HP X242 40G QSFP+ DAC Cable

Practical limits of 3m passive copper

A three-metre passive assembly works reliably inside a single rack or adjacent cabinets, but signal integrity drops beyond this length without active electronics. Buyers who need longer runs or fibre connectivity must choose a different cable type.
