Product OVERVIEW
The NHG-300 is a Utilizing TDD (Time Division Duplexing) architecture and an expanded 100 MHz OFDM spectrum, the NHG-300 G.now modem leverages G.hn technology to revolutionize wireline broadband access as a superior upgrade to VDSL2. Delivering unmatched speeds of up to 1.7 Gbps over existing copper wiring, far surpassing the 100 Mbps limit of legacy VDSL systems, G.now is positioned to lead the 'last mile' of broadband services.
As a more cost-effective and agile alternative to FTTH, G.now allows telcos to provide high-performance access at competitive prices while maximizing their existing copper infrastructure. As a pioneer of the world's first G.now solution, Netsys reinforces its commitment to the evolution of broadband, supporting future-proof, bandwidthintensive applications such as UHD 4K Streaming.
