What frequency and tx power of singlemode? You do not need to attenuate 1GbE 1310nm LX (5-10km reach) or 10GbE 1310nm LX optics for very short distances. Tons of ISPs use all 1310/LX optics for intra-rack and intra-suite fiber XCs because they're cheap, easy and multimode is dumb.
If you are using optics which are marketed as capable of 20, 40 or more km reach (and/or 1490nm, 1550nm optics) you do need to attenuate on the Rx.
