BlueOptics UACC-AOC-QSFP28-20M-BO InfiniBand fibre optic cable 20m Male/Male

The BlueOptics UACC-AOC-QSFP28-20M-BO InfiniBand fibre optic cable 20m Male/Male is a 20-metre active optical cable (AOC) with QSFP28 connectors designed for high-speed links in data centre and networking environments. The cable implements QSFP28-to-QSFP28 connectivity and supports 100G-class short-reach multi-mode transmission over a 20 m length. It is intended for direct connection between compatible QSFP28 ports and for use where a reliable, compact active optical link is required.

Advantages

This active optical cable delivers high-bandwidth 100G-capable links with low latency and reduced electromagnetic susceptibility compared with copper alternatives. The QSFP28 male-to-male configuration simplifies direct port-to-port connections without transceivers. Designed to comply with common MSA standards, the cable is built for consistent optical performance over its 20 m length and for operation in typical data centre and networking deployments.

Suitable for

• Interconnecting QSFP28 ports on switches and routers within racks and between adjacent racks
• High-speed server-to-switch or switch-to-switch links in data centres
• Short-reach InfiniBand or Ethernet 100G links over multi-mode fibre

Key specifications

• Type: Active Optical Cable (AOC) with QSFP28 connectors
• Length: 20 metres
• Connector configuration: Male to Male (QSFP28 to QSFP28)
• Supported protocol classes: 100G multi-mode short-reach (e.g. 100GBASE-SR4, InfiniBand or similar high-speed links)
• Cable medium: Multi-mode fibre with integrated transmitter and receiver at each end

How to use

Insert the QSFP28 connector into the corresponding QSFP28 port on each device until the connector latches. Ensure devices are powered off or follow hot-plug guidelines of the hardware vendor when inserting or removing the cable. Verify link status through the host devices' management interfaces or LEDs and configure the interfaces according to the required protocol (Ethernet, InfiniBand, etc.). Use cable management to avoid sharp bends and maintain the recommended minimum bend radius for multi-mode fibre assemblies.

Usage recommendations

Inspect connectors before use and keep protective caps on when not connected. Avoid tight bends, crushing, or exposure to excessive heat. For best interoperability, ensure connected devices officially support QSFP28 AOC links of this type and check firmware or compatibility notes from the device vendor if needed.
