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.

The reduction in insertion
force makes assembly

the risk for damage which
can lead to reduced EMI

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
•
Compatible with IEEE 802.3cd, IEEE 802.3bj, IEEE 802.3by and

•
•
•
Optimized construction to minimize insertion loss and cross talk
Customized 360° cable braid termination limits EMI radiation
Compatible with all existing QSFP connectors and cages
Pull-to-release slide latch design
32AWG up to 26AWG
Straight and breakout assembly configurations available
Customizable EEPROM mapping for cable signature
RoHS compliant
Low smoke zero halogen options available by request

Frequently Asked Questions
What data rates do QSFP28/56 and zQSFP+ support?
These products provide four data transmission channels at speeds up to 28 Gbps NRZ and 56 Gbps PAM-4 per channel.
Is TE’s footprint compatible with other suppliers?
TE’s 1xN QSFP28/56 cages are designed to SFF-8663 and are industry standard. TE’s zQSFP+ SMT connector and 2xN assemblies
are dual sourced with Molex, LLC.
Are heat sinks available?
Yes, TE offers a generous portfolio of heat sink heights and styles, as well as custom heat sinks upon request.
Is application tooling required?
Single port cage assemblies require only flat-rock tooling, while 1xN and stacked assemblies normally require specific application
tooling.
