Overview :

  • GPT-2542GNUAC Gigabit-capable Passive Optical Network (GPON) Home Gateway Unit (HGU) Optical Network Unit (ONT) provides various integrated services through a single optical fiber for customers to support prevalent deployments of triple-play services such as data, video/High-definition Television (HDTV), VoIP and interactive games.
  • GPT-2542GNAUC features 802.11n and 802.11 ac technology to provide the ultimate solution for both speed and coverage. With 802.11ac wireless data rates of up to 1.3 Gbps, the GPT-2542GNAUC provides stable, reliable wireless connections for high-speed data and multimedia usages.
  • Advanced Quality of Service (QoS) ensures quality of triple-play services. Service providers can freely design their QoS policies and prioritize mission-critical services such as IPTV and VoIP based on their service plan offerings. This increases network efficiency and productivity that enable service providers to offer a real multi-play solution.
