Cable de cobre de conexión directa SFP28 CBO SFP28-DAC-5M-SP-BL 5 m conector macho a conector macho 25 Gbit/s

The BlueOptics SFP28 direct-attach copper cable CBO SFP28-DAC-5M-SP-BL is a 5 m male-to-male SFP28 cable engineered for short-reach 25 Gbit/s connections. It provides a low-latency, low-power physical link between SFP28 ports on switches, servers and network appliances. The passive copper construction eliminates the need for separate optical transceivers for short-distance patching in data center top-of-rack and leaf-spine deployments.

Advantages

This SFP28 direct-attach copper cable supports 25 Gbit/s throughput with minimal signal conditioning, delivering predictable latency and power efficiency compared with active optical alternatives for short links. Its male-to-male SFP28 form factor ensures compatibility with standard SFP28 cages and hot-pluggable ports. A fixed 5 m length simplifies cable management for rack-to-rack or within-rack connections while maintaining electrical performance suitable for high-density deployments.

Suitable for

• Short-reach 25 Gbit/s connections between top-of-rack switches and servers
• High-speed uplinks within data center racks and between adjacent racks
• Patch connections in environments where optical transceivers are not required
• Low-latency links for network appliances, storage arrays and compute nodes

Key specifications

• Connector type: SFP28 male-to-male
• Length: 5 meters
• Data rate: 25 Gbit/s per link
• Medium: Direct-attach copper (passive DAC)
• Typical use: Short-reach, within-rack or adjacent-rack connections
• Form factor: Hot-pluggable, SFP28 compatible

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your network device until the latch engages. Ensure both devices support 25 Gbit/s SFP28 direct-attach copper connections and have compatible port settings. No separate powering or transceiver modules are required; the cable draws required signaling over the copper conductors. Test the link after installation to confirm negotiated speed and link stability, and route the cable to avoid sharp bends or mechanical strain.

Recommendations

Use this 5 m SFP28 DAC for short-distance links where optical modules are unnecessary. Maintain manufacturer-recommended bend radius and avoid excessive pull force when routing. For longer distances or where electrical interference is a concern, consider appropriate active optical or fiber solutions.
