How to write code for perform TWDM PON and calculate Delay, Throughput, Jitter? Please can you give me sample code?

Hey,

I understand that you want to perform Time and Wavelength Division Multiplexing Passive Optical Network (TWDM-PON) and calculate parameters like delay, throughput and jitter.

Here is some sample code that achieves the same.

% Define the Parameters
num_wavelengths = 4;
num_time_slots = 10;
time_slot_duration = 1e-3; % in seconds
bandwidth_per_wavelength = 10e9; % in bits per second

% Simulation
data_transmitted = zeros(num_wavelengths, num_time_slots);
for w = 1:num_wavelengths
    for t = 1:num_time_slots
        % TDM: Divides the communication channel into time slots
        % WDM: Transmits multiple signals on different wavelengths
        data_transmitted(w, t) = bandwidth_per_wavelength * time_slot_duration * rand();
    end
end

% Delay: The time it takes for data to travel from the source to the destination
total_data = sum(data_transmitted, 'all');
delay = total_data / (num_wavelengths * bandwidth_per_wavelength);
fprintf('Delay: %.2f ms\n', delay * 1e3);

Delay: 5.73 ms

% Throughput: The rate at which data is successfully transmitted over the network
throughput = total_data / (num_time_slots * time_slot_duration);
fprintf('Throughput: %.2f Gbps\n', throughput / 1e9);

Throughput: 22.92 Gbps

% Jitter: The variation in packet delay at the receiver
packet_delays = sum(data_transmitted, 2) / bandwidth_per_wavelength;
jitter = std(packet_delays);
fprintf('Jitter: %.2f ms\n', jitter * 1e3);

Jitter: 0.17 ms

I hope this helps.
