Description
The HPE 845408-B21 is a high-performance 5-meter Direct Attach Copper (DAC) cable engineered for 100 Gigabit Ethernet (100GbE) connections. It features QSFP28 connectors on both ends, enabling direct, passive connections between network devices such as switches, servers, and network interface cards (NICs) that support the QSFP28 form factor. DAC cables are a cost-effective and power-efficient solution for short-reach interconnects within data centers, typically up to 7 meters. This 5-meter cable provides ample length for connecting equipment within the same rack or adjacent racks. The copper construction ensures high signal integrity at 100Gbps speeds without the need for active optical components. This cable is ideal for high-density data center environments where high bandwidth and low latency are critical. It simplifies network infrastructure by eliminating the need for separate transceivers and fiber optic patch cords for short links, reducing both cost and complexity.
