HPE 100Gb QSFP28 to QSFP28 3m Direct Attach Copper Cable

The HPE 845406-B21 is a 3-meter direct attach copper cable designed to connect two QSFP28 ports at speeds up to 100Gbps. It provides a straightforward, reliable way to link high-speed networking equipment, especially in environments like data centers or server racks where short-distance connections are common. This cable supports 100GBase direct attach standards, ensuring compatibility with a wide range of devices including HPE switches as well as equipment from Cisco, Arista, and Juniper.

With a copper construction and an 8.8 mm diameter, the cable is flexible enough to fit into tight spaces, featuring a minimum bend radius of 45 mm. This flexibility makes it easier to manage cabling in dense setups without risking damage or signal loss. The cable also maintains low latency, with a signal delay of just 4.5 nanoseconds per meter, which helps keep data transmission fast and efficient.

Built to meet the SFF-8665 standard and designed to operate reliably within a temperature range of 32 to 158 degrees Fahrenheit, this cable is a practical choice for professionals who need dependable, high-speed connections in demanding network environments. Whether you are upgrading existing infrastructure or setting up new equipment, the HPE 845406-B21 offers a plug-and-play solution that minimizes complexity and maximizes performance.
