With fiber connections, remember there is a transmit strand and a receive strand. The first thing to do besides making sure the interface is no shut and the module is firmly seated, is to try crossing the pairs of your fiber. IE, take the "clip" off the end if necessary, and switch the "A" and "B", so that the one on the left is now on the right, and the one on the right is now on the left. (only on one end of the fiber strand)
My bet is that you have your transmit connecting to their transmit, and their receive to your receive. If you swap the connectors on one side, that may very well do it. If that doesn't work, I'd get a 2nd Xenpak if at all possible and connect them back to back with a "crossover" fiber as shown right above and make sure it links up that way. Could be a bad Xenpak.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
