QSFP-DD
QSFP-DD is a new module and cage/connector system similar to current QSFP, but with an additional row of contacts providing for an eight lane electrical interface. It is being developed by the QSFP-DD
Air Cooling and Water Cooling for Data Center High-Speed I/O
Quad Small Form-factor Pluggable-Double Density (QSFP-DD) high-speed I/O interconnect system is the smallest form factor being able to support ultra-high data s
QSFP-DD Connectors | High Speed I/O | Amphenol
The QSFP-DD family supports legacy QSFP channels on the front interface and four additional channels on the rear interface. This interconnect system optimizes density and power
