Direct Attach Copper (DAC) Cable CBO 2053649-1 SFP+ 10Gbps 1.8m

BlueOptics Direct Attach Copper (DAC) Cable CBO 2053649-1 SFP+ 10Gbps 1.8m is a fixed-length twinax copper cable with SFP+ connectors engineered for short-range, high-speed interconnects. The cable supports 10 Gbps data rates and is intended for direct attachment between switches, servers and storage devices in rack-to-rack or top-of-rack setups. As a passive twinax assembly, it eliminates the need for separate optical transceivers and provides a low-latency, energy-efficient physical link for immediate deployment in data centers and network closets.

Advantages

The DAC design delivers low power consumption and minimal latency compared with optical transceiver solutions, while offering a cost-effective option for short-distance connections. Its fixed 1.8 m length and integrated SFP+ connectors simplify installation and inventory management. The copper twinax construction ensures predictable electrical performance and reliable signal integrity for 10 Gbps links in typical rack environments.

Suitable for

• Server-to-switch and switch-to-switch connections within the same rack or adjacent racks
• Top-of-rack (ToR) deployments requiring a fixed copper link
• Storage array interconnects and short-range uplinks in data centers

Key specifications

• Connector type: SFP+ to SFP+
• Data rate: 10 Gbps
• Length: 1.8 m (fixed)
• Cable type: Twinax direct attach copper (passive)
• Latency: low, suitable for intra-rack links
• Power profile: low power compared with optical transceivers

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the network equipment until the latch engages. Ensure both ports are powered and configured for 10 Gbps operation in the device firmware or operating system. For best results, route the cable to avoid sharp bends and reduce mechanical strain on the connectors. No additional transceivers or external power sources are required; the assembly functions as a direct electrical connection between SFP+ ports.

Recommendations

Use this 1.8 m DAC cable for short-distance links within racks or between adjacent racks where a fixed-length, low-latency copper connection is preferred. Avoid installation in environments that exceed recommended bend radii or expose the cable to physical stress. Verify compatibility with device SFP+ port vendor interoperability lists when mix-and-match deployments are planned.
