Spirent LAN3310A

The Spirent LAN3310A is a 2-port Gigabit Ethernet SmartMetrics module for testing network device performance and interoperability. It functions as a network impairment emulator, introducing controlled conditions to simulate real-world scenarios during validation. The module integrates with Spirent SmartBits chassis (SMB-6000B and SMB-600) to expand testing capabilities across enterprise and service provider networks.
