## Summary description

The BlueOptics OS6860-CBL-300-BL is a 3m InfiniBand fibre optic cable featuring QSFP connectors on both ends. It provides high-speed data transfer and reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics OS6860-CBL-300-BL InfiniBand Fibre Optic Cable 3m QSFP Male/Male is a 3 metre connection solution designed for high-speed links in data centres and high-performance computing environments. Featuring QSFP connectors on both ends, it supports up to 40G data rates for short-range connections and is intended for use where reliable, low-latency interconnects are required. The cable is compatible with equipment that supports QSFP-to-QSFP direct attach connections and follows industry MSA guidelines for physical and electrical characteristics.
Advantages
This BlueOptics cable provides stable high-bandwidth transmission with low latency suitable for switching, storage and computing racks. As a direct-attach twinax solution in a 3 m length it offers simple installation, low power consumption and a low failure rate due to its passive design. The product is manufactured from industry-grade components to ensure consistent signal integrity and long operational lifetime.
Suitable for
 40G InfiniBand and Ethernet short-reach interconnects
 Connections between switches, routers and storage systems within or between adjacent racks
 High-performance computing clusters and data centre uplinks
 Environments requiring low-latency, low-power direct-attach links
Key specifications
 Connector type: QSFP male to QSFP male
 Length: 3 metres
 Supported data rate: up to 40 Gbps
 Cable type: direct-attach twinax (passive) suitable for short distances
 Wire gauge: 30 AWG
 Standards: MSA-compliant mechanical and electrical characteristics
 Typical power consumption: very low (passive design)
How to use
Install the cable by plugging each QSFP connector firmly into the corresponding QSFP port on the network devices, ensuring connectors are aligned and fully seated. Use the 3 m length to link hardware within the same rack or between adjacent racks; verify that the connected devices support passive QSFP direct-attach twinax cables and the required 40G protocols (Ethernet, FCoE, Fibre Channel or InfiniBand). Avoid excessive bending and mechanical stress on the cable, and confirm link status through device diagnostics after installation.
Usage recommendations
For reliable operation, confirm device compatibility with QSFP passive direct-attach twinax cables and keep cable bend radius within manufacturer guidelines. Use in short-distance connections (up to 3 m) inside racks or between adjacent racks; avoid deploying passive DACs over longer distances where active or optical modules are required.
