micro quad small form-factor pluggable (microQSFP) interconnects provide zQSFP+ (QSFP28) functionality in a smaller, generally SFP-sized form-factor. At 33% higher density than QSFP, microQSFP interconnects fit more ports (up to 72) on a standard line card, saving significant design space. The integrated module thermal solution on these products offers significantly better thermal performance than many other pluggable solutions on the market today, requiring less energy to cool equipment and allowing greater ease in system thermal design. These interconnects feature 56 Gbps (PAM-4) performance with backwards compatibility to 28 Gbps (NRZ) and future 56 Gbps (NRZ version will be backwards compatible). microQSFP has been adopted as MDI interface for IEEE 50G (1x), 100G (2x) and 200G (4x) links.
