With growing network services such as HDTV, IPTV, voice-over-IP (VoIP) and Multimedia broadband applications, the demand of bandwidth rises quickly. The current Broadband environment has not already accorded with needing; the FTTH (fiber-to-the-home) would be the most promising NGN (Next Generation Networking) application to fulfill the demand. The PLANET Internet Fiber Router, FRT-40x series, provides office and residential users 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 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 Fiber Router FRT-40x 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.
