QSFP-DD Group releases Hardware and Common Mgt Interface Specs

The Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA) group released a hardware specification revision 6.0 updating QSFP-DD, introducing QSFP-DD800 and introducing QSFP112.

With the inclusion of support for 100 Gb/s electrical host interfaces, this 7th public release adds QSFP-DD800 and QSFP112 Mechanical and Board Definitions. It also adds QSFP112 electrical and management timing. Revision 6.0 includes updated power supply test methods and support for an increased module power rating to 25 W. The module power contact rating is increased from 1 A to 1.5 A. An appendix with normative connector performance data has also been added.


The group also announces the release of an updated Common Management Interface Specification (CMIS) revision 5.0 for QSFP-DD, QSFP-DD800 and QSFP112. The CMIS defines the host-to-module interactions needed to ensure that modules will initialize and operate consistently. This revision provides several extensions and a comprehensive technical and editorial consolidation. It is harmonized with timing parameters defined in QSFP-DD MSA HW Spec revision 5.1 previously published and in this revision 6.0. CMIS is broadly implemented across the industry, beyond just the QSFP/QSFP-DD family of module types. The feedback from many implementers has also been consolidated to improve and extend the specification.

“It is exciting to see how the 63 companies involved came together to harmonize these important QSFP/QSFP-DD form factors and software to future-proof data centers while maintaining backward compatibility,” said Scott Sommers, founding member, and MSA co-chair.

The MSA group also announces the release of a new thermal management whitepaper. High performance network environments need efficient cooling of pluggable optical modules. This is particularly true for the new high power 25 W modules for QSFP-DD800 systems, which must dissipate heat effectively to ensure operational performance. Careful thermal design of module, cage, heatsink, and the overall system for QSFP-DD modules is required for efficient heat dissipation. This new whitepaper explains techniques that can be used to achieve this goal in QSFP-DD/QSFP-DD800 module design and QSFP-DD/QSFP-DD800 system design. It includes both experimental and simulation studies to demonstrate the efficacy of these techniques.

“The performance and power demands for high-speed network solutions are constantly increasing,” said Mark Nowell, founding member, and MSA co-chair. “This whitepaper captures the design experience garnered over the recent years from many companies and was written to help design engineers understand how they can achieve the thermal characteristics their system requires, even when using new 25 W modules, thus ensuring the reliable operation of their products.”

Precision OT debuts QSFP-DD 400G transceivers

Precision OT introduced its new line of QSFP-DD 400G optical transceivers supporting distances between 100m and 10km.

Precision OT is offering 4 different transceiver variants for this form factor to ensure that network operators' varying needs can be fully met. Precision's QSFP-DD transceivers support the continued growth of network traffic while being backwards compatible with existing QSFP optics.

"Optical transceivers, especially 400G-capable ones, are the key component in enabling more traffic to flow across today's networks," says Chris Page, CTO of Precision OT. "Single lambda 100G will be one of the most cost-effective ways for MSOs and data centers to deal with future bandwidth demands, because a single 100G line can reduce the costs of a typical 4x25G architecture by at least 40%. In this way, the use of four lines of 100G and PAM4 modulation can enable the 400G data rates our customers need to ensure they are ready for the future. For us, at Precision OT, it is about creating networking solutions that grow over time and accommodate increased demand cost-effectively, with both flexibility and agility."

QSFP-DD800 MSA releases initial 800G transceiver spec

The Quad Small Form Factor Pluggable Double Density 800 (QSFP-DD800) Multi Source Agreement (MSA) group has released a new hardware specification for the QSFP-DD800 transceiver form factor.

The new QSFP-DD800 1.0 specification is intended to be incremental to the existing QSFP-DD 5.0 specification. As signal integrity and thermal performance remain imperative, the transceiver pads have been optimized to improve signal integrity for 100 Gbps performance per lane without affecting backwards compatibility. The new specification additionally defines a novel 2x1 connector/cage, with cabled upper ports as an option to address signal loss issues associated with tradition PCBs. Looking ahead, QSFP-DD800 promoters will continue to work on new connector/cage variants, including 2x1 SMT versions that operate at 100 Gbps per lane.

The MSA group was formed to advance the development of high-speed, double-density QSFP modules which support 800 Gbps connectivity and includes the following promoters: Broadcom, Cisco, II-VI, Intel, Juniper Networks, Marvell, Molex and Samtec.

“In the short time our group has collaborated, we are thrilled to introduce this first specification for the next generation of the QSFP family of modules,” said Scott Sommers, co-chair of the QSFP-DD800 MSA. “As signal integrity and thermal management remain challenges for the optical communications industry, our MSA group is confident that its solutions will meet performance needs.”

“With their superior system integration and design flexibility, QSFP modules continue to be the cornerstone in building next generation networks and network equipment, especially as port speeds increase to 800G,” said Mark Nowell, co-chair of the QSFP-DD800 MSA. “Furthermore, their ability to increase switch and routing bandwidth density without sacrificing backwards compatibility with QSFP-DD, QSFP56 and QSFP28 modules provide network operators tremendous commercial and operational advantages.”

QSFP-DD800 MSA gets underway

A new QSFP-DD800 Multi-Source Agreement (MSA) Group has been formed with the goal of advancing the development of high-speed, double-density quad small form factor pluggable (QSFP-DD800) modules to support 800 Gbps connectivity.

The MSA founder-promoters include Broadcom, Cisco, Finisar, Intel, Juniper Networks, Marvell, Molex and Samtec.

The new QSFP-DD800 interface expands on the QSFP-DD, a pluggable form factor with an eight-lane electrical interface widely adopted by the latest Ethernet switches. This MSA will enable QSFP-DD800’s eight electrical lanes to operate at 100 Gbps each, by providing technical solutions for 800 Gbps module and connector systems. It will also define a module, connector, stacked connector and a hybrid connector that is a BiPass/Flyover variant which can eliminate the signal losses on a traditional PCB. The primary objective of the MSA Group is to define the specifications and promote industry adoption of the QSFP-DD800. The new QSFP-DD800 specification is intended to be backward compatible with QSFP-DD, QSFP28 and QSFP+ modules and cables in order to address the upcoming industry demands of 25.6 Tb/s scale systems supporting dense 100 GbE or dense 400 GbE interfaces.

“Through continued strategic collaborations with our MSA Promoters, we are developing the physical specifications that will enable the interoperability of optical transceiver modules, connectors, cages and DAC cables from multiple vendors to assure a robust ecosystem,” said Scott Sommers, founding member and MSA co-chair. “We are thrilled to collaborate together as a group and further develop and provide next-generation designs that evolve with the changing technology landscape.’’

“Leveraging the technical innovations from QSFP-DD, the time is right to collaborate with our MSA partners to lay the foundations for the next generation systems and modules,” said Mark Nowell, founding member and MSA co-chair. “The QSFP-DD form factor continues to be the cornerstone for the next step in pluggable module performance and density, while extending the industry’s investment, experience, cost structure and backward compatibility from prior generations.”
