SFP-DD MSA Releases High-Speed, High-Density Interface Specification v2.0

Two-lane 3.5 W electrical interface enables high-speed enterprise networking Transceiver form factor doubles bandwidth and supports fast line rates Backwards compatibility with existing SFP interfaces and new SFP-DD styles Rome, Italy – September 17, 2018 – The Small Form Factor Pluggable Double Density (SFP-DD) Multi Source Agreement (MSA) Group announces the release of the v2.0 specification for the SFP-DD pluggable interface. Dedicated to fostering the development of next-generation SFP form factors used in DAC and AOC cabling, and optical transceivers, the MSA consortium released the initial SFP-DD specification version 1.0 in September 2017 and earlier this year released version 1.1. The newly updated specification version 2.0 reflects enhancements to the mechanicals, extended modules and enhanced polarizing key of the high-speed, high-density SFP-DD electrical interface, targeting support of up to 3.5 W optical modules in an enterprise environment. 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. The innovative electrical interface is designed to support two lanes that operate up to 25 Gbps NRZ or 56 Gbps PAM4 per lane modulation — providing aggregate bandwidth of 50 Gbps NRZ or 112 Gbps PAM4 with excellent signal integrity. ‘’Through strategic collaborations we work to increase speed, density and scalability in next-generation servers,” said Scott Sommers, Chair of the SFP-DD MSA. “We effectively enhance the roadmap in network applications to meet the challenging demands data centers and enterprise networking platforms are up against.” It is anticipated that many MSA members will be demonstrating SFP-DD at the upcoming European Conference on Optical Communication, Sept 23rd-27th in Rome, Italy. SFP-DD MSA founding members include Alibaba, Broadcom, Cisco, Dell EMC, Finisar, Hewlett Packard Enterprise, Huawei, Intel, Juniper Networks, Lumentum, Mellanox Technologies, Molex, and TE Connectivity. Contributing members are Accelink, Amphenol, AOI,

SFP-DD MSA Releases High-Speed, High-Density Interface Specification v1.1

Two-lane 3.5 W electrical interface enables high-speed enterprise networking Transceiver form factor doubles bandwidth and supports fast line rates Backwards compatibility with existing SFP interfaces and new SFP-DD styles Chicago, IL – January 26, 2018 – The Small Form Factor Pluggable Double Density (SFP-DD) Multi Source Agreement (MSA) Group is pleased to announce the release of an updated specification for the SFP-DD pluggable interface. Dedicated to fostering the development of next-generation SFP form factors used in DAC and AOC cabling, and optical transceivers, the MSA consortium released the initial SFP-DD specification (version 1.0) in September 2017. The updated specification (version 1.1) reflects enhancements to the mechanicals and drawings of the high-speed, high-density SFP-DD electrical interface comprising a module and cage/connector system targeting support up to 3.5 W optical modules in an enterprise environment. 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. The innovative electrical interface is designed to support two lanes that operate up to 25 Gbps NRZ or 56 Gbps PAM4 per lane modulation—providing aggregate bandwidth of 50 Gbps NRZ or 112 Gbps PAM4 with excellent signal integrity. In combination, an SFP-DD server port and QSFP-DD switch ports can effectively double port density in network applications. The SFP-DD interface helps meet increased demand for port density and scalability in next-generation servers. Extending speed and density, the SFP-DD electrical interface expands on the existing SFP pluggable form factor, a widely adopted interface used in data centers and other networking platforms. A key guiding principle of the MSA 1.1 specification is backward compatibility. The SFP-DD port is backwards compatible with legacy SFP and SFP+ style cables, modules and AOCs, and all new SFP-DD electrical interfaces. SFP-DD MSA founding members include Alibaba, Broadcom, Cisco, Dell EMC,

SFP-DD MSA Releases Specification for High-Speed, High-Density Interface

 New SFP-DD pluggable form factor features additional 2 rows of electrical contacts  Doubles the lane density and data speed in next-generation networking equipment  Cage/connector system backward compatible to SFP electrical interfaces Gothenburg, Sweden – September 18, 2017 – The Small Form Factor Pluggable Double Density (SFP-DD) Multi Source Agreement (MSA) Group recently completed the initial hardware specification and drawings for the SFP-DD pluggable interface designed to enable high-speed, high-density networking equipment. Targeting support up to 3.5 W optical modules in an enterprise environment, 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. The SFP-DD electrical interface expands on the existing SFP pluggable form factor, a widely adopted interface used in data centers and other networking platforms. The SFP single lane interface operates up to 28 Gbps NRZ or 56 Gbps PAM-4. The new SFP-DD electrical interface is designed to support two lanes that operate up to 25 Gbps NRZ or 56 Gbps PAM-4 per lane, providing aggregate bandwidth of 56 Gbps or 112 Gbps. By doubling the lane density and data speed, the SFP-DD interface will help address demand for increased port density and scalability in next-generation applications, with a primary focus on the server side interconnect. An SFP-DD server port along with QSFP-DD switch ports provides an overall doubling of the port density in network applications. The SFP-DD hardware specification and drawings define key module, plug, and cage characteristics. SFP-DD modules and direct-attach cable plugs use a common mechanical outline. Modules and plugs provide a means to self-lock with the cage upon insertion. Network equipment based on the SFP-DD will support legacy SFP modules and cables, and new double density products, for optimal design flexibility. SFP-DD Key Features  A single

SFP-DD MSA to Define Specification for New Small Form-Factor Pluggable Interface

Fourteen industry leaders join forces to double lane density and data speed of SFP transceivers Berlin, Germany – July 12, 2017 – The SFP-DD Multi-Source Agreement (MSA) Group has announced intent to develop the specification for a high-speed, double-density small form-factor pluggable (SFP-DD) interface. Under the MSA, participating companies will address the technical challenges of achieving a double-density SFP interface and ensuring mechanical interoperability for module components produced by different manufacturers. New SFP-DD based networking equipment will support legacy SFP modules and cables, as well as new double density products. The SFP-DD MSA founding members include Alibaba, Broadcom, Brocade, Cisco, Dell EMC, Finisar, Hewlett Packard Enterprise, Huawei, Intel, Juniper Networks, Lumentum, Mellanox Technologies, Molex, and TE Connectivity. Members of the MSA will develop operating parameters, signal transmission speed goals, and protocols for the SFP-DD interface, which expands on the SFP pluggable form factor, a widely adopted electrical interface used in data centers and other networking platforms. Multi-vendor SFP modules and assemblies are available today in a range of data rate speeds and reaches to support data transmission applications including hubs, switches, routers and servers. The SFP interface’s single electrical lane operates up to 25 Gbps NRZ or 56 Gbps PAM4.
