BLUELAN Compatible Amphenol NJAAKK-0007 QSFP112 Direct Attach Cable, 400GBASE-CR4, Infiniband, 1.5 m (NJAAKK-0007-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 direct attach copper cable replaces the Amphenol NJAAKK-0007, delivering full 400GBASE-CR4 and Infiniband NDR performance over a 1.5-meter passive QSFP112 assembly.

Who is it for

Network engineers and data center operators deploying 400G Ethernet or Infiniband NDR in racks and adjacent cabinets. It is a drop-in compatible alternative to the Amphenol original, ideal for top-of-rack to server or storage connections.
