Cabo de ligação direta SFP28 CBO SFP28-DAC-5M-AO-BL 5 m macho-macho 25 Gbit/s

CBO SFP28-DAC-5M-AO-BL is a 5 metre SFP28 direct attach cable with male-to-male connectors designed to deliver a fixed 25 Gbit/s connection for short-reach interconnects. The passive copper assembly removes the need for separate optical transceivers, enabling low-latency, energy-efficient links between servers, switches and storage devices in data centre and rack-to-rack environments.

Advantages

This direct attach cable supports full 25 Gbit/s line rate while keeping power consumption and latency to a minimum compared with active optical modules. The male-to-male SFP28 connector ends offer plug-and-play compatibility with standard SFP28 ports. With a 5 metre length, the cable is intended for short-range connections inside racks or between adjacent racks, providing a cost-effective, reliable alternative to fiber optics for fixed-length links.

Suitable for

• Server-to-switch connections inside a rack
• Switch-to-switch rack-to-rack links over short distances
• Storage area network (SAN) interconnects requiring 25 Gbit/s
• Top-of-rack and end-of-row wiring in data centres

Key specifications

• Data rate: 25 Gbit/s
• Length: 5 metres
• Connector type: SFP28 male-to-male
• Media: copper direct attach cable (passive)
• Intended reach: short-range, intra-rack and adjacent-rack links

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the networking devices until the latch clicks to secure the connection. Ensure both devices support SFP28 copper direct attach cables and are configured for 25 Gbit/s operation. Avoid sharp bends and strain on the cable; route it to prevent interference with airflow in racks and to maintain adequate bend radius for copper assemblies.

Recommendations

Use this cable for fixed, short-distance links where a reliable 25 Gbit/s connection is required and where transceiver-based solutions are not necessary. Verify device compatibility and port settings before deployment. For longer distances or optical isolation requirements, choose appropriate fiber optics solutions instead.
