SFP and SFP+ modules: what you need to know
These small modules determine the speed, distance and link type of your network. Here's how to approach them.
What does an SFP module do?
An SFP module plugs into a port on a switch or network device and defines the link type: fiber or copper, short or long range. SFP+ provides higher throughput.
Selection criteria
- Required speed (SFP or SFP+)
- Fiber type (multimode or single-mode) and distance
- Connector type
- Compatibility with the host equipment
Compatibility first
Some equipment only accepts specific modules. Checking compatibility before purchase avoids links that won't come up and deployment delays.
