Spirent 400G Ethernet Test Solution - A Technical Overview


Published on

Spirent offers a complete testing solution for early design and development of 400G Ethernet systems, with a one-slot blade form factor compatible with Spirent’s existing chassis and its other Ethernet products. Testing 400GbE network devices is the fundamental building block to delivering reliable, high performing systems, and starts with validating the link’s ability to pass up to line rate traffic as well as testing the functionality, performance, scalability and QoE of the upper-layer engines that deliver services.
