The small form-factor pluggable (SFP) is a compact, hot-pluggable network interface module used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver in order to connect a fiber-optic cable or sometimes a copper cable.[1] The advantage of using SFPs compared to fixed interfaces (e.g. modular connectors in Ethernet switches) is that individual ports can be equipped with any suitable type of transceiver as needed.
 

Overview - Copper SFP Series:

The 10/100/1000BASE-T Copper SFP Transceiver is small form factor pluggable transceiver. They are compatible with SFF-8074i Multi- Sourcing Agreement (MSA) and comply with Gigabit Ethernet standard as specified in IEEE Std 802.3. They are compliant with RoHS and lead-free per Directive 2002/95/EC. The physical layer IC (PHY) can be accessed via I2C bus, allowing access to all PHY settings and features.

The 10/100/1000BASE-T Copper SFP Transceiver is SGMII interface copper SFP with 10/100/1000BASE-T auto-negotiation enabled default,support TX-Disable.
