I-China Academy of Telecommunication Research iphumelele uvavanyo lwetekhnoloji yelabhoratri yezixhobo zasekhaya ze-50G-PON ezivela kubavelisi bezixhobo eziphambili zasekhaya, igxile ekuqinisekiseni ukwamkelwa kwe-uplink kabini kunye nomthamo wokuthwala iinkonzo ezininzi.

Itekhnoloji ye-50G-PON ibikwinqanaba lokuqinisekiswa kwesicelo esincinci, ijongene nomlinganiselo wezorhwebo wexesha elizayo, ishishini lasekhaya lixhomekeke kwi-upstream multi-rate reception, i-32dB optical power budget, i-3-mode OLT optical module miniaturization kunye nezinye iingxaki zobuchwepheshe kunye nobunjineli eziphambili, kodwa ikwakhuthaza ngenkuthalo inkqubo yendawo. NgoFebruwari kulo nyaka, i-China Academy of Telecommunication Research isekelwe kuphuhliso lwasekhaya lwe-50G-PON kunye neemfuno zesicelo, okokuqala kwi-ITU-T uplink convergence ukuya kwi-25G/50G uplink dual-rate reception capacity. Olu vavanyo luqinisekisile kakhulu amandla, kwaye i-throughput kunye nokuzinza kweshishini kufikelele kulindelo. Ukongeza, i-uplink optical power budget yezixhobo ezininzi inokufikelela kwinqanaba leKlasi C+ (32dB) ngesantya esingalinganiyo, ibeka isiseko se-25G/50G dual rate elandelayo ukuhlangabezana nenqanaba leKlasi C+. Olu vavanyo lukwaqinisekisa inkxaso ye-50G-PON yezakhono ezintsha zoshishino ezifana nokuzimisela.

Izixhobo ze-50G-PON ezivavanyiweyo ngeli xesha zisekelwe kwinkqubo entsha yezixhobo zekhompyutha zasekhaya, kwaye izinga lokufikelela kwindawo ngokubanzi lifikelele ngaphezulu kwe-90%, kwaye abanye abavelisi banokufikelela kwi-100%. I-China Academy of Telecommunication Research iza kuqhubeka nokusebenza namaqabane ukukhuthaza indawo kunye nolawulo oluzimeleyo lwe-50G-PON mveliso, isombulule ubuchwepheshe obuphambili kunye nezakhono zobunjineli ezifunekayo ekusetyenzisweni okukhulu kwezorhwebo, yenze uvavanyo lwentsimi ye-50G-PON kwiimeko ezahlukeneyo zoshishino, kwaye ihlangabezane neemfuno zokufikelela kwixesha elizayo zezicelo ezilishumi ezikrelekrele kakhulu ze-gigabit.
