G.652D te muka whatu aratau-tahi (B1.3)

Whakaahuatanga Poto:

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.

Tono Hua

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.
