Provides low-latency, reliable wired links for data centers, server racks and network equipment interconnects.

## Long description

The SFP28 Direct Attach Cable CBO 7Z57A03558-BL 3 m Male-to-Male 25 Gbit/s is a passive copper twinax assembly designed for short-reach, high-speed connections between SFP28-capable ports. With a 3 meter length and male-to-male SFP28 connectors, this cable provides a straightforward wired link for switches, routers and network interface cards that support 25 Gbit/s signaling. It is intended for rack-to-rack or within-rack interconnects where low latency and reliable physical layer performance are required.
Advantages
This direct attach SFP28 cable offers a high-bandwidth, low-latency connection without the need for separate transceivers, reducing power consumption and component count. The fixed-length copper design provides predictable electrical characteristics and is suitable for short-distance links, simplifying installation and reducing points of failure. Its male-to-male SFP28 termination ensures compatibility with a broad range of SFP28 ports that accept direct-attach twinax assemblies.
Suitable for
Interconnects between 25G SFP28 ports in data center switches
Connections between servers and top-of-rack or end-of-row switches
Short-reach links inside server racks and network equipment enclosures
Environments where low latency and predictable copper channel performance are required
Key specifications
Connector configuration: male-to-male SFP28 twinax
Rated data rate: 25 Gbit/s per channel
Cable length: 3 m
Physical medium: passive copper twinax assembly
Typical use: short-range, within-rack or rack-to-rack interconnects
Latency: low, suitable for high-performance networking
How to use
Install the cable by inserting each SFP28 male connector firmly into the corresponding SFP28 port until the latch clicks. Ensure both devices support direct-attach twinax assemblies and 25 Gbit/s operation. Route the cable to avoid sharp bends and excessive strain; maintain the specified minimum bend radius where indicated by the equipment guidelines. After connection, verify link status on both devices and confirm negotiated speed and link health through the network equipment management interface.
Usage recommendations
Use this 3 m SFP28 direct attach cable for short-distance, high-throughput links inside racks or between adjacent racks. Avoid using the cable beyond typical server-rack distances; for longer runs, consider optical transceivers and fiber. Store and handle the cable to prevent kinks and protect connector latches when not in use.
