At this point, with 400g coherent in production never mind long-haul testing; why bother lighting with anything slower than 100g coherent, especially at essentially the same price. It just makes no sense. It got skipped. We’re better for it IMO.

To be fair, I did say that to begin with. ;) Outside of the US, in our quaint little European countries, passive muxing with direct detect does often make more sense financially Those coherent hardware providers have some eye-watering price lists, and only begin to make sense on spans >100km. Or if you actually need 400G transport to make use of N*100G services. -- Tom
