Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-50M-MV-BO 50m QSFP28

The BlueOptics Q28-AOC-50M-MV-BO InfiniBand fibre optic cable 50m QSFP28 is a 50-metre active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for 100G data links. Built to MSA QSFP28 specifications, this aqua-coloured multimode AOC integrates transmitters and receivers at both ends to support high-speed 100GBASE-SR4 applications across data centres, high-performance computing clusters and network aggregation layers. The cable reduces the need for patching and cleaning associated with separate transceivers and patch cords while providing immunity to electromagnetic interference typical of optical links.

Advantages

The AOC offers plug-and-play installation with pre-terminated QSFP28 connectors and supports bi-directional optical transmission at up to 100 Gbit/s over a 50 m multimode link. Compliance with MSA QSFP28 mechanical and electrical specifications ensures interoperability with compatible hardware. Integrated digital diagnostics (DDM/DOM) provide live monitoring of supply voltage, laser bias, optical transmit and receive power and temperature to simplify maintenance and troubleshooting. Construction using industry-grade optical lasers and ICs aims to deliver long service life and stable performance in demanding environments.

Suitable for

• Data centre switch-to-switch or switch-to-server interconnects
• High-performance computing (HPC) clusters and InfiniBand environments
• Storage area network and storage system interconnects
• Top-of-rack and aggregation layer connections within 50 m

Key specifications

• Connector type: QSFP28 to QSFP28 (MSA compliant)
• Data rate: up to 100 Gbit/s (100GBASE-SR4 compatible)
• Length: 50 metres (pre-assembled active optical cable)
• Fiber type: multimode optical fiber suitable for SR4 transmission
• Integrated features: transmitters and receivers at both ends, Digital Diagnostics Monitoring (DDM/DOM)
• Color: aqua (for easy identification in fibre installations)

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port of the devices to be connected, ensuring the latch engages. No additional transceivers or field termination are required. Confirm that the host devices support QSFP28 AOC modules and, if needed, enable or verify DDM/DOM support in the system management interface to access diagnostic readings. Avoid sharp bends and maintain recommended bend radius for multimode fibre during routing and rack installation to preserve signal integrity.

Recommendations

For reliable operation, route the cable with gentle bends, avoid torsion and secure it to prevent strain on the QSFP28 connectors. Verify that connected equipment supports 100GBASE-SR4 over AOC to ensure compatibility and enable digital diagnostics in the host system for real-time monitoring of optical parameters.
