G.652D muka whatu aratau-tahi (B1.3)
Ko te teitei o te wai iti-kore te dispersive displacement muka kotahi-aratau he pai mo te punaha tuku o te roopu katoa 1280nm ~ 1625nm, e kore e mau tonu te iti o te marara o te roopu tuku iho 1310nm, engari he iti te mate i te 1383nm, ka hangaia te roopu E. (1360nm ~ 1460nm) kua tino whakamahia.Ko te ngaronga me te marara o te roopu katoa mai i te 1260nm ki te 1625nm ka tino arotauhia, ka whakahekehia te ngaronga piko o te roangaru 1625nm, e whakarato ana i nga rauemi bandwidth mo te whatunga tuara, MAN me te whatunga uru.
