They are compatible with the 10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T standards as specified in IEEE Std 802.3 . SFP+-10GBASE-T uses the SFP's RX_LOS(must be pulled up on host) pin for link indication. If pull up or open SFP's TX_DISABLE pin,  PHY IC be reset. • SFP to Host Connector Pin Out Pin Symbol Name/Description Ref. 1 VEET Transmitter Ground  (Common with Receiver Ground) 1 2 TFAULT Transmitter Fault.
