The Optical Internetworking Forum 400ZR implementation agreement targets cost-effective coherent router-to-router interconnects and amplified links up to 120 km with a 400 GbE payload. 400ZR+ aims to extend this to even longer distances for 100G to 400G traffic.
The M8290A is compact and modular in the AXIe form factor. It incorporates a 92 GSa/s optical modulation analyzer and a 92 GSa/s four-channel electrical digitizer resulting in a flexible test solution to characterize integrated, coherent receivers ICR and coherent transmitters for 400ZR, including assemblies and subassemblies. When combined with an M8196A Arbitrary Waveform Generator, it can perform system-level tests.
