SFP+ Direct Attach Cable BlueOptics SFPP-DAC-2M 10GBASE-CR, 2 m

The BlueOptics SFPP-DAC-2M 10GBASE-CR is a 2 meter SFP+ Direct Attach Cable (DAC) that provides a short-range 10 Gbps copper connection for devices with SFP+ ports. This twinax cable is intended to connect switches, servers and network interface cards directly without requiring separate optical transceivers, offering a compact and cost-effective link for top-of-rack and adjacent-rack connections in data centers and server rooms.

Advantages

The cable offers low latency and low power consumption compared with optical solutions, while simplifying installation by eliminating the need for transceivers. Its fixed 2 m length and SFP+ form factor reduce component count and compatibility issues in dense rack environments. The integrated twinax construction provides stable electrical performance for short-reach 10 Gbps links and is built to meet the electrical specifications of 10GBASE-CR.

Suitable for

• Short-range 10 Gbps links between switches in the same rack or adjacent racks
• Direct connections from servers to top-of-rack switches
• Interconnects between network interface cards and switches in data centers
• Patch and uplink links where optical transceivers are not required

Key specifications

• Interface: SFP+ to SFP+ twinax cable
• Data rate: 10 Gbps (10GBASE-CR compliant)
• Length: 2 meters
• Cable type: Direct attach twinax copper
• Typical use case: Short-reach, rack-to-rack or within-rack connectivity
• Latency: Low electrical latency suitable for server and switch interconnects
• Power: Low power consumption compared with optical transceivers

How to use

Insert each SFP+ connector into the SFP+ port of the devices to be connected, ensuring the latch engages and the cable is seated firmly. Confirm that both ports are configured for 10 Gbps operation and that link status is active on both devices. No additional modules, fiber optic transceivers or patching panels are required; the cable provides a direct electrical connection. When routing the cable, avoid sharp bends and excessive tension to maintain signal integrity and mechanical reliability.

Usage recommendations

Use this 2 m SFP+ DAC for short interconnects in densely populated racks and adjacent racks. Verify compatibility with your switch or server vendor’s supported DAC modules if the equipment enforces vendor checks. Keep the cable length appropriate for the intended topology and follow rack management best practices to prevent strain and maintain airflow.
