BlueOptics SFP-H10GB-CU2M-PA InfiniBand/fibre optic cable 2 m SFP+ Male/Male

The BlueOptics SFP-H10GB-CU2M-PA InfiniBand/fibre optic cable 2 m SFP+ Male/Male is a short-reach copper twinax cable designed for high-speed 10 Gbps links between SFP+ ports. With 2 meters of length and SFP+ male connectors on both ends, this cable provides a straightforward direct-attach solution for switches, servers and storage devices that support SFP+ interfaces. The construction focuses on signal integrity and minimal latency for use in data centres and dense rack installations.

Advantages

This SFP+ twinax cable offers a compact, low-power alternative to optical transceivers and patch cords, eliminating the need for separate modules and fibres. The male/male SFP+ termination ensures plug-and-play compatibility with standard SFP+ ports, while the 2 m length balances reach and cable management in rack environments. Its design reduces transmission latency and supports reliable 10 Gbps connections suitable for short-distance interconnects.

Suitable for

• Direct connections between SFP+ ports on switches, routers and network interface cards
• Server-to-switch links inside data centre racks
• High-speed storage area network (SAN) interconnects at short distances
• Top-of-rack and end-of-row cabling where 2 m reach is sufficient

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 2 meters
• Data rate: up to 10 Gbps
• Cable type: direct-attach twinax (copper)
• Typical application: short-reach InfiniBand and 10 Gigabit Ethernet interconnects
• Low latency design suitable for rack-mounted equipment

How to use

Insert each SFP+ connector firmly into the corresponding SFP+ port on your network devices until the latch engages. Ensure devices are powered down or follow hot-swap guidelines provided by the equipment manufacturer if connecting live. Verify link status via device LEDs or management interfaces and confirm negotiated speed is 10 Gbps. Route the cable to avoid tight bends and mechanical stress; maintain recommended bend radius to preserve signal quality.

Recommendations

Use this 2 m SFP+ twinax cable for short-distance, high-bandwidth links within racks or between adjacent racks. Avoid outdoor use and long runs beyond the specified length; for longer distances, consider active optical cables or fiber-based transceivers. Keep the cable free from sharp bends and secure it to rack framing or cable management panels to reduce strain and maintain long-term reliability.
