This 10Gigabit SFP+ transceiver is designed to transmit and receive optical data over single-mode optical fiber for a link length of 10KM. The 10KM SFP+ module electrical interface is compliant with SFI electrical specifications. The transmitter input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled. The module provides differential termination and reduces differential to common mode conversion for quality signal termination and low EMI.

Notes:

The module circuit ground is isolated from the module chassis ground within the module.
Should be pulled up with 4.7k – 10k ohms on the host board to a voltage between 3.15Vand 3.6V.
Tx_Disable is an input contact with a 4.7kΩ to 10kΩ pullup to VccT inside the module.
Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ. Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.
RS0 and RS1 are module inputs and are pulled low to VeeT with > 30kΩ resistors in the module.
