ROF1375247/2 Ericsson Ericsson AXE System Module

The Ericsson ROF1375247/2 is a PFU2 (Power Filter Unit 2), a power conditioning and filtering module designed for use within Ericsson’s telecommunications infrastructure. This unit provides essential power filtering functions to ensure clean, stable power delivery to sensitive exchange equipment, protecting against electrical noise and voltage fluctuations.

The PFU2 is designed for deployment within Ericsson AXE digital switching systems and related telecommunications platforms. These power filter units are critical components in maintaining system reliability and protecting digital circuitry from power-related disturbances in central office and exchange environments.

This is a legacy component from Ericsson’s established AXE platform, which has been widely deployed globally in fixed-line telecommunications networks. While the AXE system is now considered mature technology, many installations remain in active service, creating ongoing demand for replacement and spare components.
