Direct Attach Copper (DAC) -kaapeli CBO BN-SP-CBL-1M 1 m SFP+ 10Gbps-yhteyksille

The BlueOptics Direct Attach Copper (DAC) Cable CBO BN-SP-CBL-1M is a 1 metre SFP+ copper cable designed for short-reach 10Gbps links between compatible SFP+ ports. This passive copper assembly provides a direct physical connection for switches, servers and storage systems, allowing high-speed data transfer with minimal latency and without separate optical transceivers. Optimised for data centre top-of-rack and rack-to-rack interconnects, the cable is a compact option where short-distance, cost-effective 10 Gigabit Ethernet connectivity is required.

Advantages

The DAC cable delivers low-latency, high-bandwidth connectivity for 10Gbps environments while reducing component count because no separate transceivers are needed. Its one-metre length minimises excess cabling in dense rack environments and supports reliable electrical signalling for short-distance links. The SFP+ form-factor ensures compatibility with devices that accept standard SFP+ copper assemblies, offering a straightforward plug-and-play installation and lower total cost of ownership compared with optical solutions for the same reach.

Key specifications

How to use

Ensure both network devices support SFP+ copper cables and operate at 10Gbps. Power down or follow hot-plug procedures recommended by your equipment manufacturer, then insert the SFP+ connectors into the corresponding SFP+ ports until they latch. Route the 1 metre cable to avoid sharp bends and excessive mechanical strain. After insertion, verify link status on both devices and confirm negotiated speed and duplex settings through switch or server management interfaces.

Recommendations

Use this 1 m DAC cable for short-distance connections inside racks or between adjacent racks. Avoid using the cable for distances beyond its intended short-reach range and keep it away from high-EMI sources. For environments requiring longer reach or optical isolation, consider fibre optic transceivers and patch cables instead.
