CBO SFP28 Direct Attach kábel SFP28-DAC-5M-IX-BL 5 m konektor samec na konektor samec 25 Gbit/s

CBO SFP28 Direct Attach Cable SFP28-DAC-5M-IX-BL 5 m Male-to-Male 25 Gbit/s is a 5-metre passive copper direct attach cable designed for short-reach, high-speed interconnects between SFP28 ports. The cable supports 25 Gbit/s data rates and is tailored for connections between switches, servers and network appliances in rack-mounted data centre environments. Its compact, male-to-male SFP28 connectors provide a plug-and-play physical link that minimises latency and signal loss over short distances.

Advantages

This SFP28 direct attach cable delivers a cost-effective, low-power alternative to optical transceivers for short-distance links. The integrated male-to-male SFP28 ends reduce the number of separate modules and simplify installation. Its passive copper design provides consistent signal integrity at 25 Gbit/s within the specified reach while maintaining a compact footprint suitable for dense rack deployments.

Suitable for

• Short-reach connections between SFP28 ports on switches and routers
• Direct links between servers and top-of-rack switches
• Interconnects in blade servers and network appliances
• Data centre patching and rack-to-rack horizontal connections within the same equipment room

Key specifications

• Length: 5 metres
• Connector type: SFP28 male-to-male
• Maximum data rate: 25 Gbit/s
• Transmission medium: Passive copper direct attach
• Form factor: SFP28 compatible small form-factor pluggable
• Typical use: Short-reach, up to the specified cable length in rack environments

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring each connector latches securely. No additional configuration or transceiver modules are required; the cable functions as a plug-and-play physical link. Verify link status through the host equipment's management interface and confirm the negotiated speed is 25 Gbit/s. For best results, route the cable to avoid sharp bends and electromagnetic interference from high-power sources.

Recommendations

Use this direct attach cable for short, high-speed connections within racks or neighbouring racks. Avoid exceeding the specified 5 m length and keep the cable away from heat sources and tight cable management bends to preserve signal integrity. Confirm compatibility with device SFP28 ports and firmware to ensure proper link negotiation.
