Samtec’s flyover QSFP28 cable assembly (FQSFP Series) achieves 28 Gbps performance and is backward compatible with all QSFP assemblies. This direct attach system, with press-fit tails that provide low speed signals and power to the PCB, allows drivers to be remotely located for design flexibility and greater control over thermal cooling.

Signal integrity is optimized by flying critical data over lossy PCB via Samtec’s ultra-low skew pair twinax cable with inherently lower attenuation. Re-timers are not required reducing cost and power consumption.
