OSA 5548C SSU
Synchronization Supply Unit 
 
Product Overview Our OSA 5548C Synchronization Supply Unit is a scalable synchronization solution ranging from 20 unprotected outputs up to 1,000 protected outputs by adding up to four expansion shelves to the core unit. Its ultra-compact footprint makes it ideal for telecom operators to provide scalable network synchronization in over-crowded ex- changes. The distributed intelligence message passing system of our OSA 5548C SSU eliminates single points of failure and guarantees reliable uptime. Core unit and expansion shelves share the same modules, minimizing overall administrative complexity and enabling reduced homologation activity.
