Agilent/Keysight A400GE-QDD

The Keysight A400GE-QDD is a compact, high-performance test system designed for validating the Bit Error Rate (BER) and Forward Error Correction (FEC) performance of 400 Gigabit Ethernet (400GE) electronics. This system is instrumental for engineers and labs involved in testing chips, optical transceivers, and port electronics, providing a dedicated solution for qualifying BER on 400GE interfaces. It offers a system-level view of BER and FEC performance across all lanes in real-time, enabling rapid issue identification.
