CBO SFP28 Direct Attach Cable SFP28-DAC-5M-IB-BL 5 m Male-to-Male 25 Gbit/s

The CBO SFP28 Direct Attach Cable SFP28-DAC-5M-IB-BL is a 5 m passive twinax copper cable with SFP28 male connectors at both ends, engineered for 25 Gbit/s short-reach links. It provides a direct, low-latency electrical connection between network devices that accept SFP28 form-factor DACs, such as switches, network interface cards (NICs) and servers in data center or rack-to-rack environments. The cable is intended for high-density deployments where power efficiency and consistent signal integrity are required.

Advantages

This passive SFP28 direct attach cable offers a fixed, low-power alternative to active optical or breakout solutions while maintaining full 25 Gbit/s throughput. The male-to-male SFP28 interfaces ensure broad compatibility with SFP28 ports designed for DAC use, and the 5 m length supports typical rack-to-rack and within-rack connections without additional transceivers. Low latency and reduced heat generation make it suitable for densely populated switch and server racks.

Suitable for

• High-speed 25 Gbit/s links between switches and aggregation devices
• Direct server-to-switch or NIC-to-switch connections in data centers
• Short-reach rack-to-rack interconnects in colocation and enterprise racks

Key specifications

• Connector type: SFP28 male-to-male twinax
• Data rate: up to 25 Gbit/s
• Length: 5 meters
• Cable type: passive direct attach (twinax copper)
• Latency: low electrical latency suitable for time-sensitive traffic
• Power consumption: passive design with no additional power draw for active components

How to use

Insert each SFP28 male connector into the corresponding SFP28 port on the devices to be connected, ensuring secure latch engagement. Confirm link status on both devices and verify negotiated speed of 25 Gbit/s. No external power or configuration is required for the passive cable itself; any necessary interface settings should be managed through the connected devices’ network management interfaces. For best results, route the cable to avoid sharp bends and maintain manufacturer-recommended bend radius.

Recommendations

Use this 5 m passive SFP28 DAC for short-range, high-throughput interconnects where low latency and low power are priorities. Confirm compatibility with your device vendor’s SFP28 DAC policy and ensure ports are compatible with passive twinax cables before deployment. Avoid excessive bending and exposure to mechanical stress to preserve signal integrity.
