Cabo de cobre Direct Attach BlueLAN 400G QSFP112, 0,5 m, compatível com Amphenol NJAAKK-0006 NJAAKK-0006-BL

High-density data centers and HPC clusters need reliable, low-latency 400G links without the cost and power draw of optical transceivers. This BlueLAN passive Direct Attach Copper (DAC) cable delivers 400GBASE-CR4 connectivity in a compact 0.5 m length, engineered for top-of-rack and adjacent-rack interconnects.

Who is it for

Network architects and data center operators deploying 400G Ethernet or InfiniBand NDR fabrics who want a plug-and-play, zero-power copper solution. It is a compatible replacement for Amphenol NJAAKK-0006 assemblies.

Tips

For best signal integrity, keep bend radius above the manufacturer's minimum and avoid stretching the cable. Passive DACs are ideal for short reaches; for longer distances consider active optical cables.
