All Rights Reserved. 10 Valuable attributes are provided by the unique construction Electrical Performance • High Bandwidth - resonance-free beyond 20 GHz • Excellent SCD21 & skew Thin and Foldable • Allows cable to be run through “non useable” space • Can be oriented to avoid blocking airflow, increasing cooling efficiency • Can be folded at very tight bend radii without SI degradation Improved Terminations • Ribbon construction fixes locations of signals and grounds • Efficient termination process with no wire routing errors • Ribbon construction minimizes termination variability for more reliable and repeatable processes ©11/9/2017 3M .

With the foldable cable construction, 3M Twin Axial Cable is able to make tight bends at the connector Illustrating the difference in space saving, a bundle of 80 - 30AWG SFP+ cables is compared – 3M Twin Axial Cable versus traditional round cable. For SFP+ and QSFP+ at the connector: • Minimum bend space up/down is 6mm • Minimum bend space left/right is 9mm 25% savings of cross-sectional space 3M 4x20 stack 1200 mm2 Traditional bundle 1605 mm2 SFP28 bend at connector: Small bend radius 3M™ QSFP+ Twin Axial Cable Assemblies have a smaller bend radius than traditional twin axial cable assemblies. When managing cables in the rack, this allows for efficient routing of cables with tight bends and folds to minimize obstructions to airflow and allow for better access to ports.
