Ndemanga Zachidule JHA700-G504 mndandanda wa GPON ONT ndi imodzi mwamapangidwe amtundu wa GPON optical network kuti akwaniritse zofunikira za netiweki yofikira pa burodibandi. Imagwira ntchito mu FTTH/FTTO kuti ipereke data, ntchito yamavidiyo yochokera pa netiweki ya GPON. GPON ndi mibadwo yaposachedwa yaukadaulo wapaintaneti. ITU-T G.984 ndi protocol yokhazikika ya GPON. Muyezo wa GPON umasiyana ndi miyezo ina ya PON chifukwa imakwaniritsa bandwidth yapamwamba komanso yogwira ntchito kwambiri pogwiritsa ntchito mapaketi akuluakulu, osinthasintha. GPON imapereka kulongedza bwino kwa kuchuluka kwa anthu ogwiritsa ntchito, ndikugawa magawo omwe amalola kuti mautumiki apamwamba (QOS) azitha kulumikizana ndi mawu komanso makanema. Maukonde a GPON amapereka kudalirika ndi magwiridwe antchito omwe amayembekezeredwa pamabizinesi ndipo amapereka njira yowoneka bwino yoperekera ntchito zogona. GPON imathandizira kutumizidwa kwa Fiber To The Home (FTTH) mwachuma zomwe zimabweretsa kukula kwachuma padziko lonse lapansi. JHA700--504 mndandanda ndi kudalirika mkulu ndi kupereka khalidwe chitsimikizo utumiki, kasamalidwe zosavuta, kukulitsa kusintha ndi maukonde.
