The LFP443 is a Modular flexible optical transceiver for data communications equipment. This 10/100/1000 BASE-T Copper Small Form Pluggable (SFP) transceiver is based on the SFP Multi-Source Agreement (MSA). It is compatible with the Gigabit Ethernet standards as specified in IEEE Std 802.3. The 10/100/1000 BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features. 10/100/1000 BASE-T is compatible with 1000BASE-X auto-negotiation but does not have a link indication feature (RX_LOS is internally grounded).
