Cloudtron SFP-MRC-CU-100M 1000BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA). They are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std 802.3. The 1000BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.
The SFP-MRC-CU-100M uses the RX_LOS pin for link indication, and 1000BASE-X auto-negotiation should be disabled on the host system.
