The problem is not in the laser diodes themselves, because they are very reliable. Please check the laser drivers. Open the left cover and turn off the power supply of the lasers. Then open the cover downside and find the laser drivers. Please change the positions of laser driver N7 with the last N23. Please mind that they are one and the same pcb and the numbering starts from 0 to 23. Use ground strip!!!

Hi Skymaster,
You read the Techplanet very accurately But try to think... Then you will see that DDB is not the problem
Good luck!
