G.652D te muka whatu aratau-tahi (B1.3)
1. He pai mo nga momo hanganga taura muka whatu katoa: momo ngongo kurupae kurupae pokapū, momo paea paparanga karekau wewete, momo anga anga, hanganga taura muka;
2. Ko nga tono o te muka whatu ko: nga punaha whatu muka e hiahia ana ki te ngaronga iti me te bandwidth teitei, penei i te whakawhitiwhitinga tawhiti, nga raina pouaka, nga kaiwhangai porowhita, nga raina tohatoha me te pouaka whakaata, me etahi atu, he mea tino pai mo te roopu 1383nm roangaru roangaru wehenga multiplexing ( CWDM), te roangaru whakareatanga multiplexing (DWDM) me nga momo whakamahinga taiao motuhake (hei tauira, Uira-tohu OPGW taura whatu, ADSS taura whatu, me etahi atu), te muka whatu i roto i te rama motuhake rongoa paninga rauemi me te tukanga paninga me muri i te tukatuka, kia he pai ake te mahi i roto i nga taonga miihini me te mahi taiao teitei.
