BlueOptics InfiniBand/kuitu-kaapeli 20 m QSFP28 akva

The BlueOptics InfiniBand/fibre optic cable 20 m QSFP28 Aqua is a 20 meter active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G data transmission over multimode fiber. It supports 100GBASE-SR4 protocols and is built to meet MSA QSFP28 electrical and mechanical specifications, providing a pre-assembled fiber link for data center and high-performance networking applications where low latency and electromagnetic immunity are required.

Advantages

This QSFP28 AOC offers direct 100 Gbit/s connectivity over 20 m without the need for field termination or patching, reducing installation time and link losses. The cable integrates transmitters and receivers on each end and includes Digital Diagnostic Monitoring (DDM/DOM) capability for real-time monitoring of supply voltage, laser bias current, transmit output power, receive input power and temperature when supported by the host. Components are selected to meet MSA requirements and industrial standards to ensure consistent interoperability and long operational life.

Suitable for

• Data center top-of-rack and spine switch interconnects
• High-performance computing (HPC) clusters using InfiniBand or 100G Ethernet
• Storage systems and SAN interconnects requiring 100G links
• Network equipment testing and temporary high-speed link deployments

Key specifications

• Connector type: QSFP28 to QSFP28
• Length: 20 meters
• Data rate: up to 100 Gbit/s (100GBASE-SR4 capable)
• Fiber type: multimode fiber with integrated optical transceivers
• Monitoring: Digital Diagnostic Monitoring / Digital Optical Monitoring (DDM/DOM) compliant with SFF-8472 when supported by host
• MSA compliance: QSFP28 AOC electrical, mechanical and functional alignment
• Immunity: not susceptible to electromagnetic interference (fiber-optic link)
• Standards compliance: CE and RoHS (where applicable)

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on networking devices, ensuring proper alignment and a secure latch. No field splicing or fiber polishing is required; the pre-assembled cable provides a plug-and-play optical connection. If DDM/DOM information is required, verify that the host hardware supports reading the diagnostic registers and monitor the parameters through the device management interface. Handle the cable by the connector housings and avoid tight bends to preserve multimode fiber performance.

Recommendations

Use the cable in equipment that officially supports QSFP28 AOC modules and the 100GBASE-SR4 transmission protocol. Maintain minimum bend radius as specified by the manufacturer, keep connectors clean and store the cable on a spool or protective packaging when not in use to preserve optical performance.
