SFP28 Direct-Attach medený kábel CBO SFP28-DAC-5M-PT-BL 5 m samec-na-samca 25 Gbit/s

CBO SFP28-DAC-5M-PT-BL is a 5-meter direct-attach copper (DAC) cable with SFP28 male connectors on both ends, engineered for 25 Gbit/s links. It is intended for short-reach connections between switches, network interface cards and servers in data center racks. The cable offers a compact, low-latency physical connection that reduces power consumption compared with optical transceivers and eliminates the need for separate modules and patch cords for short distances.

Advantages

This SFP28 direct-attach cable delivers a reliable 25GbE physical link with minimal signal loss and very low latency. Its fixed-copper design provides energy-efficient operation and simplifies installation by combining connector and cable into one pre-tested assembly. The cable’s length and gauge are optimized for short-reach rack-to-rack and within-rack interconnects, ensuring consistent performance in high-density environments while reducing rack clutter and total cost of ownership for short links.

Suitable for

• Short-reach links between top-of-rack switches and leaf switches
• Direct connections between servers and network interface cards (NICs)
• Inter-rack or within-rack connections in data centers and server rooms
• High-density switch-to-switch uplinks in 25GbE deployments

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 5 meters
• Data rate: up to 25 Gbit/s
• Medium: direct-attach copper (DAC)
• Form factor: fixed assembly, pre-terminated
• Typical use range: short-reach (within-rack and adjacent racks)

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your switch, server or NIC until it latches. Ensure the equipment is powered down or follows hot-plug guidelines from the equipment vendor if required; many devices support hot-plugging SFP28 DACs. After insertion, verify link status and speed on the network device management interface. For removal, release the latch mechanism and pull the connector straight out to avoid stress on ports. Handle the cable by the connector bodies to avoid bending the assembly near terminations.

Recommendations

Use this 5 m SFP28 DAC for short-distance 25GbE interconnects where optical transceivers are unnecessary. Avoid running the cable next to high-power electrical lines to reduce electromagnetic interference. Follow the host equipment vendor’s supported cable lists and firmware guidelines to ensure compatibility and optimal link performance.
