BlueOptics Q28-AOC-3M-SO-BO InfiniBand/optický kabel 3m QSFP28 samec/samec

The BlueOptics Q28-AOC-3M-SO-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3‑metre active optical cable designed for high-density, high-throughput network environments. It connects QSFP28 ports on switches, servers and adapters to deliver low-latency, high-bandwidth links suitable for 100 Gigabit Ethernet and InfiniBand HDR environments. The cable assembly combines QSFP28 male connectors on both ends with an optical active link to minimize electrical interference and support reliable data transmission over a 3 m span.

Advantages

This QSFP28 active optical cable provides high data rates and low power consumption compared with equivalent copper assemblies. Its optical design reduces susceptibility to electromagnetic interference and crosstalk, while the fixed 3 m length simplifies cable management in racks and enclosures. The cable supports long-term stable performance for continuous data centre operations and is compatible with equipment that accepts QSFP28 form-factor modules.

Suitable for

• Interconnecting QSFP28 ports in data centre switches and routers
• Linking high-performance computing nodes in InfiniBand clusters
• Direct server-to-switch connections requiring 100 Gbit/s or equivalent throughput
• Short-range optical links within server racks and network cabinets

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Supported protocols: 100 Gigabit Ethernet, InfiniBand (HDR/EDR rates depending on system compatibility)
• Transmission medium: Multi-channel optical fibre within AOC assembly
• Typical latency: Low, suitable for low-latency network requirements
• Operating environment: Data centre and server room use

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port until the connector latches or seats securely; do not force the plug. Verify that connected devices recognise the link and negotiate the expected speed and link parameters. Route the 3 m cable to avoid tight bends and excessive tension; maintain the minimum bend radius specified by the device manufacturer. For hot-pluggable systems, insert or remove the cable with the host and peer devices powered on only if the equipment supports hot-swap operations.

Recommendations

Handle connectors by their housing and keep connector ends protected from dust. Avoid kinking the cable and maintain proper rack management to prevent strain. Confirm compatibility with your switch or adapter vendor for supported link modes and firmware interoperability before deployment.
