Frequently asked questions

What is the advantage of a DAC cable over an optical transceiver at a distance of 2 meters?

A passive copper cable is cheaper, easier to connect, and requires no maintenance of optical connectors, while providing the same data transfer speed.

Does the module support speed auto-negotiation?

Passive DAC cables operate at a fixed speed of 40 Gbit/s and do not perform auto-negotiation; the equipment on both ends must support this standard.

Can the cable be used in an environment with elevated temperature?

Copper passive cables are quite resistant to heating, but the temperature norms specified by the equipment manufacturer for server rooms should be observed.
