1. What is an SFP copper transceiver used for?

It allows SFP ports on network devices to connect to copper Ethernet cables, enabling Gigabit communication over RJ45 interfaces.

2. Is this module compatible with all SFP ports?

It is compatible with most standard SFP slots, but some vendors may require coded or brand-specific versions.

3. What cable type is required for 100m transmission?

CAT5e or higher (CAT6/CAT6a recommended) is required to achieve stable 100-meter performance.

4. Does it support auto-negotiation?

Yes, it supports automatic negotiation for 10/100/1000Mbps speeds depending on connected devices.

5. Can it be used in switches and routers interchangeably?

Yes, it is compatible with most enterprise-grade switches and routers with SFP slots.

6. Does it generate more heat than optical SFP modules?

Copper SFP modules typically consume more power and generate slightly more heat than fiber SFPs, but remain within standard operating limits.
