Black Box SFP (mini-GBIC) Module - For Data Networking - 1 RJ-45 1000Base-T Network LAN - Twisted Pair1.25 Gigabit Ethernet, Gigabit Ethernet - 1000Base-T - Hot-pluggable LFP443

10/100/1000 BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi-Source Agreement (MSA). They are 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).
