Q&A
What data rate does this QSFP+ DAC support?
The cable supports a 56Gbps-class aggregate data rate using four electrical channels, with each channel operating at up to 14.3125Gbps.
What lengths and wire gauges are available?
The cable is available in lengths from 1m to 7m and conductor gauges from 30 to 24 AWG. The appropriate combination can be selected according to rack layout, cable management, and power requirements.
Is this DAC cable passive or active?
It is a passive DAC cable. It uses direct copper electrical connections and does not require optical components or active signal processing, resulting in low power consumption and cost.
When should I choose a 56G QSFP+ DAC instead of an optical cable?
The DAC is well suited to short-distance connections within or between adjacent racks where low cost, low power consumption, and simple deployment are priorities. For longer distances, an optical transceiver or AOC may be more appropriate.
Can the cable be customized?
Yes. Options such as cable length, conductor gauge, and other cable construction specifications can be customized for different deployment requirements, subject to product design and compatibility.
