What is QSFP high-speed differential cable?
Applications
Inside QSFP28 and QSFP56 optical modules, and in switch components where the run from the paddle card to the optical engine is only a few centimeters. The same short differential run shows up in 400G and 800G optics. The cable stays inside the module shell.
Key Benefits
Eight differential pairs keep each lane on its own impedance and hold crosstalk down in a very small space. The outer diameter has to fit the module, so the build stays thin. A shield can be added when pairs sit against each other inside the shell, or left off when the module does not need it. Impedance, skew, and wire gauge are set on the order. A QSFP jumper with plugs on it is quoted separately.
