Table 1 The optical spectral efficiency, power penalty, and BER under different scenarios.
From: A PDM-based 128-Gb/s PAM4 fibre-FSO convergent system with OBPFs for polarisation de-multiplexing
Scenario | Proposed PDM | Traditional PDM | Two Parallel Polarised Optical Carriers |
|---|---|---|---|
Metric | |||
Optical Spectral Efficiency | 64 Gb/s/λ | 128 Gb/s/λ | 64 Gb/s/λ |
Power Penalty | 8.8 dB | 9.4 dB | 6.6 dB |
BER | 10−9 | 2.2 × 10−5 | 10−6 |
