Description

HPE R0M47A 50Gbps SFP56 DAC Cable

Overview

The HPE R0M47A is a 3-meter Direct Attach Copper (DAC) cable designed for high-speed, short-reach network connections. It terminates in two SFP56 connectors, enabling 50Gbps bidirectional data transfer between network devices. This cable is critical for building dense, high-performance network fabrics in data centers or enterprise environments where switch-to-switch or switch-to-server links demand maximum bandwidth with minimal latency and power consumption.

Compatibility

This cable is engineered for use with HPE Aruba networking equipment that supports SFP56 transceivers, including specific models within the Aruba CX 6300, CX 6400, and CX 8300 series switches. It is suitable for direct connections between ports equipped with SFP56 interfaces on these Aruba switches, facilitating high-speed uplinks or inter-switch links.

Installation Notes

Ensure the SFP56 ports on both connected devices are clean and free of debris before inserting the cable. The cable should be seated firmly until the retention clips engage. Avoid sharp bends or kinks, as this can degrade signal integrity. The maximum supported length of 3 meters is ideal for rack-to-rack or intra-rack connectivity.
