The Spirent Smartbits LAN-3311A is a 2-port 1000Base-X Gigabit Ethernet test module engineered for the SMB6000B/C chassis. This TeraMetrics line module delivers wire-rate traffic generation and analysis across dual ports, each rated at 1 Gbps. It supports hot-swappable GBIC converters for flexible fiber connectivity, enabling multi-mode or single-mode fiber deployment. The LAN-3311A executes comprehensive Layer 2 and Layer 3 network testing, from QoS analysis to device qualification under extreme traffic loads.
