Bungwe la China Academy of Telecommunication Research lamaliza bwino mayeso aukadaulo wa labu a zida zapakhomo za 50G-PON kuchokera kwa opanga zida ambiri apakhomo, poyang'ana kwambiri pakutsimikizira kuti zida za uplink ziwiri ndi zonyamula zambiri.

Ukadaulo wa 50G-PON wakhala mu gawo lotsimikizira ntchito zazing'ono, ukukumana ndi kukula kwamalonda mtsogolo, makampani akunyumba ali ndi njira yolandirira zinthu zambiri, bajeti yamagetsi yamagetsi ya 32dB, miniaturization ya 3-mode OLT optical module ndi mavuto ena ofunikira aukadaulo ndi uinjiniya, komanso kulimbikitsa mwachangu njira yolumikizira malo. Mu February chaka chino, China Academy of Telecommunication Research idakhazikitsa chitukuko cha mafakitale a 50G-PON ndi zosowa zawo, koyamba mu ITU-T uplink convergence ku 25G/50G uplink dual-rate receiver. Mayesowa adatsimikizira makamaka kuthekera, ndipo throughput ndi kukhazikika kwa bizinesi zidafika pamlingo woyembekezeredwa. Kuphatikiza apo, bajeti yamagetsi yamagetsi ya uplink ya zida zambiri imatha kufika pamlingo wa Class C+ (32dB) pamlingo wosagwirizana, ndikuyika maziko a 25G/50G dual rate kuti ikwaniritse mulingo wa Class C+. Mayesowa amatsimikiziranso kuthandizira kwa 50G-PON pazinthu zatsopano zamabizinesi monga determinism.

Zipangizo za 50G-PON zomwe zayesedwa nthawi ino zimachokera ku makina atsopano a zida zapakhomo, ndipo kuchuluka kwa malo omwe alipo kwafika pa 90%, ndipo opanga ena amatha kufika pa 100%. China Academy of Telecommunication Research ipitiliza kugwira ntchito ndi othandizana nawo kuti ilimbikitse malo ndi kuwongolera kwa unyolo wa mafakitale wa 50G-PON kuyambira kumapeto mpaka kumapeto, kuthetsa ukadaulo wofunikira ndi luso la uinjiniya lofunikira pakugwiritsa ntchito kwakukulu kwamalonda, kuchita mayeso amunda a 50G-PON pazinthu zosiyanasiyana zamabizinesi, ndikukwaniritsa zosowa zamtsogolo za ma gigabit khumi anzeru kwambiri.
