QSFP28/56  
and zQSFP+  
Interconnects  
TE Connectivity’s (TE) Quad Small Form-Factor Pluggable (QSFP28/56) and z-Quad Small Form-Factor Pluggable  
Plus (zQSFP+) interconnects offer increased data rates of 28 Gbps NRZ and 56 Gbps PAM-4 in an industry standard,  
scalable design that allows for backwards compatibility with QSFP+ cables and transceivers, providing a simple  
upgrade path from 10 Gbps to 28 Gbps and 56 Gbps. The complete portfolio of interconnects deliver a large range of  
simple and customizable design options to meet most customer requirements. TE’s zQSFP+ interconnects are dual  
sourced with Molex, LLC.

without heatsinks).  
Help increase assembly  
throughput by providing  
a 55% reduction in force  
needed to insert the line  
card into the front bezel.  
The reduction in insertion  
force makes assembly  
easier, faster, and reduces  
the risk for damage which  
can lead to reduced EMI  
performance.

these new cages  
provide 10 dB

current QSFP28  
products.  
plate area provides  
enhanced cooling to  
the lower ports and a  
12-15oC improvement  
over standard stacked  
zQSFP+ cages.  
Air vent holes allow for air  
to pass through and exit  
out the sides and rear of the  
cage.

Designed for Intel Omni-Path Architecture  
High Density  
Low Cost  
These QSFP28/56 and zQSFP+ 2x2 and 1x2  
cages are specifically designed for Intel Omni-  
Path Architecture (OPA) switch architectures,  
and 1x1 QSFP28/56 cages for OPA NIC cards.  
Designing with these cages allows access to  
proven technology to support high performance  
applications.  
Certain stacked cages can  
be used in belly-to-belly  
applications to support high  
density 2RU+ box designs and  
switch designs using next-gen  
48 and 64 silicon ports.  
Using a stacked belly-to-  
belly design enables single  
PCB architecture versus two  
PCBs per line card, saving  
significant system costs.

QSFP28/56 and zQSFP+ Interconnects  
Direct Attach Copper Cable Assemblies  
TE’s QSFP28 and QSFP56 passive copper cable assemblies  
feature eight differential copper pairs, providing four data  
transmission channels at speeds up to 28 Gbps NRZ and 56 Gbps  
PAM-4, and meet 100G Ethernet, 200G Ethernet and Infiniband  
Enhanced Data Rate (EDR) requirements.  
Offered in a broad range of wire gauges – from 32AWG up to  
26AWG – this 100G copper cable assembly features low insertion  
loss and low cross talk. This next generation cable assembly shares  
the same mating interface with QSFP+ and QSFP28 form factors,  
making it backward compatible with existing QSFP ports. QSFP28  
and QSFP56 form factors can be used with current 40G, 100G and  
200G applications with substantial signal integrity margin.  
Features and Benefits
