3M™ Twin Axial Cable Assemblies
for PCI Express Applications
3M provides the latest in high-speed solutions to meet demanding system performance
and packaging challenges with the 3M PCI Express Extender Assemblies and PCI
Express Jumper Assemblies, for PCI Express 2.0 and 3.0.
We have incorporated our award winning 3M™ High-Routability Twin Axial Cable
into these assemblies that allow you to re-locate a PCIe card slot, or bridge between
slots on two different PCBs. The ribbonized format of the 3M cable provides a dense
and flexible solution, and these assemblies are available in X16, X8 and X4 standard
channel sizes. As with other 3M Twin Axial Cable, SL8800 Series, based products,
these assemblies can be folded to provide unique and specific geometries, maximizing
the use of space and reducing obstruction to airflow. These mechanical benefits are
provided along with the extremely low loss, and excellent signal integrity customers
have come to expect from 3M Twin Axial Cable, SL8800 Series.
Industry standard PCIe peripheral cards can be placed in virtually any orientation
within a system chassis. The 3M PCI Express Extender Assemblies can be folded
or simply routed to the peripheral card, providing a low loss extension from the
motherboard. Up to now, choices have been short assemblies, rigid PCB assemblies,
or high-loss flex circuit assemblies. Higher channel loss solutions may require the use
of PCI Express retimer chips. Another cost and design impact.
If your applications uses a mother board that needs to link to another PCB via PCIe,
and that PCB has PCIe connectors instead of edge fingers, then the PCIe Jumper
Assemblies may fit your need. All of the speed and flexibility of the original 3M
Extender Assemblies, but for card-to-card applications.
3M PCI Express Extender Assemblies are available in PCIe X4, x8 and X16 sizes,
utilizing PCIe standard motherboard interfaces. The boards have been designed
to minimize trace lengths. The connector PCB, on the Extender Assemblies, have
mounting holes, allowing it to be secured within a system.
Common applications for these assemblies are for flexible system packaging, airflow
optimization, or as extender cables for benchtop development. Rigid riser cards are
limited to a simple offset (up and over), while 3M PCI Express Extender Assemblies
can be configured to virtually any orientation within the cable length (up, over,
forward, backward, around, under, etc.). Similarly, the PCIe Jumper Assemblies
are equally flexible and can allow your separate PCBs to be placed in an optimal
configuration to meet your other packaging requirements. A single 3M assembly
may fit multiple mechanical designs.

3M™ Twin Axial Cable Assemblies for PCI Express
Another application is for systems where long PCB traces consume too much of the signal loss budget. Using
3M PCI Express Extender Assemblies or 3M PCIe Jumper Assemblies, customers may be able to eliminate
the requirement for re-timers when implementing long electrical lengths. Similarly, the assemblies can help to
avoid expensive low-loss laminate layers that may have been necessary to handle the PCI Express signals across
the required distance. Reducing layer count or avoiding high-performance laminates may contribute to system
design cost savings.
System density, performance enhancement and cost savings. Anything is possible.
PCI Express provides a powerful high bandwidth architecture for today’s microprocessor based systems.
Rather than let this high-speed architecture overload design budgets, offload the signals on to 3M PCI Express
Extender or Jumper Assemblies. Our standardized solution allows you to customize. And if these PCI Express
configurations do not meet your specific requirements, please contact your local 3M Sales Representative and
discuss the possibility of a fully customized solution.
3M PCI Express Assemblies are being installed into the latest Enterprise Computing equipment, by some of the
biggest names in the business. These assemblies are supporting PCI Express 2.0 and 3.0 applications. Call 3M
and let us help you get your signal integrity budget under control.
