4B3T Decoding

[KSVParticipant]

Hello all,
im trying to send a 4b3t sequence to a fiber and decode at the receiver side. But im not getting any signal after M-ary threshold detector. I’ve attached the optisystem file.

Make sure that the bit rate in the M-ary detector reflects the actual bit rate and the the threshold amplitudes need to match the signal as well.

Hi,
I am unable to get the BER for 4B3T. But I am able to get the eye diagram.

Hi,

I’m getting a BER of 0 now. The problem was that you were comparing the original bit sequence to the ternary signal before being decoded.

I used a BER Test Set instead as well.

Hi Damian,
im getting an error when I open the file saying “calculate…has a bad format” and :failed to load document from page”. Please help me

Your version might be older than mine. I am using 13.0.2

Hi
Reinstalling optisystem fixed the errors. Thank you
