Network Tester
NTA4100
400G Network Tester
Semight Instruments NTA4100 is specifically designed for high speed ethernet traffic test, which supports not just 400GE, but also other speeds as 200GE and 100GE. It can be used to handle comprehensive KP4 forward error correction (FEC) testing and statistics, FEC symbol error injection testing, L1 BERT and the L2 performance testing.
