## Summary description

The BlueOptics MFA1A00-E005-BO is a 5 m InfiniBand fibre optic cable featuring QSFP28 connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and high-performance computing environments. The male-to-male configuration makes it suitable for direct connections between devices, providing optimal performance and minimal signal loss.

## Long description

The BlueOptics MFA1A00-E005-BO InfiniBand fibre optic cable 5 m QSFP28 Male/Male is a 5-metre active optical cable (AOC) with QSFP28 connectors on both ends, designed for high-speed InfiniBand and 100GBASE-SR4 applications. It provides a pre-assembled multimode fibre link with integrated transmitter and receiver electronics in each QSFP28 module, enabling direct device-to-device connections in data centres, high-performance computing clusters and network racks where QSFP28-to-QSFP28 interfaces are used.
Advantages
The cable supports high-bandwidth transmission and low-latency links through optical transmission, which is inherently immune to electromagnetic interference. As an active optical cable with QSFP28 modules, it eliminates the need for patching or field termination and reduces attenuation concerns typical for patch cord assemblies. The integrated digital diagnostics (DDM/DOM) capability facilitates remote monitoring of optical parameters where supported by host hardware. The 5 m length provides a practical balance between reach and cable management within racks and short inter-rack connections.
Suitable for
Direct connections between QSFP28 ports on switches and routers
Interconnects in high-performance computing (HPC) clusters and InfiniBand fabrics
High-speed storage and server interconnects supporting 100G applications
Short-distance data centre links and rack-to-rack cabling up to 5 m
Key specifications
Connector type: QSFP28 male to QSFP28 male
Cable type: Active optical cable (AOC) with multimode fibre
Nominal length: 5 metres
Supported protocol speeds: up to 100 Gbps per cable (100GBASE-SR4 / InfiniBand-compatible)
Integrated features: transmitter and receiver modules in each connector; digital diagnostics monitoring (DDM/DOM) support
How to use
Install by inserting the QSFP28 connectors into compatible QSFP28 ports on the devices to be connected, ensuring proper alignment and latch engagement. Confirm that the host devices support QSFP28 AOC modules and, if you require DDM/DOM data, that the hardware and management software expose those diagnostics. No field termination or fibre polishing is required; the pre-assembled cable is ready for immediate use. For initial setup, verify link status and negotiated speed on both endpoints after insertion.
Usage recommendations
Avoid tight bends and excessive mechanical stress on the cable; maintain the manufacturer’s minimum bend radius during routing. Use in equipment and environments that officially support QSFP28 AOC modules to ensure compatibility and access to diagnostic functions. For long-term reliability, route and secure the cable to prevent repeated flexing and inspect connectors for contamination before insertion.
