BlueOptics InfiniBand/fibre optic cable 7 m QSFP28 Turquoise

The BlueOptics InfiniBand/fibre optic cable 7 m QSFP28 Turquoise is a 7-metre high-density active optical cable designed for high-speed data transmission in data centres and networking environments. Equipped with QSFP28 male-to-male connectors, this cable supports short-range links between QSFP28 ports on switches, servers and network adapters. Its turquoise jacket and compact form factor are typical for QSFP28 optical links and help with quick visual identification in structured cabling setups.

Advantages

This QSFP28 fibre optic cable offers low-latency, high-bandwidth connectivity suitable for InfiniBand and Ethernet environments. The QSFP28 connectors provide reliable mechanical mating and stable signal integrity for 100 Gbps-class links when used with compatible QSFP28 ports. The 7 m length provides flexibility for rack-to-rack or within-rack connections while maintaining signal performance expected from short-reach optical interconnects.

Suitable for

• Short-range interconnects in data centres between switches, servers and storage systems
• High-performance computing clusters using InfiniBand or 100GbE QSFP28 ports
• Structured cabling where a 7 m QSFP28 link is required for rack connectivity

Key specifications

• Connector type: QSFP28 male-to-male
• Length: 7 metres
• Cable type: fibre optic / active optical cable suitable for short-reach high-speed links
• Colour: turquoise jacket for visual identification
• Application: compatible with InfiniBand and 100GbE ports supporting QSFP28 interfaces

How to use

Install the cable by inserting each QSFP28 connector into the appropriate QSFP28 port until the connector latches. Verify that both ends are inserted into compatible QSFP28 ports on switches, servers or network adapters configured for the intended protocol (InfiniBand or Ethernet). After physical installation, check link status LEDs or management interfaces to confirm link establishment and negotiate speed and lane configuration according to the connected devices.

Recommendations

Route the cable to avoid tight bends and maintain the manufacturer’s minimum bend radius to preserve optical performance. Use labelled cable management paths in rack environments and ensure both connected devices support QSFP28 optical links and the expected data-rate configuration before deployment.
