SFP+ Copper Twinax Cable BlueOptics SFP-H10GB-CU2M-LE-BL 2 m Male-to-Male 10 Gbit/s

The BlueOptics SFP+ CBO SFP-H10GB-CU2M-LE-BL 2m Male/Male 10Gbit/s is a copper direct attach cable assembly designed for 10 Gigabit Ethernet connections. It provides a fixed, cost-effective 2-meter twinax copper link with SFP+ male connectors on both ends, compatible with SFP+ ports that accept copper DAC modules. The cable is intended for short-reach, high-speed interconnects between switches, servers and network interface cards where fiber optics are not required.

Advantages

This SFP+ DAC offers low latency, minimal power consumption and straightforward plug-and-play operation without the need for external transceivers or optical components. The 2 m length balances flexibility and signal integrity for rack-to-rack or in-rack connections. Constructed for compatibility with standard SFP+ form-factor ports, the cable reduces installation complexity and ongoing maintenance compared with active optical solutions.

Suitable for

• Rack-to-rack 10 Gigabit Ethernet links in data centers
• Server to switch or NIC to switch connections in enterprise networks
• Short-reach connections inside cabinets and network racks
• Environments where low latency and low power are priorities

Key specifications

• Interface: SFP+ male connectors on both ends
• Data rate: 10 Gbit/s
• Cable type: Twinax copper direct attach (DAC)
• Length: 2 metres
• Configuration: Passive copper assembly for short-reach

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your networking devices until the retention latch engages. Ensure both devices are powered and configured for 10 Gbit/s operation. No additional drivers or optical transceivers are required. Verify link status on the devices' management interfaces and, if necessary, adjust port settings such as speed and duplex to match network requirements.

Recommendations

Maintain a secure, strain-relieved routing path within racks to avoid cable stress and excessive bending; avoid sharp bends and keep the cable away from sources of electromagnetic interference. For best results, use this 2 m passive DAC for short, direct connections inside a rack or between adjacent racks and confirm device compatibility with SFP+ copper modules before deployment.
