SW-1-Line-coding-schemes document for nrz and rz

1. Analysis of RZ and NRZ line codings
Software Experiment – 3
Optical Fiber Communication Lab

2. Aim
• To study the performance analysis of
– NRZ line coding
– RZ line coding
• To observe and note down the line coded output
• Tabulate the Q-factor, BER, for various input wavelengths
• Save the eye diagram for each output obtained

3. NRZ line coding
SMF length = 120 km, dispersion parameter = 16 ps/nm/km
DCF length = 24 km, dispersion parameter = -80 ps/nm/km

4. NRZ and RZ line coding formats

5. NRZ – Sample output
