Best Routers with SFP Ports

An SFP cage takes a fiber module or a direct-attach cable, so the router can plug into some fiber lines or a 10G switch directly.

What an SFP port is for

SFP and SFP+ ports are rare on home routers, and the routers that have them are aimed at fiber and homelab setups. An SFP+ port gives a 10 Gbps link to a switch or fiber module without the heat of 10G copper.

Check whether the SFP port can act as WAN, LAN or both, and what speed it supports. See 10G routers for copper 10G options.

Frequently asked questions

What is an SFP port?

A slot that takes a small plug-in module: a fiber transceiver, a copper module or a direct-attach cable. SFP runs at 1 Gbps, SFP+ at 10 Gbps.

Can I plug my fiber line straight into an SFP port?

Sometimes, with the right module and your provider's approval. Most providers still want their own fiber box (ONT) in place.

Do I need SFP at home?

Mostly for homelabs and 10G networks: a direct-attach cable to a 10G switch is cheap, cool-running and reliable.
