Direct Attach -kaapeli CBO SFP28-DAC-5M-CO-BL 5 m uros-uros 25 Gbit/s SFP28

CBO SFP28-DAC-5M-CO-BL is a 5 meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, supporting a 25 Gbit/s data rate. It provides a short-reach, low-latency physical connection for network switches, routers and host adapters that accept SFP28 DAC modules. The cable is designed for plug-and-play installation in data centers and server rooms where cost-effective, high-speed links are required.

Advantages

The SFP28 direct attach cable offers high bandwidth at 25 Gbit/s while maintaining low power consumption compared with optical transceivers. Its fixed copper assembly delivers deterministic performance with minimal signal processing latency. The 5 m length balances reach and signal integrity for typical rack-to-rack and within-rack connections. The male-to-male SFP28 connectors are hot-pluggable for easy replacement or reconfiguration without shutting down equipment.

Suitable for

• Short-reach connections between top-of-rack and end-of-row switches
• Interconnects between servers and 25G NICs or switch ports
• High-density patching in data center racks
• Low-latency links for virtualization and storage traffic

Key specifications

• Cable type: direct attach copper (DAC)
• Connector type: male SFP28 on both ends
• Data rate: 25 Gbit/s
• Length: 5 meters
• Typical application: short-range rack and cabinet interconnects
• Performance: low latency, passive copper link

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the devices to be connected, ensuring the connector latches are fully engaged. No additional configuration is required at the physical layer; the cable establishes the electrical link immediately after hot-plugging. Verify link status through device LEDs or management interfaces and confirm negotiated speed is 25 Gbit/s. For replacement, remove one end by depressing the latch and pulling straight out, then insert the replacement connector in the same manner.

Recommendations

Use the cable for short-distance links within the same rack or between adjacent racks; avoid routing through cable trays or pathways that exceed the recommended bend radius. Keep connectors free of dust and avoid excessive mechanical stress. For environments requiring extended reach or optical isolation, consider active optics or fiber-based transceivers instead of passive copper DACs.
