Risers Cards and Extender Cables

Sometimes system mechanical configurations force

add-in cards to be mounted in a different location

Riser cards and extender cables help with that

One PCI Express slot can also manage multiple PCI

Express cards



Internal 3M™ Cable Assemblies for PCI Express Applications with Flat Ribbon 3M™ Twin Axial Cable

• Supports Gen 1 - Gen 3 PCIe

• 85 ohm construction

• Target performance to support

PCIe Gen 4

• Space-saving, high-density design

• Folded 3D assemblies for advanced

packaging - custom

• Potential cost savings via FR4 and

re-driver elimination

• Other similar applications possible



3M™ Twin Axial Cable

• Thin

• Flat

• Flexible

• Foldable

• High-performance

• *Halogen-free

• Up to 25 Gbps

… and beyond



Highly-Consistent Construction

Consistent

Construction –

no pinching

Potential for uneven

construction, pinching

pressure

3M Benefits

Minimizes intrapair skew

(critical for 10 Gbps and higher speeds)

Minimizes insertion loss

Custom Applications

Using off the shelf components, OEM may feel pressure

to use existing chassis that may not fit application

environment

― Carts, cases, incorporation with other equipment modules

Custom design may then require specific designs,

forcing departure from economic benefits of off the shelf

― Pricing

― Manpower investments for design and manufacture

― Integration issues

New high performance flat foldable data cables bring

customization at off the shelf economies



Medical Imaging Cart

• Extension assembly from

main board PCIe connector

to graphics unit.

• Allows use of standardized

processing components

• And integration with custom

or off the shelf acquisition

components

• Alleviates some of the high

investment for customized

designs



Use of Flexible Cabling in Medical Electronics

Today’s electronics and processors require higher performance data cables

Bringing “flat and foldable” to high-performance cables once again opens up

possibilities

Allows customization using off-the-shelf components

― Customer driven packaging requirements (not component driven)

― Motherboards

― Acquisition cards

― Graphics cards

Allows modularity

Multi-purpose

― Cable can reach multiple positions depending on configuration

External Applications for Foldable Cable

Foldability of cable structure translates to rugged, kink-

insensitive external assemblies

Higher density of external wiring possible



3M™ Cable Assemblies for SFP+ Applications

Traditional SFP+ Cable Assembly

• Foldable

• High-performance

• Meets SFF-8431

requirements

• Able to support up

to 5 meters with 30

AWG

3M™ External MiniSAS Cable Assembly with Flat Ribbon 3M™ Twin Axial Cable

• SAS2.1, SFF-8088 compliant

• Small bend radius enables

flexibility

• Thin and low profile

• Excellent electrical

performance
