How to Choose the Right Cisco SFP Module
Choosing the correct module depends on your network requirements.
1. Distance
- 100m → Copper (GLC-T)
- 550m → MMF (GLC-SX-MMD)
- 10km+ → SMF (GLC-LH-SMD / SFP-10G-LR)
2. Speed
- 1G → SFP
- 10G → SFP+
3. Fiber Type
- Multimode (MMF) → Short distance
- Singlemode (SMF) → Long distance
4. Device Compatibility
Ensure the module matches your Cisco switch or router model.
