Keysight Technologies N4891A 400GBASE FEC-Aware Receiver Test Solution

Feb. 20, 2020
Keysight says its N4891A 400GBASE FEC-aware receiver test solution provides the industry’s first forward error correction (FEC) aware compliance testing system for measurement of frame loss ratio in 400G Ethernet links using FEC.

Keysight says its N4891A 400GBASE FEC-aware receiver test solution provides the industry’s first forward error correction (FEC) aware compliance testing system for measurement of frame loss ratio in 400G Ethernet links using FEC. It supplies one stressed lane and maintains the proper FEC striped test pattern data, without placing stress on the other lanes.

Judge’s comment: “This is a groundbreaking test platform. Historically, systems which have been able to provide stressed analog characteristics have not contained significant digital content to allow for flexible traffic. This test system arrives at a good time in the industry as more FEC and complex digital markers are being deployed in high-bit-rate optical communications.”
