Chisinthiko cha Optical Nodes: Revolution in Communications Networks

Pankhani ya maukonde olumikizirana, chitukuko cha ma optical node ndikusintha. Nodezi zimagwira ntchito yofunika kwambiri potumiza zizindikiro za deta, mawu ndi mavidiyo, ndipo chitukuko chawo chakhudza kwambiri mphamvu ndi liwiro la machitidwe amakono olankhulana. Mu blog iyi, tiwona kusinthika kwa ma optical node ndi gawo lawo pakusintha kwa netiweki yolumikizirana.

Lingaliro laoptical mfundoidayamba kale m'masiku oyambilira aukadaulo wa fiber optic. Poyambirira, mfundozi zinali zipangizo zosavuta zomwe zimagwiritsidwa ntchito potembenuza zizindikiro za kuwala kukhala zizindikiro zamagetsi ndi mosemphanitsa. Amakhala ngati malo olumikizirana pakati pa maukonde a fiber optic ndi njira zolumikizirana zamkuwa zachikhalidwe. Komabe, pamene teknoloji ikupita patsogolo, ntchito ya optical node ikupitirira kukula, ndipo akhala gawo lofunika kwambiri pa kutumizidwa kwa maukonde apamwamba.

Chimodzi mwazofunikira kwambiri paukadaulo wa optical node ndikuphatikiza magwiridwe antchito a wavelength division multiplexing (WDM). WDM imalola kuti mitsinje yambiri ya data ifalitsidwe nthawi imodzi pa fiber imodzi pogwiritsa ntchito mafunde osiyanasiyana a kuwala. Ukadaulo umakulitsa kwambiri mphamvu ndi magwiridwe antchito a optical network, zomwe zimathandizira kutumiza kwa data yambiri pa liwiro lalikulu.

Chitukuko china chachikulu muukadaulo wa optical node ndikuphatikiza ma amplifiers owoneka. Ma amplifierswa amagwiritsidwa ntchito kuti awonjezere mphamvu za zizindikiro za kuwala, zomwe zimalola kuti ziperekedwe pamtunda waukulu popanda kufunikira kwa zipangizo zopangira zowonetsera zokwera mtengo komanso zovuta. Kuphatikizika kwa optical amplifiers mu optical nodes kwasintha masewerawa kwa maukonde olankhulana mtunda wautali, zomwe zimathandiza kuti pakhale maulendo apamwamba, othamanga kwambiri pamtunda wautali.

Kuphatikiza apo, kupangidwa kwa ma optical node kwapangitsa kuti pakhale ma reconfigurable optical add-drop multiplexers (ROADMs). Zipangizozi zimalola ogwiritsa ntchito ma netiweki kukonzanso njira zowonekera mkati mwamanetiweki awo, kupangitsa kugawa kwamphamvu kwa bandwidth ndikuwonjezera kusinthasintha kwa maukonde. ROADM-yothandizira ma optical node amagwira ntchito yofunika kwambiri pakutumiza ma netiweki osavuta, osinthika omwe amatha kukwaniritsa zomwe zikukulirakulira kwa bandwidth ndi kulumikizana.

Kupita patsogolo kwaposachedwa kwaukadaulo wa optical node kumaphatikizapo kuphatikiza luso lanzeru la software-defined networking (SDN). Izi zimalola kuwongolera kwapakati ndi kasamalidwe ka ma network optical, kupangitsa kusinthika kosinthika kwazinthu zama network komanso uinjiniya wabwino wamayendedwe. Ma SDN opangidwa ndi ma optical node amathandizira kuti pakhale njira zolumikizirana zodzipangira zokha komanso zodzichiritsa zokha, zomwe zimatha kusintha kusintha kwa maukonde munthawi yeniyeni.

Mwachidule, chitukuko chaoptical mfundoyathandiza kwambiri pakusintha njira zolumikizirana. Kuchokera pazida zosavuta zosinthira ma siginecha kupita kumagulu anzeru anzeru amtaneti, ma node owoneka bwino amagwira ntchito yofunika kwambiri pakupangitsa kuti pakhale ma network apamwamba kwambiri, othamanga kwambiri. Pamene teknoloji ikupitirirabe patsogolo, tikhoza kuyembekezera kupititsa patsogolo luso lamakono la optical node, kuyendetsa kupitiriza kusinthika kwa maukonde olankhulana ndikusintha tsogolo la kulumikizana.
