Buying Guide

Match form factor to your port

Confirm your switch or NIC accepts SFP, SFP+, or RJ-45 modules to ensure physical and firmware compatibility

Choose the right medium

Pick copper (RJ-45/Cat6a) for short, cost-effective links and fiber (LC duplex) for longer runs and EMI immunity

Check wavelength and mode

Use multimode (850nm) transceivers for OM3/OM4 short-reach links and single-mode (1310nm/10km) for long-distance fiber

Consider speed and backward support

Select 10G SFP+ modules if you need 10 Gbps performance, or 1.25G SFP for Gigabit networks and legacy gear

Look for DDM/diagnostics

Modules with DDM/DOM report temperature and optical power, useful for troubleshooting and link health monitoring

Validate vendor compatibility

Confirm the module is known to work with your switch vendor or supports generic/third-party compatibility modes
