471720A.104 Nokia Nokia Optical Transport System Module

The Nokia 471720A.104 is an FTIB (Fan Tray Interface Board), a system module designed to manage and monitor cooling fan operations within Nokia optical transport and telecommunications equipment. This board provides the critical interface between the system’s fan tray assembly and the main chassis, ensuring proper thermal management and environmental monitoring.

The FTIB is deployed within Nokia’s optical networking platforms, where it plays an essential role in maintaining system reliability by controlling fan speeds, monitoring airflow, and reporting thermal status to the system management plane. Proper cooling is vital for high-density optical transport equipment operating in demanding telecommunications environments.

This module is associated with Nokia’s legacy optical transport portfolio. As telecommunications networks evolve, these interface boards remain necessary for operators maintaining existing Nokia infrastructure or requiring spare components for deployed systems.
