BlueOptics X5DH4-BO InfiniBand fibre optic cable 20 m SFP28

The BlueOptics X5DH4-BO InfiniBand fibre optic cable 20 m SFP28 is a 20-metre active optical cable (AOC) with SFP28 connectors on both ends designed for high-speed short-range optical links. It supports 25GBASE-SR4-class multimode operation and implements SFP28-to-SFP28 connectivity according to MSA standards, providing a pre-assembled fibre solution for data centre and high-performance computing environments that require low latency and high bandwidth over a 20 metre span.

Advantages

This AOC offers plug-and-play SFP28 connectivity without the need for separate transceivers or patching, reducing installation time and signal loss associated with connectorized fibre. Built to MSA specifications and intended as compatible with systems that support the referenced 25GBASE-SR4 AOC, it combines multimode optical transmission with active transceivers at each end to maintain signal integrity and support high-speed Ethernet and similar protocols. The pre-assembled design reduces susceptibility to electromagnetic interference and eliminates manual fibre polishing or cleaning steps associated with field-terminated links.

How to use

Install the BlueOptics X5DH4-BO by inserting each SFP28 connector into compatible SFP28 ports on your network devices, ensuring the host devices officially support SFP28 AOCs of this class. Handle the cable by its connector housings and avoid sharp bends along the fibre path; route the cable through standard data centre cable management to maintain minimum bend radius. If your equipment supports Digital Diagnostics Monitoring, enable or query DDM/DOM parameters through the host system to monitor supply voltage, laser bias, output/received power and module temperature in real time.

Recommendations

Confirm device compatibility with SFP28 AOC modules and check that the host firmware or software permits operation of third-party AOCs if DDM/DOM access is required. Maintain clean port interfaces, secure the cable to prevent strain on connectors, and follow recommended bend-radius and routing practices in racks and enclosures to ensure optimal performance and long service life.
