Spirent SmartBits SMB-6000B Chassis with POS-3500B’S X 2

The Spirent SmartBits SMB-6000B chassis is a high-density network performance analysis system that integrates up to twelve interface modules for rigorous testing and validation of network infrastructure. This configuration pairs the chassis with two POS-3500B modules, enabling OC-3c/STM-1 (155 Mbps) and OC-12c/STM-4 (622 Mbps) Packet over SONET/SDH testing at single-port density per module. The system delivers detailed performance analysis, protocol validation, and troubleshooting across SONET/SDH and IP infrastructures.
