BM8723 Advanced QAM Modulator


The BM8723 is the latest generation mux-modulating all-in-one device. A single module supports up to 512 IP (MPTS/SPTS) input and 32 carriers output as well as 32 IP output after multiplexing (RF output for local transmission and IP output for remote sub-head end). It adopts the slot structure with one device supporting maximum 3 modules. Each module can work standalone. With its powerful performance and low cost, BM8723 is especially adequate for the new generation CATV system.
