Q: HOW IS QSFP-DD800 DIFFERENT THAN QSFP-DD? A: The QSFP-DD800 MSA is focused on the next generation of the QSFP family of modules. It will focus on increasing the aggregate module bandwidth and increasing individual line speeds to 112 Gb/s. In addition, changes are anticipated to the specification in the areas of thermal performance up […]
The QSFP-DD stands for a “Quad Small Form-factor Pluggable (QSFP) – Double Density (DD)”. The QSFP-DD connector also has 8 electrical lanes. The QSFP-DD form factor is similar to the QSFP form factor, except a second row of electrical contacts has been added to the QSFP connector in order to increase the number of high […]
The Quad Small Form Factor Pluggable Double Density (QSFP-DD) MSA Group (Multi Source Agreement Group) announced the release of an updated 4.0 Hardware specification for the QSFP-DD form factor at September 18, 2018. The latest hardware specification to address the industry need for an improved high-density, high-speed networking solution. Other notable features to the updated […]
SFP-DD is short for SFP Double Densty, it is a new module and cage/connector system similar to current SFP module, but with an additional row of contacts providing for a two lane electrical interface. It is being developed by the SFP-DD MSA as a key part of the industry’s effort to enable high-speed solutions. The […]
