Iyo OLT inopa madoko gumi nematanhatu e downlink 1000M EPON, doko re 4*GE SFP, doko re 4*GE COMBO uye doko re 2 *10G SFP re uplink. Kureba kwayo i1U chete kuti zvive nyore kuisa uye kuchengetedza nzvimbo. Inoshandisa tekinoroji yepamusoro, ichipa mhinduro inoshanda yeEPON. Uyezve, inochengetedza mari yakawanda kune vanoshanda nekuti inogona kutsigira network dzakasiyana dze ONU hybrid.
