Ubiquoss GAM (G.hn Aggregated Multiplexer) U4124B product line-up is based on ITU-T G.hn G.9960/G.9961 technology, enabling data rates up to 500Mbps over bundle twisted pair copper wires. It offers near FTTH (Fiber To The Home) performance for a wide range of applications. Ubiquoss GAM U4124B is configured with 24 GE ports with two Up Links. Intended for installation at a fiber to twisted pair distribution hub, it is easier to deploy and provides big CAPEX savings compared to FTTH.
Ubiquoss GAM U4124B enables carriers to deliver FTTH-class service to MDU:s while avoiding the costs of replacing copper wires with fiber and truck-roll. The data rates offered by the U4124B ensure unhindered throughput of high quality and other high data rate services such as multi-stream FHD/UHD IPTV, cloud-based storage or 802.11ac WiFi AP.
Crosstalk in bundles of non-shielded twisted pair lines is resolved by the Marvell Crosstalk mitigation feature, guaranteeing 3 to 5 times higher data throughput (200~500Mbps) than VDSL2 over the same final access lines. |
