QSFP+ to QSFP+ Passive DAC

Our 40GBase-CU QSFP+ to QSFP+ direct attach cable operates over passive copper available in lengths of between 0.5-10m. It is suitable for short reach connection between two QSFP+ ports in 40G interconnecting networking applications. It consists of a shielded twinax copper cable with pluggable connectors on either end.

Our 40G Passive Direct Attach Cables are used in short reach, high density, high speed interconnect data centre applications. They are designed for networking, data storage and telecom systems where you need the highest possible network efficiency, low power consumption and low latency at an affordable price. Passive DAC cables have no electrical components built into the cable assembly and are most often used to connect equipment located within the same data rack with short transmission distance requirements, typically 1-2m. That said we do offer 0.5-10m lengths.

We recommend a Passive DAC is used for transmission of up to 7m and an Active DAC is suitable for 7-15m.
