SFP+-10GBASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA). 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.
Features
● Support 10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T
● Hot-pluggable SFP footprint
● Compact RJ-45 connector assembly
● RoHS compliant and lead-free
● Single +3.3V power supply
● 10 Gigabit Ethernet over Cat 6a cable
● Ambient Operating temperature: 0°C to +65°C

SFP to Host Connector Pin Out
Notes:
1. Circuit ground is connected to chassis ground
2. PHY disabled on TDIS > 2.0V or open, enabled on TDIS < 0.8V
3. Should be pulled up with 4.7k - 10k Ohms on host board to a voltage between 2.0 V and 3.6 V. MOD_DEF (0) pulls line low to indicate module is plugged in.
4. LVTTL compatible with a maximum voltage of 2.5V.
