Powerful 800G and 1.6T testing
EXFO’s BA-4000-L2 is a combined layer 1 BER tester and Ethernet (L2) traffic analyzer for 800G DR4/FR4/LR4 and 1.6T optical engines. It addresses the comprehensive testing requirements of 1.6T optical engines (100G electrical, 200G optical per lane), 800G transceivers (200G per lane), as well as DCO transceivers. The solution includes FEC testing (including FEC statistics), burst error detection and BER calculated from host to end for the industry’s most reliable measure of error when testing optical transceivers, including LPO devices.
