Comparing size of microQSFP (on left) to QSFP
Key Features
• Re-uses QSFP electrical pinout for ease of
adoption in networking systems
• 14.25mm port width enables up to 72 ports in
a traditional 1RU linecard while enabling
direct attach copper cables, optical
transceivers with MPO or LC functionality,
and active optical cables (AOCs).
• Integrated heatsink in module provides more
ecient thermal path for cooling active
optical and copper cables
• Cages allow for optimized airflow while
providing excellent EMI suppression
• Both side to side and front to back airflow
cages are available in stacked and
ganged configurations
• Cage solutions are designed to be belly to
belly compatible in both 1xN / 1xN and 2xN /
1xN configurations in a 4-6 layer PCB
Standards
The μQSFP (microQSFP) MSA references the
following protocol applications:
• 25G/100G Ethernet
• 100G InfiniBand EDR
• 32G/128G Fibre Channel
• 25G/50G Ethernet Consortium
• IEEE 50G (1x), 100G (2x) and 200G (4x) links

DATA AND DEVICES /// microQSFP INTERCONNECT SOLUTIONS
microQSFP Interconnect Solutions
28 and 56 Gbps Pluggable I/O & Cable Assemblies
Higher Density Design Saves Space for Increased Bandwidth
• 1x, 2x and 4x 28G and 56G solution provides QSFP28 functionality in a smaller,
generally SFP-sized form factor
• 33% higher density than QSFP to fit more ports (up to 72) on a standard line card,
saving significant design space
• 14.25mm port-to-port pitch
• Routable, 3-high belly-to-belly faceplate architecture with low cost PCB design
Increased Thermal Performance Saves Energy Cost
• Integrated module thermal solution oers significantly better thermal
performance than QSFP28 solutions
• Thermal performance does not suer in high density applications
• Thermal solution can be optimized based on power level design
• Ports provide additional equipment airflow, allowing for high port counts
in traditional line card designs
Standardized Form Factor Supports Next-Generation Designs
and Easy, Low Cost Implementation
• 56 Gbps (PAM-4) performance with backwards compatibility to 28 Gbps (NRZ)
• Future 56 Gbps (NRZ version will be backwards compatible)
• Enables total data center functionality and broad market adoption
• Multi-source agreement (MSA) has defined the mechanical features of the plug,
cage and receptacle to provide a standard interface with multiple connector, cable
assembly and fiber optic suppliers (visit www.microQSFP.com to learn more)
• Adopted as MDI interface for IEEE 50G (1x), 100G (2x) and 200G (4x) links
Product Applications
• Networking switches
• Routers
• Servers (blade, rack mountable and multi-node)
• Networking interface cards
• Optical transport equipment
