Lefapheng la marangrang a puisano, ntshetsopele ya di-node tsa optical e fetoha haholo. Di-node tsena di bapala karolo ya bohlokwa phetisong ya matshwao a data, lentswe le video, mme ntshetsopele ya tsona e amme haholo bokgoni le lebelo la ditsamaiso tsa puisano tsa sejwalejwale. Ho blog ena, re tla hlahloba phetoho ya di-node tsa optical le karolo ya tsona phetohong ya marangrang a puisano.
Khopolo eali-node tsa mahloe qalile matsatsing a pele a 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 matšoao a motlakase le ka tsela e fapaneng. Li sebetsa e le ntlha ea khokahano lipakeng tsa marangrang a fiber optic le meralo ea motheo ea puisano e thehiloeng koporong. Leha ho le joalo, ha theknoloji e ntse e tsoela pele, karolo ea li-node tsa optical e ntse e atoloha, 'me li fetohile karolo ea bohlokoa haholo ho kenngoeng ha marangrang a puisano a tsoetseng pele.
E 'ngoe ea tsoelo-pele ea bohlokoa theknolojing ea li-node tsa optical ke kopanyo ea ts'ebetso ea wavelength division multiplexing (WDM). WDM e lumella melapo e mengata ea data ho fetisoa ka nako e le 'ngoe holim'a faeba e le 'ngoe ho sebelisoa maqhubu a fapaneng a leseli. Theknoloji ena e eketsa haholo bokhoni le katleho ea marang-rang a optical, e nolofalletsang phetiso ea data e ngata ka lebelo le phahameng.
Ntlafatso e 'ngoe e kholo theknolojing ea li-node tsa optical ke ho kopanngoa ha li-amplifier tsa optical. Li-amplifier tsena li sebelisetsoa ho eketsa matla a matšoao a optical, li li lumella ho fetisoa libakeng tse kholo ntle le tlhoko ea lisebelisoa tse turang le tse rarahaneng tsa ho nchafatsa matšoao. Ho kenyelletsoa ha li-amplifier tsa optical ka har'a li-node tsa optical ho fetotse papali bakeng sa marang-rang a puisano a hole, ho nolofalletsa ho kenngoa ha likhokahano tse nang le bokhoni bo phahameng le tse potlakileng libakeng tse telele.
Ho phaella moo, ntshetsopele ya di-node tsa optical e lebisitse ntshetsopeleng ya di-multiplexers tse ka hlophiswang botjha tsa optical add-drop (DI-ROADM). Disebediswa tsena di dumella basebetsi ba marangrang ho hlophisa botjha ditsela tsa optical ka hare ho marangrang a bona, ho nolofalletsa kabo e matla ya bandwidth le ho eketsa ho tenyetseha ha marangrang. Di-node tsa optical tse sebediswang ke ROADM di bapala karolo ya bohlokwa ho kenngweng ha marangrang a puisano a potlakileng, a feto-fetohang a kgonang ho fihlela ditlhoko tse ntseng di hola tsa bandwidth le kgokelo.
Tsoelo-pele ea morao tjena theknolojing ea li-node tsa optical e kenyelletsa kopanyo ea bokhoni ba marang-rang a bohlale a hlalositsoeng ke software (SDN). Sena se lumella taolo le tsamaiso ea marang-rang a optical e bohareng, e nolofalletsang ho hlophisoa ho matla ha mehloli ea marang-rang le boenjiniere bo sebetsang ba sephethephethe. Li-node tsa optical tse sebelisoang ke SDN li bula tsela bakeng sa nts'etsopele ea marang-rang a puisano a itlhophisang le a ipholisang, a khonang ho ikamahanya le maemo a fetohang a marang-rang ka nako ea sebele.
Ka bokhutšoanyane, nts'etsopele eali-node tsa mahloe bapetse karolo ea bohlokoa phetohong ea marangrang a puisano. Ho tloha lisebelisoa tse bonolo tsa ho fetola matšoao ho ea ho likarolo tse rarahaneng tsa marangrang a bohlale, li-node tsa optical li bapala karolo ea bohlokoa ho nolofatseng ho kenngoa ha marangrang a puisano a nang le bokhoni bo phahameng le a lebelo le phahameng. Ha theknoloji e ntse e tsoela pele ho hatela pele, re ka lebella liphetoho tse ling theknolojing ea li-node tsa optical, e leng se tsamaisang phetoho e tsoelang pele ea marangrang a puisano le ho bopa bokamoso ba khokahano.
