Choosing the Right Cisco 10G SFP+: A Simple Comparison Guide

🟢 Standard Modules

These are full-featured and support everything (including FCoE, OTN, etc.).

• SFP-10G-SR: Short range (up to 400m on multimode fiber)
• SFP-10G-LR: Long range (up to 10km on single-mode fiber)
• SFP-10G-ER: Extended range (up to 40km)
• SFP-10G-ZR: Ultra-long range (up to 80km)

✅ Supports all protocols
✅ TAA compliant
✅ Good for enterprise/data center use

🔵 S-Class Modules (e.g., SFP-10G-SR-S, LR-S, ER-S, ZR-S)

These are cost-effective versions of standard modules.

• Same distance and fiber type as standard ones
• ❌ No FCoE support
• ❌ Not TAA compliant
• ✅ Cheaper

Use these if you don’t need advanced features like Fibre Channel over Ethernet.
