The AVM FRITZ!Box 5590 Fiber router is a tabletop router in white color, specifically designed for use with fiber-optic connections. It supports various fiber-optic technologies such as AON, GPON, and XGS-PON via SFP modules, with one AON and one GPON module included in the delivery scope. The device is suitable for use in private and small business environments where a stable and fast internet connection via fiber is required.

Applications
This router is primarily designed for operation with fiber-optic connections and enables direct use of bandwidth without additional media converters. It is suitable for use in apartments, small offices, or single-family homes where high network performance and comprehensive functionality for telephony, smart home, and network sharing are needed. The integrated DECT base supports up to six cordless phones and smart home devices, enabling it to function as a central control unit for intelligent home systems.

Functions and Features in Detail
The router features a 2.5-Gigabit WAN port (RJ-45) for fiber-optic connection, as well as four Gigabit LAN ports (RJ-45) for connecting computers, printers, or other network devices. Two USB 3.0 ports allow connection of external storage devices for use as a network storage (FRITZ!NAS) or for sharing printers over the network. The WLAN functions include dual-band operation at 2.4 GHz and 5 GHz, with maximum data rates of up to 2400 Mbit/s in the 5-GHz band and up to 1200 Mbit/s in the 2.4-GHz band, resulting in a total maximum WLAN data rate of 3600 Mbit/s. The router supports the Wi-Fi 6 (802.11ax) standard, as well as older standards such as 802.11a, 802.11g, 802.11n (Wi-Fi 4), and 802.11ac (Wi-Fi 5), ensuring broad compatibility with various end devices.

Technology Explained Simply
The 4x4 antenna configuration enables efficient use of WLAN bands, especially with many simultaneously connected devices. Support for MIMO (Multiple Input Multiple Output) improves signal quality and range, while MU-MIMO (Multi-User MIMO) can address multiple devices simultaneously, enhancing network performance in high device density. The network technology is based on IEEE 802.3bz and supports 10/100/1000Base-T(X) for LAN connections. The integrated firewall, NAT function, and dynamic DNS (DDNS) ensure secure and flexible network operation. The router also offers a DHCP server and UPnP support to simplify network configuration.

Compatibility and Accessories
The router comes with an integrated media server that enables sharing of media content within the network. The DECT base supports up to six cordless phones and smart home devices, serving as a central interface for telephony and smart home systems. The FRITZ!SFP modules for AON and GPON are included in the delivery, allowing the router to be directly connected to various fiber-optic connections. The use of WLAN mesh enables network expansion across multiple FRITZ! devices to ensure seamless coverage throughout the living area.

Installation and Mounting
The router is designed as a tabletop model and can be placed on a flat surface. Installation is guided by the included quick installation guide, which describes setting up the internet connection, WLAN, and telephony. The LAN, WAN, and USB ports are clearly labeled, and the integrated user interface (FRITZ!OS) allows intuitive configuration via a web browser. The delivery includes an AC power supply, an Ethernet cable, and a fiber cable to connect to the fiber-optic line.

Operational Advantages
The router offers high network stability and performance, especially when using fiber-optic connections. The integrated telephone system supports analog and DECT phones as well as IP telephony. Smart home functions allow control of intelligent devices such as power outlets, heating thermostats, or LED lamps. Security features such as firewall, guest access, and child protection safeguard the network against unauthorized access. Automatic updates ensure continuous firmware updates to close security gaps and provide new features. Energy-saving functions such as scheduled WLAN shutdown and Green Mode reduce power consumption when the device is not actively in use.
