CBO DAC Cable 10Gbps 5m — CBO Tyco TE Connectivity 2127934-4 direct-attach copper

CBO DAC Cable 10Gbps 5m — CBO Tyco TE Connectivity 2127934-4 direct-attach copper is a 5-metre direct-attach copper (DAC) cable designed for short-reach high-speed links. The assembly supports data rates up to 10Gbps and is intended for point-to-point wired connections between networking equipment such as switches, routers and servers. The cable provides a direct electrical connection without optical transceivers, offering low latency and a cost-effective option for data centre rack-to-rack cabling where fibre is not required.

Advantages

This DAC cable delivers a reliable, low-latency 10Gbps connection over a fixed 5 m length. As a direct-attach copper solution it eliminates the need for separate transceivers, reducing power consumption and component count in the rack. The pre-terminated assembly simplifies installation and replacement in dense rack environments, while compatibility with standard 10 Gigabit interfaces makes it suitable for common networking topologies. The product is produced under the CBO BlueOptics line and utilises the Tyco TE Connectivity 2127934-4 specification for consistent performance.

Suitable for

• Short-reach connections between switches and routers in a rack
• Server-to-switch uplinks in data centre cabinets
• Top-of-rack to aggregation layer links within the same room
• Environments where low latency and cost-effective wired links are required

Key specifications

• Cable type: direct-attach copper (DAC)
• Maximum supported data rate: 10 Gbps
• Length: 5 metres
• Connector style: direct-attach assembly for 10 Gigabit interfaces
• Typical application: short-reach rack-to-rack and switch-to-server links

How to use

Install the CBO DAC Cable by inserting each end into the corresponding 10 Gigabit ports on your networking devices until the connectors engage. Ensure devices are powered down or ports are in a hot-pluggable state according to the equipment manufacturer’s guidance if required. Verify link status and negotiated speed in the device management interface after connection. Use appropriate cable routing to avoid sharp bends or compression that could stress the assembly.

Usage recommendations

For reliable operation, use this direct-attach copper cable within its 5 m length limit and avoid extended exposure to mechanical strain or tight bend radii. Confirm that connected devices support 10Gbps DAC assemblies and consult equipment documentation for any interface compatibility notes. Store and handle the cable according to standard data centre cabling practices to maintain performance.
