Description
The Fujitsu TCA2-ST31 is a timing/synchronization interface module used in the Fujitsu Flashwave 4500 (also known as FLASH 2400 ADX) optical transport platform. In parts listings, this number is shown as the timing unit integral to the Flashwave 4500 family, responsible for providing synchronization and clock distribution across the transport shelf to ensure proper timing for SONET/SDH and related networks. Flashwave 4500 is a multiservice transport system that supports high-speed optical carriage and multiplexing of SONET/SDH signals.
