CBO DAC SFP+ passive direct attach copper cable 1 m model DAC-1M-BL

The CBO DAC SFP+ passive direct attach copper cable 1 m model DAC-1M-BL is a factory-terminated 1-metre copper interconnect designed for short-reach 10 Gigabit Ethernet links between SFP+ ports. This passive SFP+ cable provides a direct electrical connection for switches, servers and storage systems without separate optical transceivers, offering low latency and consistent physical-layer performance for rack-to-rack and intra-rack connections in data centres and network closets.

Advantages

This passive SFP+ DAC cable delivers reliable 10GbE connectivity with minimal signal conversion overhead and lower power consumption compared with active optics. The fixed 1 m length simplifies cable management in dense rack environments and reduces component count by eliminating separate modules. Its factory termination ensures compatibility with standard SFP+ ports and predictable electrical characteristics for short-reach links.

Key specifications

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure devices are powered down or ports prepared according to vendor recommendations before insertion or removal if required by the host. After physical installation, verify link status and speed on both devices and adjust port configuration in the network operating system as needed for 10GbE operation.

Recommendations

Use this 1 m passive DAC where short, fixed-length connections are suitable and device vendors support passive SFP+ direct-attach copper; avoid using beyond the recommended distance for passive twinax to maintain signal integrity. Keep the cable free from sharp bends and secure it to avoid strain on the connectors.
