$LWLG Great webcast, favors LWLG technology over & over!
800G technology: Does double capacity mean twice the performance?
https://gateway.on24.com/wcc/gateway/Infoneti...d=80032820
at about 10 mins, new technology for 400Gb and beyond capable is needed - its one thing to increase the data rate using spectral efficiency, but spectral efficiency is difficult to scale especially in longer Reach applications, Metro and Long Haul, you really need to move to use higher Baud rates, if you move 2x up in spectral efficiency your Reach goes down by a factor of 4, if you do that with Baud rate your Reach only goes down by about 10%
at about 18 mins Ciena guy Kent talks about all the considerations needed when choosing what Baud rate is "ideal" for getting to 800Gbs, there are multiple factors being considered, but the answer they conclude is 95 GBaud!
This whole presentation has the need for LWLG technology written all over it!
Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the media access control (the channel access protocol).[1]
