## Long description

The BlueOptics InfiniBand/fibre optic cable 3 m QSFP28 Turquoise is a 3-metre direct-attach optical cable designed for high-speed connectivity in data centres and enterprise networking environments. It uses QSFP28 connectors to support high-bandwidth, low-latency links between switches, servers and storage systems. The cable is manufactured for stable signal transmission over short to medium distances and features a turquoise jacket for easy identification in cabling runs.
Advantages
This QSFP28 fibre optic cable provides a compact, low-power solution for high-throughput links, reducing the space and airflow impact compared with active transceiver modules. It offers consistent performance for InfiniBand and compatible Ethernet or Fibre Channel applications, with male-to-male QSFP28 terminations that simplify direct connections between networking equipment. The turquoise colour helps with visual organisation of cable infrastructure and the 3 m length balances reach and signal integrity for rack-to-rack or within-rack interconnects.
Suitable for (tasks / use cases)
High-performance compute clusters requiring InfiniBand connectivity
Server-to-switch or switch-to-switch interconnects in data centres
Low-latency storage networking and SAN links
Cable management where colour-coded identification is used
Short to mid-range optical links up to 3 metres within racks
Key specifications
Cable type: Direct-attach fibre optic cable with QSFP28 connectors
Length: 3 metres
Connector configuration: Male-to-male QSFP28
Supported protocols: InfiniBand and compatible high-speed Ethernet/Fibre Channel links
Jacket colour: Turquoise for easy identification
Intended use: Short to medium-range high-bandwidth, low-latency links
How to use
Align each QSFP28 connector with the corresponding QSFP28 port on your networking equipment and insert until the latch engages. Ensure both ends are fully seated and that devices are powered down or follow hot-plug procedures recommended by the equipment manufacturer when connecting live. Route the cable to avoid sharp bends and excessive strain; maintain the recommended minimum bend radius. Verify link status through device LEDs or management interfaces after connection to confirm proper operation.
Usage recommendations
For reliable long-term performance, avoid tight twisting and keep slack loops to reduce stress on connectors. Use colour-coded cabling practices to simplify maintenance and troubleshooting in dense rack environments. Follow equipment vendor guidelines for supported cable types and maximum supported reach for QSFP28 direct-attach fibre links.
