Cable Direct Attach SFP28 CBO SFP28-DAC-5M-LC-BL 5 m conector macho a conector macho 25 Gbit/s

CBO SFP28-DAC-5M-LC-BL is a 5-metre SFP28 Direct Attach Cable (DAC) with male-to-male connectors designed to support 25 Gbit/s link speeds. The passive copper cable provides a short-reach, fixed connection between servers, switches and storage devices without the need for separate transceiver modules. Its purpose-built construction offers low latency and consistent signal integrity for rack-to-rack or intra-rack interconnects in data centre and networking environments.

Advantages

The SFP28 direct attach cable eliminates the need for separate optical transceivers, reducing component count and simplifying installation. As a pre-terminated, fixed-length copper assembly, it provides stable 25 Gbit/s performance with low latency and predictable electrical characteristics. The male-to-male SFP28 connectors allow direct insertion into compatible SFP28 ports, offering a reliable physical connection suited to high-density rack deployments. The 5-metre length balances reach for short-reach links while keeping signal degradation and power consumption minimal.

Suitable for

• Short-reach server-to-switch connections within racks
• Rack-to-rack interconnects in data centres
• High-density top-of-rack switch uplinks
• Storage array connections requiring 25 Gbit/s copper links

Key specifications

• Connector type: SFP28 male-to-male
• Cable length: 5 metres
• Maximum data rate: 25 Gbit/s
• Cable medium: copper direct attach
• Latency: low, suitable for short-reach interconnects
• Typical application: short-reach server, switch and storage interconnects

How to use

Insert each SFP28 connector into the SFP28 port of the hosting devices until the latch engages. Ensure both ends are securely seated and that the connected devices are powered and configured for 25 Gbit/s operation. Avoid sharp bends and do not stretch the cable; maintain standard data-centre cable management practices to prevent mechanical stress. If the host devices implement port validation or vendor locking, verify compatibility or enable the necessary settings in device firmware or configuration.

Recommendations

Use this SFP28 DAC for short-distance links where a fixed, low-latency copper connection is acceptable. For distances beyond the cable length or environments requiring optical isolation, consider fibre-based transceivers instead. Keep the cable within recommended bend radius and ambient temperature ranges specified by your equipment vendors to ensure reliable performance.
