As the responsibilities of telecom field-installation personnel increase-from testing traditional and lower-rate SONET/SDH networks primarily used to transport telephony and private-line services to higher-speed (40/43 Gbit/s) networks supporting multiservices including packet-based services-the performance requirements of the underlying transport networks become more stringent, making testing and qualification of these transport networks more challenging. This application note outlines the service disruption time (SDT) measurement approach of EXFO’s FTB-8140 Transport Blazer 40/43 Gigabit SONET/SDH Test Module that should be performed during the installation and commissioning of network elements and their new circuits.
