Positron G.hn MIMO Wave-2 to Ethernet Bridge over Twisted Pair with Reverse Power Feed

Positron G.hn MIMO Wave-2 to Ethernet Bridge over Twisted Pair with Reverse Power FeedFiber to the Home is far from the only and most efficient technology to deliver Gigabit Internet access to subscribers. Retrofitting an existing (brownfield) Multi Dwelling Unit (MDU) with fiber is complex and expensive.

Fiber to the Home is far from the only and most efficient technology to deliver Gigabit Internet access to subscribers. Retrofitting an existing (brownfield) Multi-Dwelling Unit (MDU) with fiber is complex and expensive. The Positron G.hn Aggregation Multiplexer (GAM) family delivers near symmetrical Gigabit Internet access to subscribers in MDUs over the existing telephone or coaxial infrastructure at a fraction of the cost of alternatives.

The Positron Access Solutions G1001-MR G.hn to Ethernet Managed Demarcation Point device powers 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 GAM-4-CXR has four (4) COAX ports and can operate when powered from G1001-MR devices. Each G1001-MR powers a single G.hn port of the outdoor GAM devices.

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.

The G1001-MR controls how a Residential Gateway (or User CPE) connects to the G.hn Access Network under the control of the Positron GAM. In this role, they make sure the information transmitted over the G.hn links is protected with strong AES-128 encryption.
