Huub,
I just find some information in G.Sup39 (02/2016).
Best regards,
Michel
I remark there is no specific recommendations about line coding for OTN.Did you look at G.959.1 and G.698.2?
It seems that QAM is only used in DWDM.
Have you, please, an advice for this subject ?
Did you look at G.959.1 and G.698.2?
OTN on the optical fiber uses the same modulation as DWDM.
The difference between OTN and DWDM is visible at the digital
content (bits and bytes).
I hope it is clear now.
Did you look at G.959.1 and G.698.2?
Perhaps, I read these recommandations too quickly. Thank you for your recall.
G.959.1 notes NRZ, RZ, and PAM4 (for 50 Gbit/s), but not QAM.
G.698.3 notes NRZ, and DP-DQPSK (for 100 Gbit/s), but not QAM
OTN on the optical fiber uses the same modulation as DWDM.
The difference between OTN and DWDM is visible at the digital
content (bits and bytes).
I keep in mind this statement.
There is not yet indication of 16-QAM for OTN (amplitude modulation
together with phase modulation).
There is only amplitude modulation, or only phase modulation.
I hope it is clear now.
It begins !
...I was looking at contributions proposing to add
the DP-16QAM...
