Router TDT FG2000-W 4G Glasfaser-Router by TDT, model FG2000-W, 4G connectivity

The TDT FG2000-W is a 4G Glasfaser-Router designed by TDT to combine fiber network integration with cellular 4G connectivity. It supports primary or fallback WAN access via 4G while integrating into fiber-based broadband infrastructures, making it suitable for homes and small offices that require continued internet availability when fiber connectivity is interrupted or where cellular access is used as the main uplink.

Advantages

The router offers seamless switching between fiber and 4G WAN links to maintain internet access, and it supports standard routing functions needed in small network setups. Its design focuses on compatibility with fiber architectures while providing cellular connectivity for redundancy or primary access. The device is intended to be straightforward to install and manage in residential and small business environments.

Suitable for

• Homes requiring backup internet via 4G when fiber is unavailable.
• Small offices that need reliable connectivity with automatic failover to cellular networks.
• Installations where fiber is present but cellular access is used as a primary or secondary WAN link.

When it may not be suitable

The FG2000-W is intended for home and small office environments; it may not offer the advanced enterprise features, high port density, or throughput required in large corporate networks or data center environments. If you need carrier-grade routing features, large-scale VLAN segmentation, or very high concurrent session capacity, consider a product specifically built for enterprise deployments.

Key specifications

• Network connectivity: Fiber integration with 4G cellular WAN support for primary or fallback access.
• Use case: Residential and small office routing and internet failover.
• Functionality: Routing, WAN failover between fiber and 4G, basic local network management.
• Deployment: Wall- or desk-mounted consumer/SMB router form factor suitable for fiber-equipped locations.

How to use

Install the FG2000-W by connecting it to the fiber termination point for the primary WAN link and inserting a compatible 4G SIM card for cellular connectivity if required. Configure WAN preferences through the device’s management interface to set primary and fallback options, define local network parameters (LAN IP range, DHCP), and apply basic security settings such as admin password and firewall rules. Monitor connection status in the interface and verify that failover behavior meets your requirements by simulating fiber outages.

What to consider before purchase

• Confirm compatibility with your fiber termination and any required physical interfaces at the installation site.
• Check cellular network compatibility and SIM card/data plan requirements for 4G operation in your region.
• Assess whether the router’s feature set and performance meet your expected number of users and traffic patterns.

Usage recommendations

Use the FG2000-W as a primary fiber-connected router with 4G configured as automatic failover, or as a primary 4G WAN when fiber is not available. Maintain firmware updates and secure administrative access credentials to ensure stable operation and protect the local network.
