Description

HPE R0M46A 50GbE SFP56 DAC Cable

Overview

The HPE R0M46A is a 0.65-meter Direct Attach Copper (DAC) cable designed for high-density, high-performance network connections. It terminates with SFP56 connectors on both ends, enabling 50 Gigabit Ethernet (50GbE) links between network devices. This cable is ideal for short-reach interconnects within racks or between adjacent racks in data centers, enterprise networks, and high-performance computing environments where maximum bandwidth is critical.

Compatibility

This 50GbE DAC cable is compatible with any HPE Aruba networking equipment, and other vendors' switches, servers, or network interface cards that support SFP56 transceivers and 50GbE connectivity. It is designed to work with HPE Aruba's CX series switches and other platforms requiring high-speed, low-latency interconnects.

Installation Notes

Ensure the SFP56 ports on both devices are clean before inserting the cable. The cable requires no configuration; simply plug and play. The 0.65m length is optimized for direct rack-to-rack or device-to-device connections, minimizing cable clutter and signal degradation. Avoid sharp bends or excessive tension on the cable to maintain signal integrity.
