SFP28 Direct Attach Cable CBO JH956A 25G 100m

SFP28 Direct Attach Cable CBO JH956A 25G 100m is a passive copper direct attach solution from BlueOptics designed for 25 Gbps links up to 100 meters. It connects compatible SFP28 ports in switches, servers and storage equipment, providing a single-cable option for short- to mid-range interconnects. The cable is intended for environments that require reliable, low-latency connectivity and straightforward cabling in data centers or enterprise network racks.

Advantages

This SFP28 direct attach cable supports 25 Gbps data rate and offers a fixed-length, factory-tested interconnect that eliminates the need for separate transceivers. The single-cable design simplifies rack cabling and reduces component count, while copper construction provides predictable latency and power characteristics. Compatibility with standard SFP28 ports ensures plug-and-play operation in supported hardware and reduces installation time.

Suitable for

• Short- to mid-range connections between SFP28 ports in switches and servers
• Top-of-rack and middle-of-row data center interconnects
• Interlinking storage arrays and host adapters supporting 25 Gbps
• Laboratory and test environments requiring stable 25 Gbps links

Key specifications

• Data rate: 25 Gbps
• Length: 100 meters
• Form factor: SFP28 direct attach cable
• Cable type: Copper direct attach
• Typical use: Short- to mid-range parallel interconnects

How to use

Install the cable by inserting each SFP28 module end into the corresponding SFP28 port on the devices to be connected, ensuring the connector latches engage. Verify that both devices are powered and that ports are enabled and configured for 25 Gbps operation. No additional optics or modules are required; the cable functions as both the connector and link medium. Check link status in device management interfaces to confirm a stable connection and correct negotiated speed.

Recommendations

Route the cable to avoid sharp bends and high-tension pulls; maintain manufacturer minimum bend radius and avoid electromagnetic interference sources. Use within supported temperature and humidity ranges of the networking equipment, and verify hardware compatibility with SFP28 passive copper cables before deployment to ensure proper operation.
