NDS3308T (V2) 8in1/16in1 DVB-T Modulator
Product Overview
NDS3308T (V2) 8in1 (or 16in1) DVB-T modulator is an all-in-one device developed by DEXIN. It supports maximum 512(or 1024) IP input through the 4 GE/SFP port and also 8 ASI input. After multiplexing 8(or 16) and DVB-T modulating, it gives 8(or 16) non-adjacent carriers (50MHz~960MHz), 2 ASI output and 8 or 16 IP (MPTS) output as mirror of carriers. The device is characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
Key Features
l 4 GE/SFP ports (max 512/1024 IP in):
Data1 is bi-directional port, max 512 IP in, 8 IP out(for 8 DVB-T out verison)
Data1 is bi-directional ports, max 1024 IP in, 16 IP out(for 16 DVB-T out verison)
Data2&3&4 ports only for input
