BlueOptics Q28-AOC-25M-SP-BO InfiniBand optický kábel 25 m QSFP28

The BlueOptics Q28-AOC-25M-SP-BO InfiniBand fibre optic cable 25m QSFP28 is a 25-metre active optical cable (AOC) designed for short-reach 100G connections between devices within racks or between adjacent racks. It uses QSFP28 to QSFP28 connectors with integrated electrical-to-optical and optical-to-electrical conversion, OM3 multimode fibre with a 50 µm core and LSZH (low smoke zero halogen) flame-resistant sheathing. The cable conforms to common MSA, SFF and IEEE connector specifications and is intended for high-speed data centre and networking environments.

Advantages

The AOC design provides reduced weight and greater flexibility compared with direct-attach twinax cables while delivering the same 100GBASE-SR4 capability over short distances. Built-in transceiver electronics in the QSFP28 connectors convert signals between electrical and optical domains, enabling hot-pluggable operation. The OM3 multimode fibre and small bend radius support stable high-bandwidth performance. LSZH sheathing reduces hazardous emissions in case of fire. Each cable is factory new and tested for functionality and quality prior to dispatch.

Suitable for

• 100G Ethernet links inside racks and between adjacent racks
• InfiniBand high-speed interconnects for servers and switches
• Data centre uplinks, spine-leaf topologies and switch-to-switch connections
• High-density networking environments requiring hot-pluggable interconnects

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Length: 25 metres
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm
• Designed data rate: 100G (100GBASE-SR4 compatible)
• Sheathing: LSZH (low smoke, zero halogen), flame resistant
• Bend radius: reduced/smaller than typical DAC solutions (improved flexibility)

How to use

Install the cable by inserting each QSFP28 connector into compatible QSFP28 ports on switches, network interface cards or other compatible devices. Ensure ports are powered down or follow hot-plug guidance from your hardware vendor if connecting live. Route the cable to avoid excessive bending beyond the recommended bend radius and secure it to prevent strain on connectors. After connection, verify link status and speed on the connected devices and run any required diagnostics or link training procedures recommended by your equipment manufacturer.

Recommendations

Use this BlueOptics QSFP28 AOC for short-range 100G links where reduced weight, improved flexibility and hot-pluggability are required. Avoid tight bends and physical stress on the connector area, keep the LSZH sheath free of oil or abrasive contamination, and follow your hardware vendor’s guidance for hot-plug operation and link diagnostics to ensure reliable performance.
