With growing network services such as HDTV, IPTV, voice-over-IP (VoIP) and multimedia broadband applications, the demand for bandwidth rises quickly. The current broadband environment has not reached its requirements. Rather, the FTTH (fiber-to-the-home) would be the most promising NGN (Next Generation Networking) application to fulfill the demand. PLANET Internet Fiber Router, FRT-40x series, provides office and residential users with the ideal solution for sharing a high-speed fiber Internet connection and four 10/100Mbps Fast Ethernet backbone. The FRT-40x series is a perfect FTTH Digital Home Router which can provide very high performance access to Internet, both downstream and upstream up to 100Mbps through the fiber interface. For the WAN connection, the FRT-40x series supports several common optical connectors including 100Base-BX, 100Base-LX, 100Base-FX and Small Form Factor Pluggable (SFP). The Fiber Router can be implemented easily for optical fiber deployment. The FRT-40x series provides QoS functions to enable smooth network services. Traffic priority can be assigned by the router to guarantee some important and specific transmissions, especially for real-time streaming multimedia applications such as the on-line gaming, VoIP, and IPTV to keep the bandwidth usage smoothly. Furthermore, the FRT-40x Fiber Router series not only provides basic router functions like DHCP server, Virtual Server, DMZ, and UPnP, but also features full firewall functions including Network Address Translation (NAT), IP / Port / MAC Filtering and Content Filtering. It serves as an Internet firewall to protect your network from being accessed by unauthorized users.
