(iFDT is mainly used in FTTH-ODN network. iFDT (IntelligentFiberDistributionTerminal), namely the intelligent fiber optic cable transfer box, is one of the series products of Huawei's iODN solution. The uplink is connected to the trunk optical cable feeder segment (FeederCable), and the downlink is connected to the distribution optical cable segment (DistributionCable), which has the functions of fusion splicing, optical splitting and wiring of the traditional optical cable junction box. Through the interaction between the iField tool software and the U2000ODN management system, the intelligent optical fiber management and construction of the iODN is realized.)
