Direct-attach cable for QSFP+ ports

This Axiom passive twinax cable links two QSFP+ network interfaces over a fixed 16.40 ft run. It targets data-centre racks and campus switches where short-reach, low-latency links replace optical modules. The twinax construction keeps power draw near zero and removes transceiver compatibility checks.

Passive design removes active components

No on-board electronics mean the cable draws no power and generates no heat, simplifying thermal budgets in dense panels. The fixed length eliminates slack management but prevents re-termination if port layouts change. Lifetime limited warranty covers the assembly against manufacturing defects.

Plug into matching QSFP+ cages and lock

Installation is a straight push until the latch clicks; no drivers, firmware or configuration are required. Common issues arise when the cable is bent tighter than the minimum bend radius or when a port expects an active or optical module instead of a passive copper assembly.

Questions about this item

Will the QSFP+ connectors on this 16.40 ft twinax cable need periodic cleaning or replacement?

The passive twinax cable has no active components; connectors only need cleaning if contaminated and do not wear out under normal insertion cycles.

What is the first performance limit reached when running this 16.40 ft passive twinax link continuously at 40 Gbps?

Signal attenuation over the 16.40 ft length is the primary limit; the passive design relies on host equalisation to maintain link integrity.

Does this 16.40 ft passive twinax cable generate any heat or noise during all-day operation?

No — it draws zero power, produces no heat and has no moving parts, so it runs completely silent.
