BlueOptics MFA1A00-C025-BO InfiniBand fibre optic cable 25 m QSFP28

The BlueOptics MFA1A00-C025-BO InfiniBand fibre optic cable 25 m QSFP28 is a 25‑meter active optical cable (AOC) with QSFP28 to QSFP28 male connectors designed for high-speed interconnects in data centres and HPC environments. It implements a multi‑mode optical link with integrated transmitter and receiver modules on each end to deliver serial data rates suitable for 100GBASE‑SR4 and compatible InfiniBand applications over 25 metres. The cable follows QSFP28 form‑factor mechanical and electrical conventions to ensure plug‑and‑play compatibility with ports that support QSFP28 AOCs under the same industry MSA guidelines.

Advantages

This BlueOptics 25 m QSFP28 AOC provides a compact, lightweight alternative to copper and discrete transceiver plus fibre assemblies, reducing rack clutter and improving airflow in dense installations. The integrated transceiver electronics lower host port power management complexity while enabling reliable high‑speed signalling up to 100 Gbit/s over multi‑mode fibre. Compatibility with platforms that accept QSFP28 AOCs minimizes integration effort and simplifies high‑bandwidth link deployment between switches, routers and storage nodes.

Suitable for

• High‑performance computing clusters and inter‑node links
• Data centre switch‑to‑switch and switch‑to‑server connections
• Storage area networks and high‑throughput storage appliances
• InfiniBand fabric links and 100G Ethernet short‑reach connections

Key specifications

• Cable type: Active Optical Cable (AOC) with multi‑mode fibre
• Connector type: QSFP28 male to QSFP28 male
• Length: 25 metres
• Supported data rates: up to 100 Gbit/s (SR4 profile compatible)
• Form factor: QSFP28 pluggable AOC
• Typical use: short‑reach server, switch and storage interconnects

How to use

Insert the QSFP28 plugs into compatible QSFP28 host ports until the latches engage; no separate transceiver or fibre termination is required. Ensure both ends are connected to equipment that supports QSFP28 AOCs and that the devices are configured for the intended protocol (100G Ethernet, InfiniBand or Fibre Channel over Ethernet). Handle the cable by the connector housings and avoid sharp bends; observe standard ESD precautions when inserting or removing the connectors. Power up and verify link status on the connected equipment and check interface counters for error‑free operation.

Recommendations

For reliable operation, route the 25 m AOC with gentle bend radii and avoid kinking or compressing the cable. Use in environments that accept multi‑mode, short‑reach optical links and confirm host compatibility with QSFP28 active optical cables. If interoperability with specific vendor hardware is critical, validate the link in a lab or request a sample for compatibility testing prior to large deployments.
