Abstract

In one embodiment, a module for plugging into a QSFP-DD (Quad Small Form Factor Pluggable Double Density) cage is provided that has one or more projections for contacting a QSFP-DD optical module in an adjacent QSFP-DD recess of the QSFP-DD cage so as to evacuate heat from, and or provide power to, the QSFP-DD optical module.
