InfiniBand optický kabel BlueOptics XDL-TWX0301-BL 3 m SFP+

The BlueOptics XDL-TWX0301-BL InfiniBand fibre optic cable 3 m SFP+ is a 3-metre high-speed connection cable with SFP+ connectors on both ends, designed for short-range links in racks and adjacent rack rows. It supports 10 Gbit/s-class data transmission and is suitable for use where low latency and reliable signal integrity are required. The cable features a robust construction intended for professional networking and data centre environments and can be used as a direct-attach solution for compatible InfiniBand and 10GBase-CR hardware.

Advantages

The cable provides stable 10G data transfer over a 3 m distance with low latency and low power requirements typical for passive twinax/Direct Attach type connections. Its build quality and compliance with established MSA standards ensure broad compatibility with switches, routers and storage systems that accept SFP+ direct-attach cabling. The passive design reduces failure points and power consumption while offering a cost-effective alternative to active transceiver-based links.

Suitable for

• Short-range interconnects inside racks and between adjacent racks in data centres
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand links that accept SFP+ direct-attach cables
• Connections between switches, routers, storage systems and servers with SFP+ ports

Key specifications

• Length: 3 metres
• Connector type: SFP+ to SFP+
• Supported data rate: up to 10 Gbit/s
• Cable type: passive direct-attach twinax (low-power passive copper solution)
• Wire gauge: 30 AWG
• MSA-compliant mechanical and electrical characteristics

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be linked, ensuring the connectors are fully seated and the latches engage. Use the cable for short-distance links up to 3 m between compatible switches, routers, servers or storage systems. Confirm that the target hardware supports passive 10GBase-CR/direct-attach twinax cabling and that firmware or vendor settings permit third-party passive SFP+ cables when applicable. No separate power or configuration is required for the cable itself.

Recommendations

For reliable operation, keep the cable run within the specified 3 m length and avoid sharp bends or crushing; maintain a bend radius consistent with 30 AWG twinax construction. Verify device compatibility and, when possible, test a sample link during initial deployment to ensure full functionality with vendor equipment and firmware versions.
