G.652D Fiber indhaha ee hal-habka ah (B1.3)
1. Ku habboon dhammaan noocyada qaab dhismeedka fiilada fiber optic: nooca tube beam dhexe, lakabka gacanta dabacsan nooca xayiran, nooca qalfoofka, qaab-dhismeedka fiilada fiber optic;
2. Codsiyada fiber indhaha waxaa ka mid ah: nidaamyada fiber indhaha u baahan khasaare hoose iyo bandwidth sare, sida isgaarsiinta fogfog, khadadka jirridda, feederayaasha loop, khadadka qaybinta iyo cable TV, iwm, gaar ahaan ku haboon 1383nm band qalafsan kala dhufashada kala qaybinta hirarka dhererka. CWDM), multiplexing qaybinta mowjadda cufan (DWDM) iyo isticmaalka deegaan gaar ah oo kala duwan (tusaale, Hillaac-caddayn OPGW cable indhaha, ADSS cable indhaha, iwm), fiber indhaha iyada oo qalab daahan iftiin gaar ah iyo habka daahan iyo ka dib processing, si waxay leedahay wax qabad aad u sarreeya oo ku saabsan sifooyinka farsamada iyo heerkulka sare ee waxqabadka deegaanka.
