LM1000SFPS4 : 4-Port Gigabit Ethernet Fiber Load Module (Does not include SFP transceivers), CPU per port; Full features -- supports routing protocols, Linux SDK, and L4-L7 Applications

Ixia's TXS family of Ethernet Load Modules is the first to offer wire-speed Layer 2-3 traffic generation and analysis with high-performance, scalable routing protocol emulation, and true Layer 4 through Layer 7 session emulation. The TXS family offers the highest port density solution for autonegotiable 10/100/1000 Mbps Ethernet over copper, as well as Gigabit Ethernet over fiber -- providing up to 240 Gigabit Ethernet test ports on a single chassis.
