3M SlimLine Twin Axial Cable Assemblies (SFF-8654)

The 3M™ SlimLine Twin Axial Cable Assemblies (SFF-8654) are ideal for PCIe (85 ohm) applications. The cable assemblies utilize 3M’s ultra-low profile, high speed, high signal density 3M™ Twin Axial Cable SL8800 Series. The new SlimLine cable assemblies are ideal for space constrained systems since the unique cable ribbon construction enables folding and bending without adversely impacting performance. The ribbon's foldability provides more freedom to design cable assemblies optimized to maximize system density, streamline system assembly and enhance airflow. Moreover, its low-profile enables assemblies to be routed through narrow openings between server components (such as fans, memory modules or heatsinks). The high-performance twinax cable construction provides excellent transmission properties, enabling a designer to effectively create PCIe connections inside a chassis.

Video

This TTI Tech Specs video for 3M™ SlimLine Twin Axial Cable Assemblies (SFF-8654) explains that folding or bending the cable doesn’t compromise signal integrity and has minimal impact on impedance, no more than one or two ohms per fold, and it’s available in 85 ohms for PCIe and 100 ohms for SAS applications, and more.

“Bend it, fold it, turn it.” That’s what 3M says about their SlimLine Twin Axial cable assemblies. When you need to fit high speed data in tight spaces and over long routes, this is the cable you need. Folding or bending the cable doesn’t compromise signal integrity and has minimal impact on impedance, no more than one or two ohms per fold, and it’s available in 85 ohms for PCIe and 100 ohms for SAS applications.

The cable uses 30 or 31 AWG wire sizes, offering an extremely low profile for routing between server components. Combined with its foldability, the 3M SlimLine Twin Axial cable assemblies allow for optimal airflow and maximum system density. Cable assemblies are available in x4 or x8 configurations, with and without sidebands, and with SFF-8654 straight or right-angle connectors.
