Keysight Technologies announced two new solutions - the N4891A 400GBASE Forward Error Correction (FEC)-aware compliance test solution, which finds performance and interoperability issues early in the design and validation process of data center-related devices, and the A400GE-QDD 400GE multiport test system, which characterizes and quantifies the actual bit error rate (BER) and forward error correction (FEC) performance of silicon communication devices.
