Khopolo eali-node tsa opticale qalile mehleng ea pele ea theknoloji ea fiber optic.Qalong, li-node tsena e ne e le lisebelisoa tse bonolo tse sebelisetsoang ho fetola matšoao a optical hore e be lipontšo tsa motlakase le ka tsela e fapaneng.Li sebetsa e le sebaka sa khokahano lipakeng tsa marang-rang a fiber optic le meaho ea likhokahanyo ea setso e thehiloeng koporo.Leha ho le joalo, ha theknoloji e ntse e hatela pele, karolo ea li-optical node e ntse e eketseha, 'me e fetohile karolo ea bohlokoa haholo ho romelleng marang-rang a tsoetseng pele a puisano.
E 'ngoe ea tsoelo-pele ea bohlokoa ho theknoloji ea optical node ke ho kopanngoa ha wavelength division multiplexing (WDM) tshebetso.WDM e lumella melapo e mengata ea data hore e fetisetsoe ka nako e le 'ngoe holim'a fiber e le' ngoe e sebelisa maqhubu a fapaneng a khanya.Theknoloji e eketsa haholo bokhoni le bokhoni ba marang-rang a optical, e leng ho nolofalletsang ho fetisoa ha lintlha tse ngata ka lebelo le phahameng.
Khatelo-pele e 'ngoe e kholo ea theknoloji ea optical node ke ho kopanya li-amplifiers tsa optical.Li-amplifiers tsena li sebelisetsoa ho eketsa matla a matšoao a optical, ho li lumella hore li fetisetsoe libakeng tse hōle ntle le tlhokahalo ea lisebelisoa tse theko e boima le tse rarahaneng tsa ho tsosolosa matšoao.Ho kenngoa ha li-amplifiers tsa optical ho li-node tsa optical ho fetotse papali bakeng sa marang-rang a marang-rang a nako e telele, e leng ho nolofalletsang ho romelloa ha likhokahano tse phahameng, tse lebelo le phahameng ka nako e telele.
Ho phaella moo, nts'etsopele ea li-node tsa optical li lebisitse ho nts'etsopele ea li-multiplexers tsa optical add-drop (ROADMs).Lisebelisoa tsena li lumella basebelisi ba marang-rang hore ba boele ba hlophise litsela tsa optical ka har'a marang-rang a bona, ho etsa hore kabo e matla ea bandwidth le ho eketsa maemo a marang-rang.Li-node tsa optical tse nolofalitsoeng ke ROADM li phetha karolo ea bohlokoa ho fetisetsoeng ha marang-rang a khale, a feto-fetohang a khonang ho finyella litlhoko tse ntseng li eketseha tsa bandwidth le khokahanyo.
