Cavo in fibra ottica InfiniBand HPE R0M47A 3 m SFP56 nero

The HPE R0M47A 3 m InfiniBand/fibre optic cable with SFP56 connectors is designed for high-speed data transmission in professional networking environments. This 3‑meter black cable connects SFP56-capable ports on switches, servers and storage devices, providing low-latency, high-bandwidth links suitable for demanding data-center and enterprise applications. The cable's construction emphasizes signal integrity and durability to support sustained operation under standard rack and data-center conditions.

Advantages

This InfiniBand/fibre optic cable supports SFP56 interfaces at both ends, enabling reliable 25 Gb/s (per lane) and compatible high-speed connections with minimal signal loss. The 3 m length offers a practical reach for rack-to-rack or within-rack connections without excess slack. The cable's robust jacket and connector housings are built to withstand repeated insertion and routing in confined spaces, while maintaining consistent optical performance for latency-sensitive workloads.

Suitable for

• Interconnects between SFP56 ports on switches, NICs and storage arrays
• High-performance computing and InfiniBand deployments requiring low latency
• Data-center top-of-rack and middle-of-row cabling where a 3 m reach is required
• Enterprise server-to-switch links and cluster interconnects

Key specifications

• Connector type: SFP56 on both ends
• Length: 3 meters
• Cable color: Black
• Media: Fibre optic suitable for high-speed serial links
• Typical application: InfiniBand / high-bandwidth server and storage interconnects

How to use

Verify that both devices support SFP56 transceivers and that the ports are compatible with passive or active optical cables as required. Route the cable along rack pathways to avoid sharp bends and secure it with cable management to prevent strain on the connectors. Insert each SFP56 connector into the device port until it clicks, and confirm link status through device LEDs or management interfaces. For best performance, avoid kinking the fibre and maintain bend radii recommended by the equipment manufacturer.

Recommendations

Store and handle the cable in a clean, dry environment; avoid exposing fibre end faces to dust or debris. When installing in dense cabling environments, label both ends to simplify maintenance and ensure the cable length matches route requirements to minimize excess slack.
