The RL841GWVC-AX3B terminal device is designed to meet the FTTH (Fiber to the Home) and triple-play service demands of fixed network operators or cable operators. Based on mature Gigabit GPON technology, it offers high cost-performance. The device supports multi-WAN connections in bridge or route mode, IPv4 and IPv6 protocol stacks, multicast protocols, QoS, firewall functions, Easy Mesh networking, and TR069 management protocols. It adopts the latest 802.11ax WiFi 6 technology standard (compatible with 802.11ac/b/g/n), supporting a 3000Mbps connection rate and high-quality VoIP services. With large transmission capacity, high speed, high reliability, and easy maintenance, it ensures QoS for various services and fully complies with technical regulations such as ITU-T G.984.x.
