When i connect two cables using a uu coupler, no light passes through the second cable. do you need ud to join two cables as an extension?

The need for UU vs UD depends on the cables themselves. However, you also need to be joining a male end to a female end with these couplers. If both of your MPO ends are female, then you're missing the alignment pins present on the male connector. These pins are essential to getting light through the second cable.
