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

Description

The Netsys NHG-420M G.hn 1000Base-T MDU Master and NHG-200S G.hn 1000Base-T MDU End Point (sold separately here) provide a cost-effective, high-speed G.hn Wave 2 Ethernet over Coax solution, specifically designed for Multi-Dwelling Units (MDU) and Multi-Tenant Units (MTU). Leveraging existing 75-ohm coaxial cable infrastructure (e.g., RG-59, RG-6), this solution enables up to 1.7Gbps aggregate data transmission speeds without the need for extensive rewiring. By utilizing coaxial cabling, which is already widely installed in apartments, hotels, office buildings, and other multi-unit properties, this system significantly reduces deployment costs while delivering fast, reliable, and long-distance connectivity.

The NHG-420M G.hn 1000Base-T MDU Master can connect with up to 15 NHG-200S G.hn 1000Base-T MDU End Points and handles attenuation levels up to -76dB, making it a scalable networking solution for high-density environments. The TV Port of the built-in splitter can be utilized to carry a TV or STB signal over the same 75-ohm coaxial cable (within the 250Mhz ~ 1.2Ghz transmission spectrum). This ensures that residents and guests can enjoy high-speed internet while maintaining access to services such as satellite or cable TV.

With plug-and-play installation for most applications, deployment is straightforward and efficient, making it easy to establish a high-speed network using existing coaxial infrastructure. The NHG-420M G.hn 1000Base-T MDU Master and NHG-200S G.hn 1000Base-T MDU End Point provide seamless connectivity even in high-bandwidth environments for internet, IPTV, telemedicine, remote learning, and other triple-play services, making them a future-proof, cost-efficient, and high-performance solution for MDUs, hotels, resorts, and other multi-tenant buildings.
