G.hn Access Multiplexer (GAM) with 4x Coaxial ports and 1x 10Gbps SFP+ port, Outdoor, RPF and 12VDC support

Delivering Gigabit to the Home

Positron GAM-4-MRX, GAM-8-MRX and GAM-4-CRX Rugged / Extended Temperature Reverse Power Fed GAM Devices

``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, highly disruptive and expensive. With the G.hn 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

The Positron G.hn Access Multiplexer (GAM) family now includes rugged versions for deployment in harsh environments (outdoor) where there is no local power source. These GAM devices obtain their power from the G1001-MR over the copper wiring or G1001-CR over the COAX cabling. The outdoor GAM devices offer the same feature and management capabilities as their indoor counterpart. They optimize coverage of Gigabit Internet services in an MDU and operate over twisted-pair cabling in Point-to-Point mode while operation over a coax infrastructure is in Point-to-Multipoint mode where each COAX port can serve up to sixteen (16) G1001-CR devices.

The GAM-4-MRX and GAM-8-MRX respectively have four (4) and eight (8) MIMO ports and support Reverse Power Feed (RPF) from G1001-MR devices, one per G.hn port. The GAM-4-CR has four (4) COAX ports and supports RPF mode from G1001-CR devices, one or more (in Point-to-Multipoint mode) per G.hn port.

The G1001-MR and G1001-CR (G.hn to Ethernet Managed Demarcation Point devices) power the Positron rugged IP67 (outdoor and Extended Temperature) GAM family with support for the ETSI RPF standard. Support for RPF facilitates the installation of the GAM outside of the MDU and in areas where it is not simple or cost effective to install a local power source. Each G.hn port of an outdoor GAM is powered from a G1001-MR (copper) or G1001-C (coax).

G.hn is a Proven Carrier-Grade Access Technology

G.hn is widely used by large Operators in multiple markets where it provides Gigabit services into MDU of all sizes as well as for residential neighborhoods. These Operators leverage the robustness of G.hn and its predictable bandwidth to scale to large deployments that complement their investment in their PON infrastructure. As is the case with other ITU DSL and PON standards, G.hn offers extensive management and troubleshooting features and capabilities to simplify its deployment, activation and support. These management capabilities cover all operational aspects, from dealing with wiring issues to service-aware QoS and bandwidth management. The G.hn ecosystem is very solid and includes verified interoperability between the three (3) main chipset vendors based on extensive testing by the University of New Hampshire (UNH) lab.

About the Positron G.hn Access Multiplexer and Reverse Power Feed Support

The G1001 devices control 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 link is secure with strong AES-128 encryption. When used in Point-to-Multipoint mode (coaxial wiring), the G1001-CR operates under control of the GAM to isolate the traffic from each subscriber that shares the same coax splitter.

NOTE: when there are multiple G1001-CR devices on the same GAM Coax port, each of the G1001-CR will share the power load evenly amongst them.
