Keep short-range 40G links direct, predictable, and cost-controlled with this INTELLINET QSFP+ passive DAC twinax cable. Designed for QSFP+ ports, it delivers a copper interconnect path that avoids the added expense, power draw, and heat of separate optical transceivers. Passive DAC cabling is a strong fit for top-of-rack and adjacent-rack deployments where distance is limited and link stability matters more than optical reach. By using an integrated twinax assembly, this cable helps reduce component count and simplifies procurement for dense switching environments. For infrastructure teams standardizing on 40G uplinks, this cable supports a cleaner bill of materials and faster deployment. It is a practical choice when you need dependable short-run connectivity between compatible QSFP+ devices without overbuying optics for a link that does not require them.
