This 10Gigabit SFP+ receiver is designed to receive optical data over single mode optical fibre for link length 40km. The SFP+ 40km module electrical interface is compliant to 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 reduce differential to common mode conversion for quality signal termination and low EMI. SFI typically operates over 200 mm of improved FR4 material or up to about 150mm of standard FR4 with one connector.     Absolute Maximum Rating These values represent the damage threshold of the module.  Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.

  • Module circuit ground is isolated from module chassis ground within the module.
  • Should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15Vand 3.6V.
  • Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ 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 > 30 kΩ resistors in the module.
