PRODUCT DESCRIPTION
SFP-100BASE-Tx Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the 10base-T / 100base-Tx standards as specified in IEEE Std 802.3 . SFP-100BASE-T uses the SFP's RX_LOS pin for link indication. If pull up SFP's TX_DISABLE pin, SWITCH IC be reset.
