Product OVERVIEW

Netsys’ NHG-420M and NHG-200S are the latest technological innovation of G.hn wave 2 Ethernet over coaxial managed Master and Slave (client)respectively.

The NHG-420M Giga Ethernet over Coax Master connects with the NHG-200S MDU Slave, supporting both 10/100/1000Mbps Ethernet and coaxial cable connections for MDU and MTU applications. MDU and MTU typically have wired networks for small file transfers and shared applications. However, there is a growing need for high-speed applications like remote lecturing, telemedicine, IPTV, and fast internet access to support triple play services.

NHG-420M and NHG-200S are cost-effective solutions for MDU and MTU needs. With plug & play, this simply eliminates the pain in modification and high infrastructure cost. With data transmission up to 1.7Gbps and link establishment under -76db attenuation, it caters to the rising need for high-speed multimedia services. MDU and MTU applications enable high-bandwidth networking for buildings, apartments, hotels, resorts, sports centers, and similar locations.
