SFP28 direct-attach cable CBO SFP28-DAC-5M-MA-BL 5 m Male-to-Male 25 Gbit/s

CBO SFP28-DAC-5M-MA-BL is a 5 m direct-attach copper cable with SFP28 male-to-male connectors that supports a 25 Gbit/s data rate. It is intended for short-reach, high-speed links between SFP28 ports on switches, servers and network interface cards, offering low latency and plug-and-play connectivity for rack and data centre environments.

Advantages

The cable provides a reliable short-range connection with minimal signal loss and low power consumption compared with optical transceivers. Its fixed-length, twinax design ensures predictable latency for server-to-switch and switch-to-switch links. The male-to-male SFP28 connectors enable hot-pluggable installation and immediate compatibility with devices that accept SFP28 DAC modules. The 5 m length is suitable for connections across adjacent racks or within larger server cabinets.

Suitable for

• Interconnecting top-of-rack switches and server NICs operating at 25 Gbit/s
• Short-distance uplinks between switches in the same rack or neighbouring racks
• Low-latency connections for virtualization, storage and compute clusters

Key specifications

• Data rate: 25 Gbit/s
• Connector type: SFP28 male-to-male
• Cable type: Direct-attach copper (twinax)
• Length: 5 metres
• Form factor: Fixed-length DAC for hot-pluggable SFP28 ports
• Typical use: Short-reach, in-rack and adjacent-rack links

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your switch, server or NIC until the latch engages. Ensure both devices support SFP28 DAC modules and are powered according to the vendor's instructions before connecting. No additional transceivers or optical modules are required. For best results, avoid sharp bends and excessive tension on the cable, and verify link status through device management interfaces after connection.

Recommendations

Use this 5 m SFP28 direct-attach cable for short-distance, high-bandwidth connections inside racks or between adjacent racks. Confirm compatibility with your network equipment and firmware, keep the cable routed to minimise electromagnetic interference, and replace the cable if the connectors show physical damage or the link becomes unstable.
