BLS polarization-induced performance degradation in WDM–PON systems based on wavelength-locked FP-LDs

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 po...

Description
Summary: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.
