We experimentally investigated the performance degradation due to broadband light source (BLS) polarization in wavelength-division multiplexing-passive optical network systems based on a wavelength-locked Fabry-Perot laser diode. The results showed that the BLS polarization difference between two polarization states should be less than 3 dB, and its injection power should be greater than -18 dBm for a received-power penalty of less than 1 dB.
