400 Gbps, 1 Tbps Simulation in Optisystem

Hi Ramin,
there is no constraints in the bit rate used so you can use one of the examples that is similar to your and change the nit rate to 400G then check the results if it is similar to what you expect or you need to adapt the medium of transmission to have acceptable BER, SER, ..etc.
Or you may start with B2B system without transmission medium, then add optical fiber.

Hope that helps,
let us know if you have any other concern,
thanks

Dear Hashemi
You can simulate a 400G or 1T system in Optisystem. For example, you can use multiplexing techniques like WDM or use different modulation schemes to achieve such high bit rates.

hello can you help me how to make a link at 400 Gbps with PAM 4 modulation
