Tripp Lite SFP28 to SFP28 25GbE Passive Twinax Copper Cable (M/M), SFP-H25G-CU3M Compatible, Black, 3 m (9.8 ft.)

The Tripp Lite N280-03M-28-BK is a cable that uses passive twinax copper construction to link two SFP28 ports at 25 Gigabit Ethernet speed over a 3 meter run. It gives network teams a straightforward way to connect top-of-rack switches to servers, storage shelves, or neighboring switches without the expense or power draw of optical transceivers.

The assembly arrives with factory terminated SFP28 direct-attach connectors. Each connector is molded from zinc die cast material that shields sensitive circuitry from electromagnetic noise commonly found in crowded data center cabinets. An easy to grip pull tab lets you release the latch even when nearby ports are packed with other cables, so routine moves, adds, and changes stay quick.

Because the design follows SFF 8432 and IEEE 802.3by guidelines, it works right out of the box with hardware from Cisco, Arista, Dell, Juniper, Mellanox, and other vendors that accept SFP-H25G-CU3M equivalents. Administrators can drop it into leaf-spine fabrics, hyper-converged clusters, or lab test benches with no special configuration.

The PVC jacket bends easily, allowing neat routing through cable managers or around airflow paths. A passive architecture means zero power consumption, less heat, and fewer points of failure. Tripp Lite backs the cable with a lifetime limited warranty, offering peace of mind for long-term deployments in enterprise environments, university labs, or cloud hosting facilities.
