Positron G.hn Aggregation Multiplexer Product Family

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.

Introducing G.hn

The ITU-T G.9960 G.hn Wave-2 standard is designed to leverage the existing telephone wiring, (UTP, CAT-3 or CAT-5/5e) or RG-6/RG-59 coax cabling to deliver a Gigabit Internet service to each subscriber without the cost, complexity and delays associated with in-building fiber installation. G.hn is used as an Access technology by Operators looking to simplify their access network and backend infrastructure with an Ethernet-like technology that is highly scalable without some of the inherent complexity of DSL-related technologies. With G.hn, Operators deliver advanced services such as Gigabit High Speed Residential Internet and 4K IPTV without the high capital and operational expenses associated with a fiber retrofit. Each G.hn subscriber port supports up to 1.7 Gbps of dynamically allocated bandwidth for near symmetrical Gigabit services over the existing telephone wire or coaxial cable. The Positron GAM solution is MEF CE 2.0 compliant and is ideally suited to deliver Business Ethernet services in an MDU and/or MTU deployment.

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 (GAM)

The Positron GAM leverages a non-blocking CE 2.0 Carrier Ethernet Core ASIC to reliably deliver managed Gigabit services. The GAM is a Fiber to the Distribution Point (FTTDp) solution that is typically installed inside a wiring closet. Each GAM comes with two (2) 10 Gigabit SFP+ interfaces to support any type of fiber or PON standards (using an ONT as required). These SFP+ ports are also used to support additional GAM devices in medium to large MDUs and share the fiber backhaul link.

Positron G.hn to Ethernet Managed Demarcation Point CPEs

‘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 G1001 series of ‘G.hn to Ethernet’ Managed Demarcation Point devices complements the Positron G.hn Aggregation Multiplexer (GAM) family to deliver near symmetrical Gigabit Internet access to subscribers in MDUs over the existing telephone or coaxial infrastructure at a fraction of the cost of alternatives.

About the G1001 Managed Demarcation Point

The Positron G.hn to Ethernet Bridge (G1001-M for twisted pair, G1001-MP for twisted pair and POTS bypass or G1001-C for coaxial) is a Managed Demarcation Point that connects to a Residential Gateway (RG) that does not have native support for G.hn on its WAN port.

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

Positron G1001-MR and G1001-CR G.hn to Ethernet Managed End Point with RPF Support

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 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-CR devices. Each G1001-MR or G1001-CR powers a single G.hn port of the outdoor GAM devices.

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 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 links is protected 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.
