Cavo in fibra ottica InfiniBand BlueOptics MFA1A00-E050-BO 50 m QSFP28

The BlueOptics MFA1A00-E050-BO InfiniBand fibre optic cable 50 m QSFP28 is a 50-metre active optical cable (AOC) with QSFP28 connectors designed for high-speed links in data centres and HPC environments. The cable uses multimode fibre with integrated transmitters and receivers at both ends to support short-reach 100G applications over a 50 m distance. It conforms to QSFP28 electrical and optical interface expectations and is compatible with systems that support the corresponding SR4-style 100G optical interconnects.

Advantages

This AOC provides a factory-terminated, plug-and-play connection that eliminates the need for separate transceivers and patch cords while maintaining the signal integrity required for 100G short-reach links. The QSFP28-to-QSFP28 form factor reduces connector density and simplifies rack-to-rack or switch-to-switch interconnects. Active optical transmission minimizes power loss and crosstalk associated with long copper runs, enabling stable high-bandwidth performance across the full 50 m length.

Suitable for

• Interconnections between switches, routers, and servers in data centres
• High-performance computing clusters requiring 100G InfiniBand links
• Short-reach links for storage arrays and SAN environments
• Rack-to-rack or row-to-row fiber links in enterprise network rooms

Key specifications

• Length: 50 metres
• Connector type: QSFP28 male to QSFP28 male
• Transmission type: Active optical cable (AOC) with integrated Tx/Rx
• Fiber type: Multimode fiber suitable for short-range 100G
• Supported protocols: 100G Ethernet and compatible InfiniBand short-reach modes
• Form factor: QSFP28 optical interconnect for 100G links

How to use

Install the QSFP28 connectors into compatible QSFP28 ports on the devices to be connected, ensuring proper orientation and a secure latch. Verify that the connected equipment supports 100G short-reach optical links and any required interface settings. After insertion, allow devices to negotiate link parameters; monitoring link LEDs or management interfaces will confirm an active 100G connection. Handle the cable by the connector housings and maintain the specified bend radius for multimode fiber to avoid performance degradation.

Recommendations

Store and route the cable in cable trays or appropriate management systems to prevent tight bends or crushing. Use this AOC for short-reach 100G interconnects where direct QSFP28-to-QSFP28 links reduce system complexity; for longer runs or mixed vendor environments, verify compatibility and consider using transceiver-plus-patch-fiber solutions where appropriate.
