Mumunda wekutaurirana network, kuvandudzwa kwemanode optical ndiko kushanduka.Aya ma node anoita basa rakakosha mukufambiswa kwedhata, izwi uye zviratidzo zvevhidhiyo, uye kukura kwavo kwakanganisa zvakanyanya kushanda nekumhanya kwemaitiro emazuva ano ekutaurirana.Mune ino blog, isu tichaongorora shanduko ye optical node nebasa radzo mukufambiswa kwenetwork network.
Pfungwa yeoptical nodesyakadzokera kumazuva ekutanga efiber optic tekinoroji.Pakutanga, node idzi dzaive midziyo yakapfava yaishandiswa kushandura masaini emagetsi kuita masaini emagetsi uye neimwe nzira.Ivo vanoshanda senzvimbo yekubatanidza pakati pefiber optic network uye yechinyakare mhangura-yakavakirwa kutaurirana zvivakwa.Nekudaro, sezvo tekinoroji inofambira mberi, basa remanodhi ekuona rinoramba richikura, uye rave chinhu chakakosha mukufambiswa kwemafambisirwo ekufambiswa kwemashoko.
Imwe yekufambira mberi kwakakosha mu optical node tekinoroji ndeyekubatanidzwa kwewavelength division multiplexing (WDM) mashandiro.WDM inobvumira nzizi dzedhata dzakawanda kuti dzifambiswe panguva imwe chete pamusoro pefiber imwe chete uchishandisa wavelengths dzakasiyana dzechiedza.Iyo tekinoroji inowedzera zvakanyanya kugona uye kugona kwe optical network, ichigonesa kutapurirana kwehuwandu hwakawanda hwe data nekumhanya kwakanyanya.
Imwe budiriro huru mu optical node tekinoroji ndeyekubatanidzwa kwe optical amplifiers.Aya maamplifiers anoshandiswa kuwedzera simba remaziso masaini, achibvumira kuti aendeswe pamusoro pemarefu madaro pasina kudiwa kweinodhura uye yakaoma chiratidzo chekuvandudza michina.Kubatanidzwa kweoptical amplifiers mu optical nodes yakashandura mutambo wehurefu hwekutaurirana network, zvichiita kuti kutumirwa kwepamusoro-soro, kushamwaridzana kwepamusoro-soro pamusoro pemarefu marefu.
Pamusoro pezvo, kuvandudzwa kwemanode optical kwaita kuti pave nekuvandudzwa kweanogadziriswa optical add-drop multiplexers (ROADMs).Zvishandiso izvi zvinobvumira vashandisi venetiweki kuti vagadzirise kure kure nzira dzemaziso mukati metiweki yavo, zvichigonesa kugoverwa kwe bandwidth uye kuwedzera network kuchinjika.ROADM-inogonesa optical node inoita basa rakakosha mukutumirwa kweagile, inochinjika yekutaurirana network inokwanisa kusangana nekukura kwekuda kwebandwidth uye yekubatanidza.
Kufambira mberi kwazvino mu optical node tekinoroji inosanganisira kubatanidzwa kwehungwaru software-inotsanangurwa networking (SDN) kugona.Izvi zvinobvumira centralized kudzora uye manejimendi eOptical network, ichigonesa dhizaini gadziriso yetiweki zviwanikwa uye inoshanda traffic traffic.SDN-inogonesa optical node inovhura nzira yekuvandudza yekuzvigadzirisa uye yekuzvirapa yekutaurirana network, inokwanisa kuchinjika nekuchinja network mamiriro munguva chaiyo.
Muchidimbu, kuvandudzwa kweoptical nodesyakaita basa rinokosha mukushandurwa kwematanho ekutaurirana.Kubva pazvishandiso zviri nyore zvekushandura zviratidzo kusvika kune zvakaomarara zvehungwaru network zvikamu, optical node dzinoita basa rakakosha mukugonesa kuiswa kwepamusoro-soro, kukurumidza-kumhanya network network.Sezvo tekinoroji ichiramba ichifambira mberi, tinogona kutarisira kuenderera mberi nehunyanzvi mune yekuona tekinoroji tekinoroji, tichityaira kuenderera mberi kwekushanduka kwematanho ekutaurirana uye kuumba ramangwana rekubatana.
