IBM BN-QS-QS-CBL-5M - kompatibles 40G QSFP+ passives Kupfer Direct Attach Kabel (DAC), 5m (16ft)

This FS.COM 40G QSFP+ passive copper direct attach cable (DAC) is engineered for short-reach, high-density interconnects in data centers and enterprise networks. Unlike optical transceivers that require separate fiber cabling and add latency, this integrated twinax assembly delivers plug-and-play 40GbE connectivity with ultra-low power consumption under 0.5W. The 5-meter length (16.4 ft) bridges top-of-rack switches to servers or storage arrays without the bulk or cost of active optical cables. Fully compatible with IBM BN-QS-QS-CBL-5M, it is a direct replacement for IBM part numbers in QSFP+ ports.

Highlights

• Passive copper twinax design – no signal processing, minimal latency, and negligible heat generation
• QSFP+ to QSFP+ connectors support 40GBASE-CR4 Ethernet, InfiniBand QDR/FDR, and Fibre Channel
• 26 AWG thick-gauge conductors ensure signal integrity over the full 5 m reach
• Hot-swappable and RoHS compliant, with PVC jacket for durability in dense cabling environments
• 100 Ohm impedance matched to industry standards for reliable error-free operation

In daily use

Deploy this DAC to link 40G QSFP+ ports on switches, NICs, and storage controllers. Its passive nature means no firmware, no configuration, and no compatibility issues – just insert and link. The flexible yet robust cable routes easily through cable management arms, and the low-profile connectors allow side-by-side stacking in high-port-count switches. With an operating temperature range of 0°C to 70°C, it performs reliably even in hot aisles. Power draw is less than 0.5W, contributing to overall energy efficiency in large-scale deployments.
