1781EF - 4x Gigabit Ethernet, USB 2.0, Black/Silver
LANCOM 1781EF
High-performance VPN router with Gigabit Ethernet and additional SFP port for fiber connections
- Flexible business router with Gigabit WAN port for VDSL, cable or SHDSL modems;
- Energy-efficient Gigabit switch as per IEEE 802.3az as well as Gigabit SFP slot for fiber optics (FTTx);
- VPN site connectivity with 5 simultaneous IPsec VPN channels (25 channels optional);
- Network virtualization with up to 16 virtual networks on one device (ARF);
- Stateful-inspection firewall with intrusion detection/denial-of-service protection;
- High availability with optional 3G backup via USB.
The professional VPN router LANCOM 1781EF is the right choice for establishing modern company networks via fiber or copper lines. The flexible device has a WAN port and a small form-factor pluggable slot (SFP) for transceivers. With this, the LANCOM 1781EF can be deployed directly on fiber lines without additional hardware for WAN or LAN connectivity. Costs are reduced and all characteristics of the fiber line can be monitored from afar. With its extensive VPN capabilities and Gigabit Ethernet, the device provides secure, high-performance connectivity to branch offices and remote workers, and it supports a high-speed local network. The four ports of the integrated Gigabit Ethernet switch ensure maximum performance and are also energy-efficient as per IEEE 802.3az: If no data is transmitted over an interface, its power consumption shuts down automatically. The LANCOM 1781EF supplies everything required of a modern enterprise network, such as comprehensive Quality-of-Service capabilities and an object-oriented firewall.
