Ubiquoss GAM (G.hn Aggregated Multiplexer) U4124B product line-up is based on ITU-T G.hn G.9960/G.9961 technology that enables data rates up to 500Mbps over bundle copper cable(bundle phone line)and addresses Gigabit speed internet associated with FTTH(Fiber to the home) applications. Ubiquoss GAM U4124B 24 GE ports GAM with two G.now line-up. It is suitable for last mile of FTTDp (Fiber to the distribution point) solution and has an impressive Gigabit grade performance. 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 while avoiding the costs of replacing copper wires with fiber and truck-roll. These Gigabit speed data rates transmitted by U4124B ensure high quality services such as multi-stream FHD/UHD IPTV, cloud-based storage or 802.11ac WiFi AP.

The crosstalk in non-shielded bundle cable is solved by the Marvell Crosstalk mitigation feature, which guaranties 3-5times higher speed(200~500Mbps) than VDSL2 with same environment.
