The Unique
Advantages of GAM Copper for Outdoor Units

Leverages Outdoor Copper Wiring

Leverage current outdoor telephone and copper wiring for optimized coverage of Gigabit Internet services. Doesn’t Require costly retrofitting of fiber wires into your structure.

Deployable Anywhere

Deployable anywhere by being built with durability for outdoor use in harsh environments. Rugged IP67 enclosure and supports allows for operating an temperature of -40˚C to +65˚C.

Reverse Power Feeding

Reverse Power Fed into G1001-MR or G1001-CR End-Point devices for quicker and simpler deployment.

The Perfect Solution
For Outdoor Copper Infrastructure


The Positron GAM has is one of the best, most cost efficient solutions to increasing your gigabit needs.

Rugged and Extended Temperature GAM with Reverse Power Feeding

Fiber-to-Home is not the only and most efficient way to deliver Gigabit Internet access to subscribers. Retrofitting an existing (brownfield) Multi-Dwelling Unit (MDU) with fiber is complex and expensive. With the Aggregation Multiplexer (GAM), Positron Access addresses the key challenge of delivering Gigabit Internet access to subscribers in MDUs as well as dense Single Family Unit (SFU) homes by leveraging the existing telephone or coaxial infrastructure to deliver near symmetrical Gigabit services at a fraction of the cost of alternatives.

About the Rugged Outdoor Positron GAM Devices for Copper

The Positron Access Multiplexer (GAM) family now includes rugged versions for deployment in harsh outdoor environments where there is no local power source. These outdoor copper GAM devices obtain their power from the G1001-MR over the existing copper wiring.

When operating in a Reverse Power Feed mode, the outdoor GAM devices will always make sure that each End-Point devices it serves evenly contribute to provide power to the GAM via RPF. This means that the outdoor GAM will reject End-Point devices that do not provide their share of the power required by the GAM.

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 G1001-MR 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.

Deploying the GAM in an MDU / MTU

The GAM devices optimize coverage in an MDU / MTU over the existing wiring infrastructure. Since these GAM devices are Reverse Power Fed by the G1001-MR endpoint devices, they are deployable outdoors where they can withstand harsh environmental conditions.

The GAM devices are enclosed in a rugged IP67 enclosure and support operating temperature of -40˚C to +65˚C. While operation over twisted-pair wiring is always Point-to-Point, operation over a coaxial cabling infrastructure can be Point-to-Multipoint using standard coax splitters. In this mode, a 4-port GAM can serve up to 64 subscribers with up to 16 subscribers per port.

    Resources and CATV Coexistence – MDU Gigabit Speeds Without Compromise

    For carriers seeking to expedite their broadband deployment in underserved areas, the prospect of an in-building fiber installation for high-speed broadband is a daunting challenge. Fortunately, Positron’s Access Multiplexer (GAM) technology makes it possible to leverage a non-blocking CE 2.0 Carrier Ethernet Core to reliably deliver managed Gigabit services over existing infrastructure.

    Extending Gigabit Fiber services to Every Door without installing fiber to the door

    Positron’s Access Multiplexer (GAM) can extend your fiber services to every door of an MDU/MTU over the existing telephone pairs or coaxial cable to deliver Gigabit broadband. The Positron GAM delivers symmetrical Gigabit broadband without the need to install fiber to every door.

    Novus Shakes Up Canada’s MDU Broadband Market with Multi-Technology Approach

    Novus leverages Positron’s GAM to deliver high speed over older wiring. Novus is providing gigabit-speed services over Positron’s platform, and they have multiple buildings and 100 units in the field today using that technology.
