SFP28 DAC Cable CBO SFP28-DAC-5M-MV-BL — 5 m, male-to-male, 25 Gbit/s

Direct Attach Copper (DAC) SFP28 cable CBO SFP28-DAC-5M-MV-BL is a 5 m, male-to-male, high-speed interconnect designed for short-range 25 Gbit/s links. This fixed cable integrates copper twinax wiring with SFP28-compatible connectors to provide a stable physical connection between servers, switches and other network devices without requiring separate transceivers. The cable is intended for use in dense data centre environments where predictable latency, low power consumption and simple deployment are priorities.

Advantages

The SFP28 DAC cable delivers low latency and reduced power usage compared with optical transceiver-based connections, since no separate modules are required. Its pre-terminated male-to-male design simplifies installation and reduces the number of field terminations, enabling quick rack-to-rack and top-of-rack connections. The 5 m length balances reach and cable management for common data centre layouts, while the robust connectors and fixed assembly ensure consistent electrical performance and signal integrity for 25 Gbit/s operation.

Suitable for

• Top-of-rack (ToR) uplinks in server racks
• Switch-to-switch short-range connections within the same rack or adjacent racks
• High-density data centre patching and aggregation layers
• Server NIC to switch links in storage and compute clusters

Key specifications

• Nominal data rate: 25 Gbit/s
• Length: 5 meters
• Connector type: SFP28 male-to-male (twinax)
• Cable medium: Direct attach copper (twinax), fixed assembly
• Typical use range: short-reach, data centre interconnects
• Latency: low, suitable for latency-sensitive applications
• Power: lower consumption compared with optical transceiver solutions

How to use

Install the cable by plugging each SFP28 connector into the corresponding SFP28 port on your switch, server or network device. Verify that both devices support SFP28 DAC connections and that port settings (speed and duplex) are configured for 25 Gbit/s operation. Route the cable to avoid sharp bends and maintain recommended bend radius; secure the cable to rack infrastructure as needed to prevent strain on connectors. After connection, check link status in device management interfaces to confirm a stable 25 Gbit/s link.

Recommendations

Use this 5 m SFP28 DAC cable for short, high-bandwidth links inside racks or between adjacent racks. For longer distances or optical isolation requirements, consider optical transceivers and fibre cabling. Ensure device compatibility with SFP28 DACs and follow manufacturer guidance on supported passive twinax assemblies to guarantee interoperability.
