SFP+ direct attach copper cable CBO SFP-DAC10-BL 1 m 10 Gbit/s

The SFP+ direct attach copper cable CBO SFP-DAC10-BL 1 m is a passive twinax cable designed to provide a 10 Gbit/s electrical connection between devices equipped with compatible SFP+ ports. With a 1 meter length, this cable is intended for short-range, high-speed interconnects such as within-rack or adjacent-rack connections between switches, routers and servers. The passive electrical design offers low latency and lower power consumption compared with active copper or optical transceivers while delivering plug-and-play operation for straightforward installation.

Advantages

The cable supports 10 Gbit/s data rates with minimal signal conversion, which reduces latency and power draw. Its short, fixed-length twinax construction provides a reliable, low-cost alternative to fiber optics for distances within a rack or between nearby racks. The fit is compatible with standard SFP+ ports for simple insertion and removal, and the passive design eliminates the need for additional power or optical transceivers.

Suitable for

• Short-range high-speed links between switches in the same rack
• Connections from servers to top-of-rack or leaf switches
• Patch and interconnect cabling in dense rack environments
• Environments where low latency and reduced power consumption are priorities

Key specifications

• Data rate: 10 Gbit/s
• Length: 1 m
• Connector type: SFP+ compatible twinax direct attach copper
• Design: Passive (no external power)
• Typical use range: short-range / within-rack or adjacent-rack
• Latency: low (electrical direct attach link)

How to use

Insert each SFP+ connector end into the corresponding SFP+ port on the devices to be connected until the retention latch engages. Ensure both devices are powered and configured to operate at 10 Gbit/s where necessary. No additional drivers or transceivers are required for basic connectivity; the link should appear to the network OS as a standard 10 Gbit/s interface. Remove the cable by depressing the latch and pulling the connector straight out to avoid damaging the port.

Recommendations

Use the 1 m passive DAC for short, direct connections inside racks or between adjacent racks; avoid using it for longer distances where signal integrity would require active cabling or optical transceivers. Verify compatibility with device SFP+ port specifications and, if using in dense patching scenarios, route cables to avoid sharp bends and excessive strain on connectors.
