CUDY 1.25G Multi Mode LC SFP Module

SFP-1000BASE-T/SFP-1000BASE-T-SGMII 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 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 1000BASE-T uses the SFP's RX_LOS pin for link indication. If SFP's TX_DISABLE pin, PHY IC be reset.
