Article says "The performance of the system is expected at 292 kbit/s at a distance of 0.4 AU" but this is slower than the RF comms from MRO mentioned. ? - Rod57 (talk) 11:07, 20 October 2019 (UTC)Reply

Unlike radio communications, the current state of the art for optical communications is not Heterodyne. That makes a huge difference when it comes to signal to noise. Radio communications has had over a century to mature. When it comes to optical com, I'm afraid we're still at the stage of Marconi and Tesla. Fcrary (talk) 22:12, 20 October 2019 (UTC)Reply

I checked the ref. The 292 kbps is just for the uplink so I've amended the article. The Poster ref has a graph of the downlink bandwidth for different distances and receivers. Shows 10x MRO radio bandwidth. Need to tabulate in article. - Rod57 (talk) 22:20, 28 July 2020 (UTC)Reply
