HPE R0M45A - 25 Gb/s SFP28-to-SFP28 Active Optical Cable (7 m)
Overview
The HPE R0M45A is a factory-specified active optical cable (AOC) linking two SFP28 ports at 25 Gb/s data rate, with a cable length of approximately seven metres. Its purpose is to provide a high-density, low-power, low-latency interconnect between switches, servers or other networking gear with SFP28 slots where multi-mode optical or active cable infrastructure is preferred over passive copper or separate transceiver + fibre patch. According to the vendor documentation this cable is supported by HPE/Aruba switch series that accept SFP28 25G active optical cables.For a network engineer, this means when you need to connect two 25 Gbps SFP28 ports over a short run (within rack or between adjacent racks) and you want the simplicity of a pre-terminated active cable, the R0M45A is a strong choice.
Key Features
Supports 25 Gb/s data rate over SFP28 interface (per specification guide).
Cable length: 7 metres (≈ 22.9 feet)×useful for mid-rack or rack-to-rack short-reach runs.
SFP28 form-factor at each end: plugs directly into SFP28 ports×no separate transceiver + fibre patch required
Recognised by HPE/Aruba as a supported cable in their SFP28 port product lines.
