The Network Master Pro MT1040A is a portable tester for 400G Ethernet networks utilized in hyper and Colocation data centers.
However, 400G Ethernet Core and Metro networks are evolving to meet the demands of mobile edge and cloud computing deployments as 5G and IoT applications become more widespread. The MT1040A eases the burden of 400G Ethernet testing for all these applications.
Monitoring FEC to ensure signal quality
FEC is an essential 400G technology that applies error correction to the the packet itself and is used to achieve high-reliability integrity of the 400g interface. However, FEC is only able to compensate for signalling errors up to a specific rate. If there are too many FEC corrections, the network performance will degrade.
Consequently, the FEC frequency should be confirmed not only at the same time as the latency and throughput measurements during network installation but also during normal operation. The MT1040A features built-in FEC measurements to highlight corrected signalling errors regardless of the BER, highlighting potential failure points in the network.
