Cable System Supports 28G NRZ/56G PAM 4 Data Rates

Samtec’s Flyover QSFP28 cable system supports 28G NRZ/56G PAM 4 data rates per channel. The system allows sideband signaling via press-fit contacts to improve airflow, reduce loss, and mitigate skew. It can provide aggregate data rates of 100 Gb/s NRZ/200 Gbps PAM4, and is compatible with all MSA QSFP pluggables. A variety of heat sink options are available and allow a heat dissipation of approximately 3.5W per cable.


The system consists of the FQSFP assembly, QSFPC cage, HS-QSFP heat sink, and LP-FQSFP light pipe. The FQSFP offers multiple End 2 options including DCH, ECUE, and ARC6. FQSFP utilizes 30 & 34 AWG 100 Ω Eye Speed® Ultra Low Skew Twinax Cable. Samtec also offers an FQSFP SI Characterization Kit for evaluation and development.
