Cisco 3.3ft 25G SFP28 Copper Cable

The Cisco SFP-H25G-CU1M= is a one-meter direct attach copper cable that creates a dependable 25-Gigabit link between devices equipped with SFP28 ports. Built around a twinaxial design, it offers the speed of 25GBase-CR1 connectivity without the added cost or complexity of optical transceivers and fiber, making it a sensible choice for short-reach connections inside the rack or to an adjacent rack.

This cable fits naturally in data centers or enterprise wiring closets where high-bandwidth traffic needs to stay local. Network administrators often use it to stack top-of-rack switches, connect servers to leaf switches, or tie storage appliances into the network fabric. Its compact length keeps cable management simple, reduces slack, and helps maintain clear airflow paths in crowded racks.

Cisco built the cable to meet IEEE 802.3by and SFF-8402 standards, so it works seamlessly with compliant equipment and maintains stable performance under continuous load. The durable black jacket blends into existing cable runs, and the included one-year warranty provides added confidence during deployment.
