## Summary description

The BlueOptics XEN-TWX-0511-BL is a 5 m InfiniBand/fibre optic cable featuring SFP+ connectors. It ensures high-speed data transmission and reliable connectivity for networking applications.

## Long description

The BlueOptics XEN-TWX-0511-BL InfiniBand/fibre optic cable 5 m SFP+ Black is a 5-metre direct attach solution with SFP+ connectors designed for high-speed links in rack and adjacent-rack environments. It supports up to 10 Gbit/s data rates and is suitable for short-distance electrical twinax connections where the SFP+ form factor is required. The cable is MSA-compliant and intended for use with hardware platforms that accept SFP+ passive direct attach twinax cables.
Advantages
This 5 m SFP+ twinax cable provides reliable high-speed connectivity with low latency and low power consumption typical of passive direct attach copper solutions. Manufactured with MSA-compliant components and tested for compatibility, it offers consistent performance for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s over the specified length. The passive design reduces complexity and failure points compared with active transceiver solutions.
Suitable for
 Short-range 10 Gbit/s links between switches and servers in racks
 Direct connections between adjacent rack hardware (switch-to-switch, switch-to-storage)
 Environments requiring SFP+ connectivity for Ethernet, FCoE or InfiniBand
 Data center top-of-rack cabling where low latency and low power are priorities
Key specifications
 Connector type: SFP+ to SFP+
 Cable length: 5 metres
 Transmission medium: twinax copper (passive)
 Supported data rate: up to 10 Gbit/s
 Wire gauge: 26 AWG
 Form factor compliance: MSA-compliant SFP+ interface
 Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand
How to use
Install the cable by inserting each SFP+ connector into the SFP+ slot of the corresponding devices until the connector latch engages. Use the 5 m length for direct connections within or between adjacent racks; ensure both devices support passive SFP+ twinax DACs and the targeted protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). Verify link status through the devices' management interfaces after connection and route cabling to avoid sharp bends or excessive mechanical strain on the connectors.
Usage recommendations
For reliable operation, confirm device compatibility with passive SFP+ twinax cables before deployment, avoid tight cable bends and secure the cable to prevent strain on the SFP+ connectors. Use this 5 m cable for short-distance links where cost-efficiency, low latency and low power consumption are required.
