The QSFP-DD ZR Plus variant complies with OpenZR+ MSA, allowing to cope for distances going from regional to long haul with multiple amplification sites between the end point. This variant is also providing multiple configuration options in terms of Modulation scheme, TX filter shaping, and baud rates on top of what OpenZR+ MSA defines.
This variant is also the one capable of reaching the longest transmission distance thanks to the high-performing O-FEC algorithm.
It is able to support an ~60G baud rate, QPSK, and 8-QAM and 16-QAM modulation scheme to cope with a 200G (QPSK), 300G (8-QAM), and 400G (16-QAM) per wavelength transmission capacity.
It is also capable of supporting 100G signals leveraging QPSK modulation scheme at -30G baud as well as 200G signal at 16-QAM (-30Gbaud) and 8-QAM (-40 Gbaud).
