1.If dBm levels are lower than specification requirements (too much power), add attenuation until correct readings apply. Attenuation should be added in –5, –10, or –25 dBm increments.

2.If dBm levels are higher than specification requirements (not enough power), clean all optics and reduce number of fiber splices/connections. Verify the integrity of the fiber cable, and make sure there are no kinks, breaks, tight coils, or bends.
