FAQ:

Q1: What is a Copper SFP module?

A1: Copper SFP (Small Form-factor Pluggable) is a hot-swappable transceiver that connects networking devices via RJ45 copper cables, supporting 10/100/1000Mbps Ethernet. It's widely used for short-distance data transmission in enterprise networks.

Q2: What's the maximum transmission distance of Copper SFP?

A2: Standard Copper SFP modules support up to 100 meters over Cat5e/Cat6 cables. For optimal performance, ensure proper cable quality and avoid electromagnetic interference.

Q3: Are Copper SFPs compatible with all switches?

A3: Most Copper SFPs follow MSA standards, but always verify compatibility with your switch brand. Some vendors require coded modules for full functionality.

Q4: How does Copper SFP differ from fiber SFP?

A4: Copper SFPs use RJ45 ports for electrical signals over copper cables, while fiber SFPs use optical connectors. Copper is cost-effective for short runs (<100m), whereas fiber excels in long-distance/high-noise environments.

Q5: How to troubleshoot high latency with Copper SFP?

A5: Check for cable damage/kinks

Test with shorter cable lengths

Verify duplex settings (auto-negotiation recommended)

Update switch firmware

Q6: What cable types are compatible with 1000BASE-T Copper SFP?‌

A6: Requires Category 5e/6/6a twisted-pair copper cables with RJ45 connectors. Maximum reach: 100 meters at 1Gbps.

Q7: Are 10G Copper SFP+ modules backward compatible with 1G switches?‌

A7: Yes, but requires:

Switch support for SFP+ form factor

Enable speed auto-negotiation in switch configuration.
