Itekhnoloji ye-PON ibisoloko inamandla okuphinda izenzele kwaye iqhelane neemfuno ezintsha zentengiso. Ukusuka kwisantya serekhodi ukuya kwisantya sebit esiphindwe kabini kunye nee-lambda ezininzi, i-PON ibisoloko iligorha le-broadband, evumela ukwamkelwa kunye nokusebenza kweenkonzo ezintsha. Ukukhuthazwa kweshishini kunokwenzeka.
Njengoko inethiwekhi ye-5G iqala ukwakha, ibali le-PON livula kwakhona iphepha elitsha.Ngeli xesha, iteknoloji ye-PON yesizukulwana esilandelayo yamkela i-paradigm entsha ukufezekisa amandla aphezulu ngokufanelekileyo.I-PON ye-25G iya kusebenzisa i-ecosystem yedatha, kunokuba inkqubo yokudlulisela esetyenziswa kwimbali yeteknoloji yePON, emele isigaba esilandelayo se-fiber evolution, i-dimension entsha kwibali le-PON.
Ukusebenza kweendleko kungundoqo
Kukho iimfuno ezimbini zokufikelela kwitekhnoloji yempumelelo: ukusebenza kakuhle kweendleko kunye nemfuno yemarike. Ekuhanjisweni kwenethiwekhi yokufikelela kwinqanaba elikhulu, eyokuqala isitshixo. Ukusebenzisa i-ecosystem eqinisekisiweyo kunye nobuchwepheshe bokukhanya obuphezulu bunokunceda ukufikelela kwiindleko ezifanelekileyo ngelixa kuphuculwa ngakumbi ukuphumelela kweendleko ngokusekelwe kuphando kunye nokusungula.
Ngaloo ndlela, impumelelo yezorhwebo ye-25G PON iya kuxhomekeka kumandla ayo okubonelela ngamaxesha e-2.5 ngaphezulu kwe-bandwidth kune-10G PON ngexabiso eliphantsi. Ngethamsanqa, i-25G PON ineyona ndlela ingabizi kakhulu yokuhamba ngaphaya kwe-10G PON kuba iya kusebenzisa iteknoloji ye-25G ye-optical ephezulu esetyenziselwa ukudibanisa amaziko edatha.
Njengoko ukuhanjiswa kweziko ledatha kwanda, inani le-25G optics liya kwanda kwaye iindleko zesixhobo ziya kuncipha. Ngokuqinisekileyo, akunakwenzeka ukuba udibanise ngokuthe ngqo la macandelo edatha yedatha kwi-optical line ukupheliswa (OLT) kunye neyunithi yenethiwekhi yamehlo (I-ONU) ii-transceivers, eziza kufuna amaza amaza amatsha, amandla okuhambisa aphezulu othutho, kunye novakalelo oluphezulu lomamkeli.
Nangona kunjalo, oku akwahlukanga kwiiPON zesizukulwana sangaphambili zisebenzisa amacandelo asuka kwi-long-haul kunye ne-metro transceivers. Ukongeza, i-25G yitekhnoloji ye-TDM elula engadingi i-laser ebiza kakhulu.
Cacisa imeko yesicelo
Ngokumalunga nemfuno yemarike, into yesibini efunekayo kwimpumelelo ye-PON ye-25G kukuqinisekisa ukuba i-25G ineemeko ezicacileyo zokusetyenziswa, kubandakanywa indawo yokuhlala, yorhwebo, njalo njalo. Imarike yendawo yokuhlala inokubonelela ngethuba lokuhlanganisa iinkonzo zeGigabit kwiiPON eziphezulu; kwicandelo lezorhwebo, i-25G iya kubonelela nge-10G okanye iinkonzo eziphezulu zokwandisa iinkonzo kumashishini.
Ukongezelela, ngexesha le-5G, ukuhanjiswa kwexesha elide kufuna i-25G. Nangona i-XGS-PON okanye i-10G PTP inokusombulula ngokufanelekileyo i-middle-range kunye neengxaki ze-backhaul, ngenxa yokunyuka kwe-RF bandwidth kunye ne-MIMO ye-antenna layer, i-25G PON iyadingeka kwimeko yobuninzi obuphezulu kunye ne-cell single throughput. Ngexesha elifanayo, i-25G PON ihambelana ne-mobile network evolution kuba i-interface ye-25G yomzimba iya kusetyenziselwa zombini iiyunithi ezingundoqo kunye nokusabalalisa.
Ezinye izandi
Njengesiqhelo, ishishini lifunda iinketho ezahlukeneyo zokuzivelela kwePON. Ngokomzekelo, i-50G PON iphakanyisiwe, kodwa ibeka umngeni we-ecosystem wangaphambi kwexesha ongayi kuphucula kude kube ngu-2025, kwaye okwangoku akukho kubonakala kwi-50G yezoshishino.
Umzobo: Izizukulwana ezininzi zetekhnoloji yePON zixhomekeke kubuchwephesha obuqinisekisiweyo be-optical kunye ne-elektroniki.
Esinye isisombululo esicatshangelwayo kukwenza i-2x10G yokudibanisa kwii-wavelengths ezimbini ezingabonakaliyo. Isisombululo sisebenzisa ubude bemaza be-GPON kunye ne-XGS ye-wavelength. Ngelishwa, le ndlela izisa iindleko eziphezulu (ngokuphindwe kabini i-optics ye-10G), ukwanda kobunzima, kunye nokungabikho kokukwazi ukuhlala kunye nokuthunyelwa kwe-GPON yangoku, ngoko akukho sibheno semarike.
Ingxaki efanayo inokuthi yenzeke nge-2xTWDM ekubotshweni kwe-wavelength esebenzayo. I-TWDM sele ibiza kakhulu, ifuna iilaser ezimbini ukudibanisa ubude bamaza kwi-I-ONU, eyenza iindleko zokuthunyelwa kwizinga elikhulu ngakumbi.
I-25G PON yeyona ndlela isebenzayo yokuguqula inethiwekhi yefiber-optic kwisizukulwana esilandelayo, ubuchule obulula obusebenzisa i-wavelength enye kwaye ayifuni i-laser elungisiweyo.
Ihlala kunye ne-GPON kunye ne-XGS-PON kwaye inikezela ngamazinga aphezulu e-25Gb / s asezantsi kunye ne-25Gb / s okanye i-10Gb / s amazinga anyukayo. Ikwasekwe kwitekhnoloji ye-optical eqinisekisiweyo kunye ne-ecosystem eguqukayo eyenza le teknoloji iziswe kwintengiso ngokukhawuleza. Iyakwazi ukuhlangabezana noxinzelelo oluphezulu lweendawo zokuhlala, zorhwebo kunye nezinye iimfuno kwixesha elifutshane, ngelixa lijongene nosongelo olukhuphisanayo lwe-25G EPON kunye nabaqhubi bekhebula.
