STARTECH QSFP+ Direct Attach Cable .5 m 1.6 ft 40G

SKU CH-BNYA-WE01X

QSFP+ direct attach cable, 0.5 m (1.6 ft) for 40G links

  • 5 m reach keeps 40 GbE links tidy in adjacent racks
  • 6 ft length matches short intra-cabinet runs exactly
  • Cisco QSFP-H40G-CU0-5M code guarantees drop-in compatibility
  • 3 ft alternative covers slightly longer patch-panel spans

STARTECH QSFP+ Direct Attach Cable .5 m

This 40G QSFP+ direct attach cable provides a high-speed link between compatible network devices. The 0.5 metre length suits short rack connections. It is built for data-centre and enterprise environments that need a reliable passive copper interconnect.

Cisco QSFP-H40G-CU0-5M compatible alternative

The cable matches the Cisco QSFP-H40G-CU0-5M specification so it works in Cisco gear without extra licensing. It also replaces the Juniper QFX-QSFP-DAC-1M for cross-vendor deployments. Buyers needing longer reaches or active optical cables will need a different product.

Questions about this item

Does the QSFP+ direct attach cable require any scheduled maintenance or connector replacement over time?

The passive copper cable has no active components or moving parts, so it does not need scheduled maintenance or connector replacement under normal use.

What is the first limit encountered when running the 40G link continuously at full throughput?

The 0.5 m length and passive copper construction keep insertion loss and latency minimal, so the link stays within the 40G specification without hitting a distance or signal-quality ceiling.
