Advantages

  • Provides superior bandwidth to provide optimal high-speed internet experience.

  • Delivers Gigabit services to 2600 feet on RG-6.

  • Delivers Gigabit services to 1000 feet on RG-59.

  • Leverage your existing coaxial wiring and save on expensive fiber retrofitting costs.

  • Each G.hn subscriber port supports up to 1.7 Gbps of dynamically allocated bandwidth.

How it works

The Positron GAM 24C leverages the existing coaxial infrastructure to deliver high-speed gigabit performance over a distance of 2600 feet by using a non-blocking CE 2.0 Carrier Ethernet Core ASIC to reliably deliver managed Gigabit services. The GAM 24C is a fiber to the Distribution Point (FTTDp) solution. Each product comes with two 10 Gigabit SFP+ interfaces to support any type of fiber or PON standards (using an ONT as required). 

The ITU-T G.9960 G.hn Wave-2 standard is designed to leverage the existing RG-6/RG-59 coaxial cable to deliver a Gigabit Internet service to each subscriber without the complexity and delays associated with in-building fiber installation. G.hn is increasingly used as an Access Technology by Operators looking to simplify their access network and their backend infrastructure with an Ethernet-like technology that is highly scalable without some of the inherent complexity of DSL-related technologies.

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.

G.hn Delivers Superior Bandwidth

G.hn consistently delivers superior bandwidth over twisted pair wire and coaxial cable. G.hn dynamically adjusts the allocation of the bandwidth between the downstream and upstream direction to reflect the real-time traffic conditions for optimal and near-symmetrical performance under all conditions.

With the Positron GAM, high-speed Gigabit Internet Services are more stable, reducing support calls and customer churn. The GAM software extends its management capabilities to the G.hn end-point (aka G.hn to Ethernet Bridge) devices (such as the Positron G1001). The GAM hardware enforces per-subscriber bandwidth profiles and guarantees a fair and balanced use of the backhaul link at all times for value-added services such as IPTV, streaming and telephony. Its extensive support for VLAN (including Q-in-Q) allows for seamless integration with the operator fiber services and the OSS and BSS functions already in place. The service OAM capabilities of the GAM provide real-time information to the operator about the overall grade of services without any additional cost or complexity.

With hardware-assisted synchronization to improve the efficiency of Vectoring, the GAM optimizes the bandwidth for each subscriber based on the real-time condition.

The Positron GAM is available in 24 and 12 port configurations for either coaxial cable or twisted pair with support for 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.

Deploying the GAM in an MDU / MTU

The GAM is designed to optimize coverage in an MDU / MTU over the existing wiring infrastructure to avoid the high cost of installing new fiber inside these buildings. While operation over twisted-pair wiring is always Point-topoint, operation over a coaxial cabling infrastructure can be Point-to-Multipoint using standard coax splitters. In this mode, a 24-port GAM can serve up to 384 G.hn subscribers with up to 16 subscribers per port. The GAM terminates the links with a G.hn client device such as the Positron G1001-M or G1001-C managed end-points from Positron. Compliant Residential Gateways with built-in G.hn client support or with SFP ports are also fully supported.

The Positron GAM takes advantage of Positron’s SDN-ready VIRTUOSO software Domain Controller to control and manage GAM devices. VIRTUOSO presents a native management interface to the existing OSS and BSS systems of operators. VIRTUOSO can operate either as a standalone management plane server or under the control of standard-based Orchestration Platforms such as Open Daylight and others.

When interfacing with an ILEC/CLEC, the VIRTUOSO Domain Controller handles the management of the G.hn endnode served by a GAM. The OLT and Aggregation Router transparently handle Internet traffic with a single or double VLAN tag per subscriber.
