The Small Form Factor Pluggable Double Density (SFP-DD) Multi-Source Agreement (MSA) Group is pleased to announce its updated 4.1 hardware specification and drawings for the SFP-DD pluggable interface designed to enable high-speed 100+ Gbps, high-density networking equipment. The SFP-DD form factor uses 2-lane pluggable modules, is backward compatible with SFP+ and offers improved host to module management communication based on a Two-Wire-Interface (TWI).
SFP-DD revision 4.1 hardware specification includes added features to support ResetL, dual function IntL/TXFaultDD and ePPS. Newly added timing tables will also allow for low speeds signals, soft control and module status. The former chapter 7 Management Interface is now part of chapter 4, Electrical Specification. The updated hardware specification includes port mapping, optical connectors and module color coding moved out of Mechanical and Board Definition chapter 5 and into a new chapter 5. Lastly, TS-1000 Normative Module and Connector performance requirements were added as Appendix A.
New approach enables greater interoperability
Targeting support of optical modules up to 3.5 W, the SFP-DD form factor addresses the technical challenges of achieving a double-density interface and ensuring mechanical interoperability for module components produced by different manufacturers while still enabling the use of legacy SFP modules. This updated specification supersedes previous versions and has updated mechanical connector dimensions. Users should note that the connector dimensions specified in the 4.1 supersede all previous versions.
SFP-DD MSA promoters include Alibaba, Broadcom, Cisco, Dell EMC, HPE, Huawei, II-VI Incorporated, Intel, Juniper Networks, Lumentum, Molex, Nvidia and TE Connectivity. Contributors include Accelink, Amphenol, AOI, Eoptolink, FIT, Fourte, Genesis, Hisense, Infinera, Innolight, Maxim Integrated, Multilane, Nokia, Oclaro, Senko, Source Photonics, US Conec and ZTE.
