3M SL8800

3M™ Twin Axial Cable
SL8800 Series
Your system should be built around performance, not
around your cables.
The 3M Internal Twin Axial Ribbon Cable SL8800 Series is a new ultra low-profile,
high-speed, high signal density cable. The products in the SL8800 Series are only the
first of a new family of high-performance cables from 3M.
No compromises
The SL8800 Series Cable is not just for densely packaged systems. The electrical
performance places this cable in an elite category for skew control, low attenuation
and high bandwidth. Even if your system does not require low-profile cable, the
SL8800 Series still provides you with a quality high performance cable for
your high-speed signal requirements.
SL8800 Cable Series is a longitudinally shielded cable construction and is made to
exacting tolerances. The cable suffers little to no resonance or “suck out,” where
traditionally spiral wrapped twin axial cables exhibit an enormous loss of signal at a
particular range of frequency. The cable is also low skew, and the ribbon construction
allows customers to further control any skew that can sometimes be introduced when
trying to manage individual channels. This is especially critical at speeds beyond
10 Gbps. High speed applications continue to demand more performance out of the
cables, and the SL8800 Series Cable will deliver that performance for years to come.
As signal speeds continue to increase, cable can improve but the termination can
still be a weak point. The SL8800 Series Cable standard ribbon format supports
high performance termination, repeatability, and a reduced possibility for pinout
error. When stripped in parallel, and then applied in parallel, each channel results
in an identical termination length. Control and placement of individual channels
is not required, eliminating the variation in performance and rework due to
incorrect placement.
3M™ Twin Axial Cable SL8800 Series is
longitudinally shielded and made to exacting
Attenuation - SDD12
Currently available in four-channel 100 ohm 30 AWG versions, the SL8800 Series
Cable is the optimum solution for space-constrained systems. This cable is unjacketed,
extremely thin, very flexible and can even be folded with minimal loss or performance
impact. Some high density offerings sacrifice performance to achieve density. For
example, flex circuits are often used for tight packaging requirements, but flex circuitry
can be cost prohibitive and can have limited bandwidth. SL8800 Series Cable can
route along the sides of cabinets and through narrow openings in densely packaged
equipment with little to no effect on performance.

3M™ Twin Axial Cable SL8800 Series exhibits low
loss and no “suckout.”
3M™ Twin Axial Cable SL8800 Series is flexible,
foldable and highly routable.
The 3M™ Twin Axial Cable SL8800 Series is ideally suited for paddle card terminated cable assemblies, such as mini serial attached
SCSI (miniSAS). The cable has been functionally tested in SAS 2.0 applications and passes those requirements in a 6 Gbps environment.
Depending on length and attenuation requirements, applications to 10 Gbps and beyond can be implemented with SL8800 Series Cable.
3M will support you and your system requirements as bandwidth demands increase. Look for future versions of 3M high speed cable in
other wire gauges, form factors and increased performance.
Cables should not be a design constraint. Make them a design enabler.
