora nekutarisira ma optical networks pakati, zvichigonesa dynamic configuration ye network resources uye efficiency traffic engineering. SDN-enabled optical nodes dzinovhura nzira yekuvandudza ma network ekukurukurirana anozvigadzirisa uye anozviporesa, anokwanisa kugadzirisa mamiriro e network anochinja munguva chaiyo.
Muchidimbu, kukura kwemafundo emazisoyakatora basa rakakosha mukuchinja kwema network ekutaurirana. Kubva pamidziyo iri nyore yekushandura masaini kusvika kuzvikamu zvakaoma zve network zvine hungwaru, ma optical nodes anoita basa rakakosha mukugonesa kuiswa kwema network ekukurukurirana ane simba guru uye anomhanya zvakanyanya. Sezvo tekinoroji ichiramba ichifambira mberi, tinogona kutarisira zvimwe zvitsva mu tekinoroji ye optical node, zvichitungamira kushanduka kuri kuramba kuripo kwema network ekutaurirana uye kuumba ramangwana rekubatana.
