Notes:

Measured with conformance test signal for BER = 10–12. The stressed sensitivity values in the table are for system level BER measurements which include the effects of CDR circuits. It is recommended that at least 0.4 dB additional margin be allocated if component level measurements are made without the effects of CDR circuits.

Notes:

  • 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.
