INTERCONNECT
SOLUTIONS
TE Connectivity (TE) is leading the industry in the design of
micro Quad Small Form-Factor Pluggable (microQSFP)
Connectors, providing a higher density solution for next
generation pluggable connectivity. With increasing
bandwidth requirements, demand is increasing for smaller
form factors that will oer increased faceplate density and
higher port count. These products need to maintain
superior thermal performance to keep energy costs low and
maximize reliability. The technological innovations of the
microQSFP form factor have the potential to revolutionize
the development of pluggable interconnect for next
generation designs.

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
ecient 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

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 oers significantly better thermal
performance than QSFP28 solutions
• Thermal performance does not suer 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
SOLUTIONS
FOR THE
DATA-DRIVEN WORLD
ENABLING THE MOVE TO HIGHER DENSITY
33% higher density than QSFP means you can fit more
ports (up to 72) on a standard line card, saving significant
design space.
ENABLING HIGH ELECTRICAL DENSITY BY SHIFTING THE THERMAL PARADIGM
An integrated module thermal solution oers significantly better thermal
performance than QSFP28 solutions and removes the largest source of thermal
resistance, ultimately requiring less energy to cool equipment and increasing the
ease of your system thermal design.
