G.hn 1000Base-T Ethernet Over Coax MDU Master (1.7Gbps) - NHG-420M

Description

The Netsys NHG-420M G.hn 1000Base-T MDU Master is a high-performance Ethernet over Coax (EoC) networking solution built for Multi-Dwelling Units (MDUs) and Multi-Tenant Units (MTUs). Designed to operate with up to 15 NHG-200S G.hn 1000Base-T End Points (sold separately), this system delivers up to 1.7Gbps aggregate throughput using existing 75-ohm coaxial cables (RG-59, RG-6). It's the ideal solution for rapid, cost-effective network deployments in apartments, hotels, campuses, and office buildings—eliminating the need for expensive rewiring.

The NHG-420M Master supports up to 15 NHG-200S slave units, enabling scalable, long-distance networking in high-density environments. A built-in coaxial splitter with a dedicated TV port supports simultaneous transmission of RF signals for set-top boxes or televisions (within the 250Mhz ~ 1.2Ghz spectrum). New firmware now includes support for rate control configuration per connected slave unit, allowing network administrators to optimize bandwidth allocation through the intuitive web interface. This ensures optimal performance for various applications while maintaining service quality.

The NHG-420M Master supports connections to up to 15 NHG-200S End Points, enabling scalable coaxial networking in high-density environments such as MDUs, hotels, and multi-tenant commercial spaces. Its built-in coaxial splitter features a dedicated TV port that supports simultaneous RF signal transmission for televisions or set-top boxes (within the 250Mhz ~ 1.2Ghz spectrum), ensuring uninterrupted access to video services. Using the NHG-420M’s web interface, rate control can be set at 5M, 10M, 20M, 30M, 50, 75M, 100M, 200M, or full speed for each NHG-200S end point, allowing precise bandwidth management across the network while maintaining service quality.
