Direct Attach Copper (DAC) Cable CBO SFP-10G-DAC-0.5M 10G 0.5 m for SFP+ ports

CBO SFP-10G-DAC-0.5M is a 0.5 m Direct Attach Copper (DAC) cable with SFP+ connectors designed to support 10 Gbit/s links between SFP+ ports. It is intended for short-range interconnects in data centers, server rooms and network closets, providing a compact, low-latency physical connection without separate optical transceivers. The cable is suitable for within-rack and rack-to-rack links where short distances and cost-efficient, power-saving connectivity are required.

Advantages

The DAC cable offers reduced latency and lower power consumption compared with active optical solutions thanks to its passive copper design. Its integrated SFP+ connectors simplify installation by plugging directly into SFP+ ports, eliminating the need to install separate transceivers. The fixed length of 0.5 m minimizes unneeded slack and supports neat cable management in dense rack environments, while the metal-reinforced connector housings ensure reliable electrical contact for high-speed 10 Gbit/s links.

Suitable for

• Short-range server-to-switch connections within the same rack
• Rack-to-rack links in adjacent cabinets
• Storage area network (SAN) interconnects where 10 Gbit/s is required
• Network closets and top-of-rack switch connections

Key specifications

• Connector type: SFP+ direct-attach
• Data rate: 10 Gbit/s
• Length: 0.5 m
• Media: copper (passive DAC)
• Typical use distance: short-range (within-rack / adjacent racks)
• Compatibility: SFP+ ports supporting direct-attach copper cables

How to use

Ensure both devices have compatible SFP+ ports that support direct-attach copper cables. With devices powered down or in accordance with your equipment vendor’s hot-plug guidance, insert each SFP+ connector into the corresponding SFP+ port until it seats firmly. Route the 0.5 m cable to avoid sharp bends and mechanical strain on the connectors. After installation, verify link status and speed on both devices to confirm a stable 10 Gbit/s connection.

Recommendations

Use this DAC cable for short-distance interconnects where cost, low latency and low power are priorities. Avoid using beyond the intended short-range distances; inspect connectors for damage before installation and handle the cable by the connector housings to protect contacts.
