DAC kábel CBO SFP-10G-DAC-0.5M 10 Gbit/s 0,5 m, Direct-Attach SFP+ pasívny medený

Direct-attach copper (DAC) cable CBO SFP-10G-DAC-0.5M provides a 10Gbps SFP+ connection over a 0.5 meter passive copper link. Designed for short-range connections between compatible SFP+ ports on switches, servers or network appliances, the cable delivers low latency and a straightforward plug-and-play installation without requiring optical transceivers. The compact, low-profile SFP+ modules are integrated into a single cable assembly intended for rack-to-rack or chassis-to-chassis links in data centers and server rooms.

Advantages

The SFP+ passive copper cable offers a reliable and cost-effective method to establish 10Gbps links for short distances. Its passive design reduces power consumption compared with active or optical alternatives and eliminates the need for separate transceivers, simplifying inventory and deployment. With a half-meter length, the cable minimises signal attenuation at short spans and keeps cable management tidy in dense rack environments.

Suitable for

• Short-range interconnects between SFP+ ports in switches and routers
• Server-to-switch or switch-to-switch connections within the same rack or adjacent racks
• High-density data centre patching where low latency and compact cabling are required
• Environments where plug-and-play 10Gbps links are preferred without optical transceivers

Key specifications

• Data rate: 10 Gbps
• Connector type: SFP+ direct-attach
• Cable type: Passive twinax copper assembly
• Length: 0.5 m
• Power: passive (no active electronics)
• Typical use range: short-reach / within-rack or adjacent-rack

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be connected until the latch clicks into place. Ensure both devices are powered and configured to use 10Gbps SFP+ links; the link should be negotiated automatically if the ports support passive DAC modules. Remove the cable by depressing the connector latch and pulling the module straight out to avoid damaging the port.

Recommendations

Use the DAC cable for short, direct connections inside racks or between adjacent racks; avoid exceeding the recommended distance for passive copper assemblies. Keep the cable free of sharp bends and ensure adequate airflow around equipment. For longer distances or when greater flexibility is required, consider active copper or optical solutions.
