The simulation design for the layout shown in the video consists of 3-user fiber bragg grating (FBG) based OCDMA network at 200 Mbit/s. Uniform FBGs are used to impelement the Modified Quadratic Congruence (MQC) codes by spectral amplitude encoding. The signal is generated using an incoherent source modulated with NRZ PRBS data using a Mach-Zehnder Modulator. The optical link is 10 km of single mode fiber. The receiver is comprised of two spectral filters and two photodetectors connected in a balanced configuration which perform the decoding with a low-pass filter and a BER analyzer. In this experiment User 1 and 2 are ON and User 3 is OFF.
I hope this is helpful to you.
