I wanted to ask whether this is the system you had formerly asked for suggestions for performance improvement. I once used DCF and once reduced the WDM laser linewidth to 0.1 MHz, which is acceptable for low power CW lasers, but neither of these methods made a remarkable change in the Q-factor. However, I suggest that you go with laser linewidth reduction and see if that helps.
