A variety of heat sink options are available and allow a heat dissipation of approximately 3.5W per cable. The Samtec Flyover QSFP28 Cable System consists of the FQSFP assembly, the QSFPC cage, HS-QSFP heat sink, and LP-FQSFP light pipe.
The FQSFP offers multiple End 2 options including DCH, ECUE, and ARC6. FQSFP utilises 30 & 34 AWG 100 Ω Eye Speed Ultra Low Skew Twinax Cable. Samtec also offers an FQSFP SI Characterisation Kit for evaluation and development.
“Using the FQSFP series allows for a much longer electrical trace and convenient selection for the endpoint of the SerDes termination,” said Aaron Ram, Applications Engineer at Samtec.
“The process of routing through the FQFSP series allows designers to locate the QSFP interface much further from the ASIC or processor than traditional PCB routing would allow. This also removes the need for expensive retimers or power hungry drivers and receivers.”
