Buying Guide

Match form factor to your port

Confirm whether your switch or NIC accepts SFP or SFP+ modules; SFP+ modules are backward compatible with some devices but check vendor compatibility warnings

Choose the correct media type

Select copper (RJ‑45/10GBase‑T) for Cat6a/Cat7 in short runs and multimode or single‑mode fiber (SR/LR) for longer distances and lower latency

Check supported speeds and standards

Verify transceiver support for target speeds (1G vs 10G) and standards like 10GBase‑T, 10GBase‑SR, or 10GBase‑LR to ensure link negotiation succeeds

Consider reach and wavelength

Use multimode SR modules (850 nm) for shorter links up to a few hundred meters and single‑mode LR modules for longer runs over kilometers

Look for multi‑pack options for savings

Multi‑pack transceivers can reduce per‑unit cost when deploying several links and are common for compatible 10GBase‑LR or SR modules
