“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.

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-toMultipoint 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).

With hardware-assisted synchronization to improve the efficiency of Vectoring, the GAM-4-MRX and GAM-8-MRX optimize the bandwidth for each subscriber based on the real-time condition. These GAM devices operate over twisted pair and support Single Input Single Output (SISO) mode, (1 pair per port) and Multiple Input Multiple Output (MIMO) mode (2 pairs per port). Using MIMO instead of DSL pair bonding means that there is no need to allocate two (2) ports to serve a single subscriber, lowering costs and avoiding the complexity of pair bonding.

Features:

• 8 port G.hn Access Multiplexer (GAM) for use over Twisted Pair wiring for 1 pair (SISO) or 2 pairs (MIMO) per G.hn port
• IP67-rated with extended temperature operation (-40°C to +65°C)
• Supports ETSI Reverse Power Feed (acting as a Powered Device - PD)
