Home Gateway GPON, 1xGE, 1xFE, 1xFXS

GPON home gateway for complete triple-play services

The FTTH GPON home gateway Innbox G31 is designed to deliver a full range of services: internet data, voice over IP (VoIP) and IP video, including bandwidth-consuming HDTV. The Innbox G31 provides two LAN Ethernet ports, one of which is gigabit, removing bandwith limitations for heavy networking applications. Additionally, one port for telephony services is provided using VoIP technology compatible with SIP environments.

The Innbox G31 home gateway is ideal for FTTH deployments where high-speed data must be transported reliably. The ONT also operates well in conjunction with separate devices such as routers and WiFi access points to provide even more flexibility with deployment. The Innbox G31 ONT with its small and stylish form-factor is manageable remotely and supports full-range FCAPS including supervision, monitoring and maintenance, as well as embedded NAT and firewall. delivering secure broadband access to all connected clients.
