BlueLAN Cable direct attach 40G QSFP+ 3 m, compatible con Fortinet FN-CABLE-QSFP+3 FN-CABLE-QSFP+3-BL

Data center technicians connecting Fortinet switches and servers over short distances rely on this BlueLAN 40G QSFP+ direct attach cable. It links two QSFP+ ports with a 3-meter passive copper assembly, delivering 40GBASE-CR4 throughput without the cost or power draw of optical transceivers.

Key specifications

• 40 Gigabit Ethernet (40GBASE-CR4) passive copper DAC
• QSFP+ to QSFP+ connectors, 3 m length
• 26 AWG conductors, 100 Ohm impedance, PVC jacket
• Hot-swappable, power consumption under 0.5 W per end
• Operating temperature 0 °C to 70 °C
• Supports Ethernet and InfiniBand protocols
• Compatible with Fortinet FN-CABLE-QSFP+3

Why choose it

This cable eliminates the need for separate transceivers, reducing both cost and latency in high-density racks. Its passive design draws minimal power and produces no heat, helping to keep cabinet temperatures down.

Ideal use cases

• Top-of-rack to end-of-row switch connections
• Server to storage interconnects in HPC clusters
• Short-reach 40G Ethernet or InfiniBand links

Good to know

The cable is RoHS, CE and FCC compliant and built for hot-swappable operation, so it can be replaced without powering down the connected equipment.
