SFP+ Direct Attach Cable BlueOptics iSFP-10G-C5M-BL 10GBASE-CR, 5 m, passive

SFP+ Direct Attach Cable BlueOptics iSFP-10G-C5M-BL 10GBASE-CR, 5 m, passive is a 5‑metre passive copper twinax assembly engineered for direct 10 Gbps connections between SFP+ ports. It implements the 10GBASE‑CR electrical specification and is intended for short‑reach links in server, switch and storage environments where a compact, low‑latency copper solution is preferred over optical transceivers and fiber cabling.

Advantages

The passive twinax design provides low latency and deterministic performance by avoiding optical conversion. Its fixed 5 m length simplifies cable management in top‑of‑rack and rack‑to‑rack deployments and reduces power consumption compared with active optical solutions. The cable is compatible with standard SFP+ ports, offering a cost‑effective option for high‑density data center patching and direct server-to-switch connections without the need for separate transceivers.

Suitable for

• Short‑reach 10 Gbps interconnects between servers and switches
• Top‑of‑rack and rack‑to‑rack connections in data centers
• Direct attach links for storage arrays and blade enclosures
• Environments where low latency and reduced power usage are important

Key specifications

• Interface: SFP+ electrical plug‑to‑plug
• Data rate: 10 Gbps (10GBASE‑CR compatible)
• Length: 5 metres
• Cable type: Passive copper twinax
• Typical use: Short‑reach direct attach links
• Latency: negligible added latency compared with optical conversion

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices ensuring they are fully seated and the retention latches engage. Confirm that the connected devices are configured for 10 Gbps operation and that any port settings (speed, duplex, auto‑negotiation) match the intended use. No external power or transceivers are required; the cable functions as a direct electrical link once properly connected.

Usage recommendations

Route the cable to avoid sharp bends and excessive mechanical stress; maintain the manufacturer’s minimum bend radius. Use this passive 5 m twinax for short‑reach links only — for longer distances or optical isolation, choose fiber with appropriate transceivers. Verify compatibility with vendor switch and server port firmware when deploying at scale.
