SFP+ PLUGGABLE
I/O INTERCONNECT
TE Connectivity’s (TE) family of SFP+ interconnects is designed to transfer data at speeds of up to 16
Gb/s. The portfolio features 20-position SMT connectors as well as cages in multiple configurations, and
with elastomeric gasket or enhanced EMI springs to address EMI containment at higher data rates. The
SFP+ interconnect family also includes thermal- and EMI-enhanced stacked configurations to further
improve performance.
Complementary SFP+ direct-attach copper cable assemblies are also oered by TE as high-speed,
cost-eective alternatives to fiber optic cables. The assemblies enable hardware OEMs and data
center operators to achieve high port density and configurability at low costs and with reduced power
requirements.

Thermal Enhancements
SFP+ stacked cages have been modified
to enhance thermal performance. These
changes include revised side walls of the
cage for airflow through the middle of the
cage to promote cooling of lower ports
Additionally, two thermal vent holes have
been added to each port to further enhance
thermal performance.
EMI Enhancements
SFP+ stacked cages with EMI
enhancements feature a gasket retention
plate with multiple attachment points
that improve the electrical connection to
the cage. A new right-angle design of the
gasket retention plate also improves the
strength of the product.
A pocket spring has been added to the
latch plate area to further reduce EMI
emission. This component is internal to the
cage assembly. The additional component
still allows airflow through the front of the
cage assembly.

Frequently Asked Questions
What is belly-to-belly mounting?
• Belly-to-belly mounting allows a customer to install
connectors and cages on both sides of a PCB. This
design reduces board space and is an alternative
solution to stacked connectors.
If I am currently using SFP cabling, can I use SFP+
host board configurations?
• Yes. SFP+ configurations support higher rates. You
can design SFP+ products in the host board for future
upgrades.
What data rate does SFP support?
• SFP supports up to 16Gb/s.
What are the PCB termination options?
• Cages are oered in press-fit and solder PCB termination
styles.
Is TE’s footprint compatible with other suppliers?
• It depends. The single port cages are designed to
industry standards. The ganged versions are not
compatible with all other sources.
Are heat sinks available?
• Yes. Riding heat sink technology is available for thermal
management.
Is application tooling required?
• Single port assemblies do not require application tooling,
yet ganged assemblies do require application tooling.
