FTTH Mai karɓa na gani (CT-2001C)
Dubawa
Wannan samfurin shine mai karɓar gani na FTTH. Yana ɗaukar ƙaramin ƙarfin gani na gani da fasahar AGC mai sarrafa gani don saduwa da buƙatun fiber-to-the-gida. Yi amfani da shigarwar gani na wasa sau uku, sarrafa kwanciyar hankali ta siginar ta AGC, tare da WDM, 1100-1620nm CATV canjin siginar hoto da shirin fitarwa na USB na TV.
Samfurin yana da halaye na ƙaƙƙarfan tsari, shigarwa mai dacewa da ƙananan farashi. Yana da manufa samfur don gina USB TV FTTH cibiyar sadarwa.
