I've bought some 25GB 40km bidi sfp and my fiber length is about 15km. I have a 5db attenuator on each end and my switch now reports about 15.5db on the receive side.The previous 100gb qsfp28s I was using on the same fibers was getting 6-7db. Should I remove one of the attenuators? - FS.com México

Yes, you can remove one of the attenuators. It is recommended that the receiver power be controlled between -5dBm ~-15dBm. Por B***n en 23 de dic. de 2021
