BlueOptics 100G-QSFP-QSFP-AOC-5M-BO cabo de fibra ótica InfiniBand 5m QSFP28 macho/macho

The BlueOptics 100G-QSFP-QSFP-AOC-5M-BO is a 5-metre active optical cable (AOC) with QSFP28 male connectors on both ends, designed for high-speed InfiniBand and 100G Ethernet links. It supports 100GBASE-SR4-compatible transmission over multimode fibre and integrates transmitter and receiver electronics in the cable assembly to simplify installation and ensure correct signal interfacing with QSFP28 ports. The pre-assembled AOC reduces the need for patching or cleaning of connectors and is suitable for short-reach interconnects within racks and between adjacent equipment in data centre and high-performance computing environments.

Advantages

This AOC provides a fixed 5 m high-bandwidth link with simultaneous transmit and receive channels via QSFP28 connectors, eliminating the variability of separate transceivers and patch cords. Built to MSA QSFP28 standards, the cable assembly offers plug-and-play interoperability with equipment that supports QSFP28 AOCs. The integrated Digital Diagnostics Monitoring (DDM/DOM) function supplies real-time information such as supply voltage, laser bias current, output and received optical power, and temperature to assist in remote diagnostics. Using high-quality optical and electronic components, the BlueOptics AOC is intended for reliable operation with low latency and long service life.

Suitable for

• Short-reach 100G connectivity between switches and routers within a rack or across adjacent racks
• Interconnects between servers and top-of-rack switches in HPC and data centre environments
• High-performance InfiniBand links and Ethernet 100GBASE-SR4 applications

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active Optical Cable (AOC) with multimode fibre and integrated transceivers
• Length: 5 metres
• Data rate: up to 100 Gbit/s (100GBASE-SR4 compatible)
• Digital Diagnostics: DDM/DOM (MSA SFF-8472 compliant) for real-time monitoring
• Compliance: QSFP28 AOC MSA mechanical and electrical specifications
• Suitable transmission medium: multimode fibre for short-reach links

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the latch engages securely. No additional transceivers or patch cords are required; the cable assembly contains the optical transceivers and active electronics. Verify that connected hardware supports QSFP28 AOCs and, if needed, enable or check DDM/DOM monitoring in the host equipment to access diagnostic values. Avoid sharp bends and excessive tension when routing the cable to maintain optical performance.

Recommendations

For optimal results, route the AOC with a bend radius that meets manufacturer guidelines for fibre assemblies, keep the cable away from electromagnetic noise sources (although optical links are immune to EMI), and confirm firmware or driver compatibility on networking equipment when installing third-party AOCs. Use the DDM/DOM readings to monitor link health and plan preventive maintenance.
