The Positron GAM has 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. Gigabit solutions delivered over Fixed Wireless Access (FWA) are also supported by connecting the 1-10Gbps Ethernet feed into an SFP+ port of the GAM.
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 much more stable than G.fast. The GAM software extends its management capabilities to the G.hn end-point (aka G.hn to Ethernet Bridge) devices (such as the Positron G1000). The GAM hardware enforces per-subscriber bandwidth profiles and guarantees a predictable 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) complies with the Broadband Forum TR-101 specification allowing 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.
G.hn is used by large Operators in multiple markets with a strong base in South East Asia where it provides Gigabit services into MDU / MTU of all sizes and for residential clusters. These Operators leverage the robustness of G.hn and its predictable bandwidth to scale to large deployments that complement their investment in their Passive Optical Network (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.
The Positron GAM is available in 24 and 12 port configurations for either coaxial cable or twisted pairs 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.
