Recommended Fiber Transciever?

Does anyone use fiber for going up towers? We want a good one on a problem tower we have. We’re replacing everything on the tower (CMM, APs, cables) the only thing left to replace is the transceiver and we want to make sure we get a nice one that isn’t too expensive.
Any recommendations?

If these are as solid as the VDSL modems we use they will be great
