How it works
The G1001-MR G.hn to Ethernet Managed Demarcation Point devices power the Positron rugged IP67 (outdoor and extended temperature) GAM family with support for the ETSI Reverse Power Feed (RPF). Support for RPF facilitates the installation of the GAM outside of the MDU or MTU and in areas where it is not simple or cost effective to install a local power source. The GAM-8-MRX and GAM-4-MRX respectively have eight (8) and four (4) MIMO ports and can operate when powered from G1001-MR devices in SISO or MIMO mode.
The ITU-T G.9960 G.hn Wave-2 standard leverages the existing copper telephone wiring (UTP, CAT-3 or CAT-5/5e) as an access technology that delivers a Gigabit Internet service to each subscriber at a lower cost. This advantage avoids the delays that come with complex fiber installations for infrastructures.
Considered an access technology by Operators who need to simplify their backend infrastructure and access network with an Ethernet-like technology. This application is highly scalable without some of the inherent complexity of DSL-related technologies. Operators increasingly rely on G.hn to extend fiber or fixed wireless Gigabit services and avoid the high capital and operational expenses of a fiber retrofit. The Positron GAM solution is MEF CE 2.0 compliant and is ideally suited to deliver Business Ethernet services in an MDU and/or MTU deployment.
About the G1001 Managed Demarcation Point with RPF Support
When operating in a Reverse Power Feed mode, the outdoor GAM devices will always make sure that each G.hn End-Point devices it serves evenly contribute to provide power to the GAM via RPF. This means that the outdoor GAM will reject G.hn End-Point devices that do not provide their share of the power required by the GAM.

Now is the time for fiber operators to address the MDU challenge
In a new Broadband Communities article, Pierre Trudeau, President of Positron Access Solutions, explores one of the biggest opportunities facing fiber operators today: bringing Gigabit broadband to residents in existing MDUs without the cost and complexity of rewiring. The Positron GAM is the purpose-built multi-subscriber MDU ONT solution that makes this approach possible, leveraging the existing coaxial or telephone wiring to extend Gigabit connectivity to every resident.
