DSFP / NGSFP Connectors
DSFP MSA has chosen Yamaichi’s proposal as leading design. Double data rate compared with SFP28 while being backwards compatible with SFP interfaces.
Advantages
- 2 x 112G/ch – same size as SFP but 2 channels
- Up to 200GbE per slot
- Double channel vs. single channel when compared to SFP
- 56Gbps NRZ and 112Gbps PAM-4 per diff. pair
- Same outer dimension as SFP
- SFP area size compatibility (same occupied area on the board)
- SFP mechanical parts compatibility (all custom-made mechanical parts can be used)
- MSA established
- High volume mass production
- Acc. to OIF CEI-112G-PAM4-VSR (latest draft)
