Notes:
1. See SFF-8431 Rev 4.2 (SFP+) section D.15 Termination Mismatch for definition & test recommendations
2. Return Loss given by equation SDD11(dB)= -12.9 + 0.9·f, with f in GHz. See Figure 4
3. Common mode reference impedance is 25 . Differential to common mode conversion relates to generation of
EMI.

Notes:
1. Additional host margin to SFF-8431 rev 4.2. Provided to allow use of SFP+ adapters (P/N FTLX0071D4BNL).
2. Derived here by scaling the SFF-8431 rev4.2 spec of 0.023 by the relative increase in the non-data dependent
jitter over the SFF-8431 rev 4.2 spec: [(0.38-0.15) / (0.28 – 0.10)] * 0.023 UIrms.
