The GAM is designed to optimize coverage in an MDU / MTU over the existing wiring infrastructure to avoid the high cost of installing new fiber inside these buildings. When using a GAM-24-C, it is possible to serve up to 384 G.hn subscribers over a coaxial infrastructure. This is achieved since G.hn natively operates in point-to-multipoint mode with standard coax splitters (up to 1:16 per port). The GAM terminates the links with a G.hn client device such as the Positron G1000-M or G1000-C managed end-points from Positron. Compliant Residential Gateways with built-in G.hn client support or with SFP ports are also fully supported.
The Positron GAM-24-C for Coax can deliver Gigabit services to 2600 feet (800 meters) on RG-6 and to 1000 feet (300 meters) on RG-59!
The ITU-T G.9960 G.hn Wave-2 standard is designed to leverage the existing RG-6/RG-59 coaxial cable to deliver a Gigabit Internet service to each subscriber without the complexity and delays associated with in-building fiber installation. G.hn is increasingly used as an Access Technology by Operators looking to simplify their access network and their backend infrastructure with an Ethernet-like technology that is highly scalable without some of the inherent complexity of DSL-related technologies.
With G.hn, Operators deliver advanced services such as Gigabit High Speed Residential Internet and 4K IPTV without the high capital cost of a fiber retrofit. Each G.hn subscriber port supports up to 1.7 Gbps of dynamically allocated bandwidth for near symmetrical Gigabit services over the existing coaxial cable. The Positron GAM solution is MEF CE 2.0 compliant and is ideally suited to deliver Business Ethernet services in MDU and/or MTU deployments.
