·Kulandila kukhudzika mpaka -25.5dBm
·Tumizani mphamvu mpaka -1 mpaka +4dBm
·PON imagwiritsa ntchito chingwe chimodzi cha kuwala kuti ilumikizane ndiOLT, ndipo kenakoOLTzikugwirizana ndiONU. ONUimapereka ntchito monga data, IPTV (mwachitsanzo, wailesi yakanema yolumikizana), mawu (pogwiritsa ntchito IAD, mwachitsanzo, Integrated Access Device) ndi mautumiki ena, kuzindikira "sewero-katatu"
·Mtengo wapamwamba kwambiri wa PON: symmetrical 1Gb/s kumtunda ndi kumunsi kwa data, mawu a VoIP ndi makanema a IP
·ONU"Pulagi ndi Sewerani" kutengera zodziwikiratu ndi kasinthidwe
·Advanced quality of service (QoS) ntchito zotengera kuyitanitsa kwa mgwirizano wa service (SLA).
·Kuthekera koyang'anira kutali komwe kumathandizidwa ndi ntchito zolemera komanso zamphamvu za OAM
·Kulandira kuwala kwamphamvu kwambiri komanso kugwiritsa ntchito mphamvu zochepa
