Even when splicing identical fibers together, if they are not perfectly aligned, optical power will be lost and attenuation across the splice will exist. Likewise, mismatches between fiber geometry and intrinsic fiber parameters (e., numerical aperture) can result in the loss of optical pulse. The impact of hydrogen (Hâ‚‚) on standard single-mode optical fibers represents a significant issue in optical telecommunication systems. An efficient optical data link must have enough light. Optical power loss (attenuation) refers to the reduction of signal strength as light propagates through fiber. Measured in decibels (dB), loss degrades signal quality, limits distance, increases bit-error rate, and escalates infrastructure cost. Losses can be introduced by various means such as intrinsic material absorption, scattering, bending, connector loss and more.
