Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-25M-BC-BO 25 m OM3

The BlueOptics Q28-AOC-25M-BC-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) designed for 100G high-speed transmissions over short distances. It uses QSFP28 to QSFP28 connectors with built-in electrical/optical conversion and OM3 multimode fibre with a 50 µm core diameter. The 25 meter length and LSZH (low smoke zero halogen) sheath make it suitable for intra-rack and inter-rack connections in data centres and high-performance computing environments where high bandwidth and reduced weight are required.

Advantages

This QSFP28 to QSFP28 AOC provides full 100GBASE-SR4 compatibility and offers lower weight and greater flexibility compared with direct attach twinax (DAC) cables. The integrated transceiver modules follow MSA, SFF and IEEE specifications for interoperability, and the smaller bend radius and reduced diameter improve cable routing in dense installations. The LSZH outer jacket reduces toxic gases and smoke in the event of fire. Each cable is factory-new and tested for quality and functionality before shipment.

Suitable for

• High-density data centre rack-to-rack connections
• Server-to-switch and switch-to-switch 100G links
• High-performance computing clusters and InfiniBand fabrics
• Short-reach 100GBASE-SR4 Ethernet applications

Key specifications

• Connector type: QSFP28 to QSFP28 with built-in I/O O/E conversion
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm
• Length: 25 metres
• Data rate: 100 Gbps (100GBASE-SR4 compatible)
• Sheath: LSZH (low smoke zero halogen), flame resistant
• Compliance: manufactured in accordance with MSA, SFF and IEEE specifications; tested to common industry standards

How to use

Connect each QSFP28 plug into the QSFP28 port of the corresponding devices, ensuring the orientation follows the connector keying. The cable is hot-pluggable and requires no additional transceivers in the host hardware because the electrical-to-optical and optical-to-electrical conversion is integrated in the connector modules. Route the cable following standard cable management practices, avoiding sharp bends and excessive tensile stress to preserve the fibre integrity and the smaller bend radius.

Recommendations

Use this 25m OM3 AOC for short-reach 100G links inside racks or between adjacent racks. Maintain bend radius guidelines, keep the LSZH jacket intact, and verify QSFP28 port compatibility on both ends prior to installation. For critical installations, perform link validation and throughput testing after mounting.
