The Spirent Smartbits LAN-3201A is a single-port Gigabit Ethernet module that delivers full wire-rate traffic generation and analysis for network device testing and qualification. Built to IEEE 802.3z standards, this SFP-based module integrates directly into SMB6000B and SMB6000C chassis systems to evaluate Layer 2 and Layer 3 performance under controlled or extreme load conditions. It supports simulation of up to 8,192 end devices and streams, with capacity for 512 million simultaneous flows, making it ideal for comprehensive interoperability and RFC 2544 compliance testing of routers and network equipment.
