Description
The HPE Aruba Networking 100G QSFP28 to QSFP28 3m Direct Attach Copper Cable (JL307A) offers a cost-effective and reliable interconnect solution for short-range data center and high-performance networking environments. Designed for high-speed 100G Ethernet connectivity, this passive direct attach copper (DAC) cable provides seamless integration between HPE Aruba switches and compatible networking devices using QSFP28 ports.
With its 3-meter length, this DAC cable is ideal for top-of-rack (ToR) or middle-of-row (MoR) deployments, eliminating the need for expensive optical transceivers and fiber cabling. It ensures low power consumption and low latency, making it an excellent choice for high-density environments looking to optimize performance and reduce operating costs.
