Direct Attach Cable (DAC) CBO 0231A0AM-3C SFP+ copper 30 m

CBO DAC 0231A0AM-3C SFP+ copper 30 m is a 30-metre Direct Attach Cable (DAC) from BlueOptics designed for short-range 10 Gb/s connections between SFP+ ports. The fixed-length copper assembly provides a straightforward, low-latency physical link for switches, routers and servers in rack and data centre environments where a reliable copper interconnect is required. It supports standard SFP+ interfaces and is intended for point-to-point connections without additional transceivers.

Advantages

The Direct Attach Cable offers a cost-effective alternative to optical transceivers for short-range links, reducing total connection cost and power consumption. The fixed 30 m length simplifies cable management and planning, while the copper medium delivers low latency and consistent signal integrity for 10 Gb/s traffic. Compatibility with standard SFP+ ports ensures easy installation and interoperability with common networking equipment.

Suitable for

• Short-range 10 Gb/s links between SFP+ ports on switches and routers
• Server-to-switch connections within racks or across adjacent racks
• Data centre interconnects where cost and power efficiency are priorities
• Environments that require low-latency, high-throughput copper links

Key specifications

• Cable type: Direct Attach Copper (DAC)
• Connector type: SFP+ compatible plug-to-plug
• Length: 30 metres
• Nominal data rate: 10 Gb/s
• Intended use: short-reach, point-to-point connections
• Medium: copper twinax construction for reduced interference
• Power consumption: lower than equivalent optical transceiver plus fibre

How to use

Install the DAC by inserting each SFP+ plug into the corresponding SFP+ port on your networking devices until the latch engages. Ensure devices are powered down or follow hot-swap guidelines from the equipment manufacturer if plugging into live ports. Verify link status and speed in the device management interface and confirm that the connection operates at 10 Gb/s. Route the cable to avoid sharp bends and sources of electromagnetic interference; the fixed-length assembly does not require separate transceivers.

Recommendations

For reliable operation, use the DAC for connections within the specified 30 m range and pair it with equipment that supports SFP+ interfaces. Avoid kinking or tightly bending the cable, and keep it away from high-power electrical cables to minimise interference. Check device compatibility lists when integrating into heterogeneous environments to ensure optimal performance.
