472109A Nokia Nokia Optical Transport System Module

The Nokia 472109A is an Element Switch Management Board (ESMB) designed for use within Nokia’s optical transport and network infrastructure platforms. This board provides essential management and switching functions, enabling centralised control of network elements and facilitating communication between system components.

The ESMB is typically deployed within Nokia’s optical networking equipment, supporting carrier-grade telecommunications networks. It plays a critical role in managing data paths and ensuring reliable operation of high-capacity transmission systems used by service providers and large enterprise networks.

This is a legacy Nokia component from earlier generations of optical transport equipment. Whilst these systems remain in active service across many networks, the hardware is no longer in current production, making quality refurbished units a practical solution for maintenance and spares provisioning.
