SFP-DD MSA issues two specs

The Small Form Factor Pluggable Double Density (SFP-DD) Multi-Source Agreement (MSA) Group has released updated 5.0 hardware specifications and drawings for the SFP-DD, SFP-DD112, and SFP112 pluggable modules. 

This revision enables SFP112 operating at 112 Gbps and SFP-DD112 operating at an aggregate rate of 224 Gbps; aligning with next generation higher speed networking, storage and access equipment. This new revision also includes an SFP112 module specification to ensure the industry roadmap from SFP28/SFP56 to SFP112 and SFP-DD to SFP-DD112 maintain overall compatibility.

SFP-DD MSA revision 5.0 hardware specification includes significant signal integrity enhancements to address 112 Gbps differential signaling. Three new clauses have been added as follows: Chapter 5 for SFP112 electrical and management interface requirements, Chapter 8 for SFP-DD 112G mechanical and board definition, and Chapter 9 for SFP112 mechanical and board definition. In addition, the new revision includes an ePPS/Clock signal definition for SFP-DD/SFP-DD112. Lastly, TS-1000 Normative Module and Connector performance requirements for SFP112 were added into Appendix A.

SFP-DD MSA promoters include Alibaba Group, Broadcom, Cisco, Dell Technologies, Hewlett Packard Enterprises, Huawei, II-VI Incorporated, Intel, Juniper Networks, Lumentum, Molex, Nvidia and TE Connectivity. Contributors include Accelink, Amphenol, AOI, Eoptolink, Foxconn Interconnect Technology, Fourte International, Genesis Connected Solutions, Hisense Broadband, Infinera, InnoLight, Maxim Integrated, Multilane, Nokia, Senko, Source Photonics, US Conec, Yamaichi Electronics, and ZTE.
