Suitable for data centers and HPC environments where short-range, low-latency 25/100 Gb connections are required.

## Long description

This CBO InfiniBand cable CAB-Q28-S28-5M-BL is a 5-meter, blue direct-attach data cable with four SFP28 connectors designed for short-reach high-speed links. It provides low-latency, high-throughput connectivity between servers, switches and storage devices equipped with SFP28 ports, supporting environments where reliable 25/100 Gb interconnects are required. The cable is intended for data center racks and high-performance computing setups that prioritize compact, low-power, point-to-point connections.
Advantages
The cable offers a compact, direct-attach solution that reduces the need for active transceivers and fiber patching for short-distance connections. Its SFP28 interface provides compatibility with ports supporting 25 Gb and multi-lane 100 Gb configurations, enabling flexible deployment across modern switch and server hardware. The 5 m length balances reach and signal integrity for rack-to-rack or within-rack connections while the durable outer jacket and color coding simplify installation and maintenance in dense cabling environments.
Suitable for
 Direct-attached links between servers and top-of-rack or leaf switches
 Short-range connectivity in data centers and HPC clusters
 Interconnects for storage arrays and NVMe over Fabrics setups with SFP28 ports
 Replacement or expansion cabling in rack deployments requiring 25 Gb or 100 Gb lanes
Key specifications
 Connector type: 4 × SFP28 direct-attach
 Cable length: 5 meters
 Color: blue outer jacket
 Supported data rates: compatible with 25 Gb single-lane and aggregated 100 Gb configurations
 Intended reach: short-range / within- or between-rack connections
 Usage: passive copper direct-attach cable for low-latency links
How to use
Install the cable by inserting each SFP28 connector firmly into the corresponding SFP28 port on your server, switch or storage device until the latch engages. Route the cable in the rack to avoid tight bends and mechanical strain; maintain bend radii according to equipment guidelines. Verify link negotiation and speed in the host or switch management interface and ensure firmware and driver compatibility with SFP28 direct-attach cables. For best results, label both ends to match port assignments and document the connection in your rack diagram.
Usage recommendations
Use this direct-attach SFP28 cable for short, low-latency 25/100 Gb links inside racks or between adjacent racks. Avoid using it for long runs beyond the recommended short-reach scope, and ensure ports explicitly support passive or active direct-attach cables as required. Store and handle the cable to prevent sharp bends, kinks or exposure to excessive heat to maintain signal integrity.
