Positron MRX Outdoor 8-Port Twisted Pair MIMO G.hn Access Multiplexer with Reverse Power Feed

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.

• Reverse Power Feed: Complies with ETSI TS 101 548 v.2.2.1 in SR3 mode
• Power Source: Reverse Power Fed from G1001-MR or G1001-CR
