Attenuators can be made by introducing an end gap between two fibers (gap loss), angular or lateral misalignment, poor fusion splicing (deliberately), inserting a neutral density filter or even stressing the fiber (usually by a serpentine holder or a mandrel wrap). Optical attenuators are passive components used to reduce optical signal power to a controlled level within a fiber optic system. FC/PC or LC/APC). Receiver Operating Range: -15 to -30 dBm (That means at power levels above -15 dBm, the receiver will overload and below -30 dBm the signal to noise (S/N) ration will be low and cause a high bit-error-rate. ) The Power Budget is calculated from the transmitter output - (0 dBm) - to the minimum power. FS fixed and variable fiber optic attenuators with leading attenuating fibers guarantee consistent and stable fiber attenuation (0~60dB) in WDM transmission. Our male-to-female buildout optical attenuation (Pads) are available. Lateral or axial misalignment occurs when the axes of two fibers are separated by distance 'd'.
