Kwicandelo leenethiwekhi zonxibelelwano, uphuhliso lwee-optical nodes luyinto entsha. Ezi nodes zidlala indima ebalulekileyo ekudlulisweni kwedatha, ilizwi kunye nemiqondiso yevidiyo, kwaye uphuhliso lwazo luchaphazele kakhulu ukusebenza kakuhle kunye nesantya seenkqubo zonxibelelwano zanamhlanje. Kule blog, siza kuhlola uphuhliso lwee-optical nodes kunye nendima yazo kuguquko lwenethiwekhi yonxibelelwano.
Ingcamango yokubaamaqhuqhuva opticaliqala kwimihla yokuqala yetekhnoloji ye-fiber optic. Ekuqaleni, la ma-node ayezizixhobo ezilula ezisetyenziselwa ukuguqula ama-optical signals abe ngama-electrical signals kwaye ngokuchaseneyo. Asebenza njengendawo yokudibanisa phakathi kwama-fiber optic networks kunye neziseko zonxibelelwano zendabuko ezisekelwe kubhedu. Nangona kunjalo, njengoko iteknoloji iqhubela phambili, indima yama-optical nodes iyaqhubeka nokukhula, kwaye abe yinxalenye ebalulekileyo ekusetyenzisweni kwama-intanethi onxibelelwano aphambili.
Enye yeendlela eziphambili zokuphucula ubuchwepheshe be-optical node kukudityaniswa kokusebenza kwe-wavelength division multiplexing (WDM). I-WDM ivumela ukuba imijelo yedatha emininzi idluliselwe ngaxeshanye phezu kwefayibha enye kusetyenziswa ubude obahlukeneyo bokukhanya. Le teknoloji inyusa kakhulu amandla kunye nokusebenza kakuhle kweenethiwekhi ze-optical, ivumela ukuhanjiswa kwedatha eninzi ngesantya esiphezulu.
Olunye uphuhliso olukhulu kubuchwepheshe bee-node ze-optical kukuhlanganiswa kwee-amplifiers ze-optical. Ezi amplifiers zisetyenziselwa ukwandisa amandla eesignali ze-optical, ezivumela ukuba zidluliselwe kumgama omde ngaphandle kwesidingo sezixhobo zokuvuselela iisignali ezibizayo nezintsonkothileyo. Ukufakwa kwee-amplifiers ze-optical kwii-node ze-optical kutshintshe umdlalo kwiinethiwekhi zonxibelelwano ezikude, okuvumela ukuthunyelwa kwee-connections ezinomthamo ophezulu, ezikhawulezayo kumgama omde.
Ukongeza, uphuhliso lwee-optical nodes lukhokelele ekuphuhlisweni kwee-optical add-drop multiplexers (ii-ROADM). Ezi zixhobo zivumela abaqhubi benethiwekhi ukuba baphinde balungiselele iindlela ze-optical ngaphakathi kwenethiwekhi zabo, nto leyo evumela ukwabiwa kwe-bandwidth enamandla kunye nokwandisa ukuguquguquka kwenethiwekhi. Ii-optical nodes ezinikwe amandla yi-ROADM zidlala indima ebalulekileyo ekusetyenzisweni kweenethiwekhi zonxibelelwano eziguquguqukayo nezikwaziyo ukuhlangabezana neemfuno ezikhulayo ze-bandwidth kunye noqhagamshelwano.
Inkqubela phambili yakutshanje kubuchwepheshe be-optical node iquka ukudityaniswa kwezakhono ze-software-defined networking (SDN). Oku kuvumela ulawulo oluphakathi kunye nolawulo lwee-optical networks, okuvumela uqwalaselo oluguquguqukayo lwezixhobo ze-network kunye nobunjineli be-traffic obusebenzayo. Ii-optical nodes ezinikwe amandla yi-SDN zivula indlela yophuhliso lwee-self-optimization and self-healing networks, ezikwaziyo ukuziqhelanisa neemeko ze-network ezitshintshayo ngexesha langempela.
Ngamafutshane, uphuhliso lweamaqhuqhuva opticalidlale indima ebalulekileyo kuguquko lweenethiwekhi zonxibelelwano. Ukusuka kwizixhobo ezilula zokuguqula isignali ukuya kwizinto ezintsonkothileyo zenethiwekhi ekrelekrele, ii-optical nodes zidlala indima ebalulekileyo ekwenzeni ukuba kusetyenziswe iinethiwekhi zonxibelelwano ezinomthamo ophezulu nezikhawulezayo. Njengoko iteknoloji iqhubeka ihambela phambili, sinokulindela phambili kwiinguqulelo ezintsha kwiteknoloji yee-optical node, eziqhuba ukuvela okuqhubekayo kweenethiwekhi zonxibelelwano kunye nokubumba ikamva lonxibelelwano.
