Twinaxial Direct Attach Cable BlueOptics 10 Gigabit SFP+ 942 280-003 copper

BlueOptics Twinaxial Direct Attach Cable 10 Gigabit SFP+ 942 280-003 copper is a factory-terminated twinax cable designed for short-range, high-speed connections between SFP+ ports. The cable provides a fixed copper link for SFP+ interfaces, offering low latency and low power consumption compared with optical transceivers. It is intended for direct rack-to-rack, server-to-switch, or switch-to-switch connections within data centers and network racks where distances are within the supported copper reach.

Advantages

The direct-attach twinax cable delivers reliable 10 Gigabit performance with minimal signal loss and reduced power use since no separate transceiver modules or optical components are required. As a copper solution it simplifies cabling and lowers total link cost for short-reach connections, while maintaining predictable latency and consistent throughput. The integrated SFP+ plugs ensure plug-and-play compatibility with SFP+-rated ports and enable compact, high-density port deployments in network equipment.

Suitable for

• Rack-to-rack connections inside data center cabinets
• Server uplinks to top-of-rack or leaf switches
• High-density switch interconnects where SFP+ ports are available
• Short-reach links requiring low latency and low power

Key specifications

• Interface: SFP+ on both ends supporting 10 Gigabit Ethernet
• Cable type: Twinaxial copper, factory-terminated
• Performance: 10 Gbps full-duplex
• Typical reach: short-range intra-rack or adjacent-rack distances (copper-reach class)
• Latency: minimal, inherent to direct copper connections
• Power: low power consumption compared with optical transceivers
• Connector form factor: SFP+ direct-attach plug

How to use

Insert each SFP+ plug into the corresponding SFP+ port on the network devices until the latch clicks. Ensure both devices support 10 Gigabit SFP+ direct-attach copper cables and that link settings (speed, duplex, auto-negotiation) are configured consistently on the connected equipment. Use appropriate cable length to avoid excess slack and maintain proper cable routing to prevent stress on connectors. No additional modules or transceivers are required.

Usage recommendations

For reliable operation, verify compatibility with the switch and server vendor documentation for SFP+ direct-attach copper support, keep cable length within the recommended short-reach range for twinax copper, and handle connectors by the housing to avoid damaging the plug or latch. Avoid excessive bending near the connector and maintain proper airflow in racks to prevent overheating of adjacent modules.
