Official Specs: ER-X vs ER-X-SFP

What Is the EdgeRouter X?

The EdgeRouter X, also known as ER-X, is a compact Ubiquiti EdgeMAX router designed for affordable Gigabit routing. It is commonly used by small businesses, home offices, IT installers, and home lab users who want more control than a standard consumer router.

It is a good fit for:

• Small business routing
• Office internet management
• VLAN segmentation
• Firewall rules
• VPN setup
• NAT and DHCP control
• Guest network separation
• Home lab networking
• Basic traffic management

The biggest advantage of the EdgeRouter X is value. It gives users EdgeOS, Gigabit connectivity, and advanced network control in a small, budget-friendly router.

If your network does not need a fiber uplink or direct SFP connection, the ER-X is often the practical choice.

What Is the EdgeRouter X SFP?

The EdgeRouter X SFP, also known as ER-X-SFP, is the more flexible version of the EdgeRouter X. It includes five Gigabit RJ45 ports plus one 1G SFP port, making it better for networks that need fiber connectivity.

It is a good fit for:

• Fiber internet connections
• Fiber uplink router setups
• Small business networks with PoE needs
• Wireless ISP deployments
• Outdoor wireless backhaul
• Ubiquiti access point environments
• Multi-building network connections
• Cleaner router-to-switch uplinks

The SFP port is the main reason to choose this model. If your internet provider, switch, or network backbone uses fiber, the ER-X-SFP can help simplify the setup and reduce the need for extra conversion hardware.

Does EdgeRouter X Have an SFP Port?

No, the EdgeRouter X does not have an SFP port. It uses Gigabit RJ45 Ethernet interfaces only.

If you need direct fiber uplink support, choose the EdgeRouter X SFP instead. This is especially important for businesses using fiber handoffs, fiber switches, longer network runs, or setups where copper Ethernet is not the best option.

Is EdgeRouter X SFP Worth It in 2026?

EdgeRouter X SFP is worth it if your network needs fiber, an SFP uplink, or passive PoE output. It gives you more deployment flexibility than the standard EdgeRouter X.

It is not automatically the better choice for every buyer. If your network only needs copper Ethernet routing, the regular EdgeRouter X can still be the more practical option if reliable stock is available.

The main reason to pay more for ER-X-SFP is not speed. It is cleaner connectivity, fewer extra adapters, and better support for fiber or passive PoE layouts.

Who Should Buy Which Router?

EdgeRouter X vs EdgeRouter X SFP for Small Business

For small businesses, the right choice depends on how the network is built.

The EdgeRouter X works well for small offices that need:

A small agency, retail shop, clinic, or local service business may choose the EdgeRouter X for cost-effective routing. A warehouse, IT office, installer, or multi-building site may choose the EdgeRouter X SFP for fiber and PoE flexibility.

EdgeRouter X vs EdgeRouter X SFP for Fiber Uplink

If fiber is part of your network, the EdgeRouter X SFP is the stronger choice.

A fiber uplink router gives you cleaner options when connecting to a fiber switch, ISP handoff, outdoor wireless link, or another network area. Without an SFP port, the standard EdgeRouter X may require extra hardware to connect into a fiber-based setup.

That does not make the EdgeRouter X a bad router. It simply means it is built for standard Ethernet routing, not direct SFP connectivity.

Choose EdgeRouter X SFP if your setup includes:

• Fiber internet handoff
• Fiber switch uplink
• Outdoor wireless backhaul
• Multi-building connection
• Long-distance network run
• Router-to-switch fiber link

EdgeRouter X vs EdgeRouter X SFP for PoE Devices

PoE is another major difference between these two routers.

The EdgeRouter X supports 24V passive PoE input and PoE passthrough. This can be useful in simple setups, but it is more limited.

The EdgeRouter X SFP supports 24V passive PoE output across five RJ45 ports, which gives more flexibility when powering compatible devices.

This matters if you are working with:

• Compatible Ubiquiti access points
• Outdoor wireless devices
• Wireless bridges
• Small office network devices
• Passive PoE equipment

Important note: Passive PoE is not the same as standard 802.3af or 802.3at PoE. Always check device compatibility before connecting powered equipment. Using the wrong PoE type can create setup issues or damage hardware.

EdgeOS: Why Both Routers Are Popular

Both routers run EdgeOS, which is one reason they remain popular with technical users and small business networks.

EdgeOS gives users control over:

• VLANs
• VPNs
• Firewall rules
• Static routing
• NAT
• DHCP
• QoS
• Traffic management
• Policy-based routing
• Network segmentation

This makes both routers more advanced than typical consumer routers. They are good choices for users who want real network control instead of a basic plug-and-play device.

The tradeoff is that EdgeOS may require some networking knowledge. If you want full control, that is a benefit. If you want something extremely simple, you may need help with setup.

EdgeRouter X vs EdgeRouter X SFP Performance

According to Ubiquiti’s datasheet, both models are rated at 260 kpps for 64-byte packets and 1 Gbps for 1518-byte packets.

The main difference is not raw performance. It is:

• SFP connectivity
• Fiber uplink support
• Passive PoE output
• Deployment flexibility
• Cleaner expansion options

For basic routing, VLANs, firewall rules, and small business networks, both models can work well when configured properly.

If your network needs heavier routing, advanced QoS, deep packet inspection, or larger workloads, consider a higher-end EdgeRouter instead.

Are EdgeRouter X and EdgeRouter X SFP Still Available in 2026?

Both EdgeRouter X and EdgeRouter X SFP may be difficult to source through official retail channels in 2026, so buyers should always check current stock before planning a deployment.

That does not make the comparison irrelevant. Many buyers still compare ER-X vs ER-X-SFP when checking reseller stock, refurbished units, replacement routers, or remaining supplier inventory.

If both models are available, choose based on your network needs. EdgeRouter X is the better fit for lower-cost Ethernet routing, while EdgeRouter X SFP is the better choice if you need an SFP port, fiber uplink support, or 24V passive PoE output for compatible devices.
