SFP+ DAC cable CBO MCP2103-X003B 30 m Passive

The BlueOptics SFP+ DAC cable CBO MCP2103-X003B 30 m Passive is a direct attach copper cable designed for 10 Gigabit Ethernet and InfiniBand links. With SFP+ form-factor connectors at both ends, this 30-metre passive cable enables a low-latency, point-to-point connection between switches, servers and storage systems without the need for additional transceivers. It is intended for short- to mid-range rack-to-rack and intra-rack installations where cost-efficiency and straightforward plug-and-play operation are required.

Advantages

The passive construction reduces power consumption compared with active optical solutions and removes the need for external power or signal conditioning. Plug-and-play SFP+ connectors provide simple installation and immediate recognition by compatible network ports. The copper medium offers consistently low latency and stable performance for high-throughput environments, while the 30 m length covers typical data centre rack-to-rack distances without intermediate equipment.

Suitable for

• 10 Gigabit Ethernet connections between network switches
• Direct server-to-switch or server-to-storage links
• Intra-rack and short rack-to-rack data centre cabling
• InfiniBand links in high-performance computing racks

Key specifications

• Connector type: SFP+ plug on both ends
• Media: passive copper direct attach
• Maximum supported data rate: 10 Gbps per lane
• Nominal length: 30 metres
• Typical application: 10G Ethernet, InfiniBand
• Latency profile: low, suitable for latency-sensitive traffic

How to use

Insert the SFP+ connector plugs into compatible SFP+ ports on each device until they click into place. Ensure both devices are powered and their interfaces are configured for 10 Gigabit operation if required by your network settings. No external power or transceiver modules are needed for passive operation. Verify link status through device LEDs or management interfaces and perform standard network tests to confirm throughput and stability.

Recommendations

Use the cable within rack and between adjacent racks where distances do not exceed 30 m. Avoid tight bending near the connector ends and maintain a minimum bend radius consistent with copper DAC handling to prevent mechanical stress. Ensure compatibility with device vendors' SFP+ ports and firmware; consult switch/server documentation if link negotiation issues occur.
