Features
The Cisco SFP-H25G-CU3M is a 25GBASE-CR1 passive copper direct attach cable (DAC) designed for high-speed data center and enterprise networking. It supports 25 Gigabit per second (25 Gbps) Ethernet links, delivering ultra-fast data transfer performance between network devices such as switches, routers, and servers that have SFP28 ports. Ideal for short-distance connections inside racks or across adjacent racks, this cable provides reliable, low-latency connectivity without the need for optical modules.
Passive Copper Direct Attach Design
As a passive twinax copper cable, the SFP-H25G-CU3M doesn't contain active circuitry or require external power, which helps keep power consumption and costs down relative to optical solutions. The cable has SFP28 connectors on both ends that plug directly into SFP28-equipped network ports, making it hot-swappable and plug-and-play for easy installation.
3-Meter Length for Flexible Deployment
With a 3m (10 ft) cable length, this direct attach cable provides flexibility for connecting devices that are nearby but not directly adjacent - for example, between top-of-rack switches and adjacent servers or storage appliances within the same cabinet or row. This length strikes a good balance between reach and signal integrity for short-range high-speed links in data center environments.
Typical Use Cases & Benefits
This cable is commonly used in data centers, enterprise LANs, high-performance computing clusters, and storage applications where short-reach, high-bandwidth connectivity is needed but optical transceivers and fiber patch cords would be overkill or more expensive. The passive DAC design helps minimise total cost of ownership (TCO) and simplifies link deployment while delivering stable performance suitable for demanding network environments.
