Plug In Attenuator
An optical attenuator is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. NWC attenuators utilize optimized doped fibers to reduce the power level of an optical signal.
This method show higher performance than fiber splices or fiber offsets. NWC attenuators are capable of performing in the 1310, C and L Bands and also have capablility of withstanding over 1W of high power light exposure for extended periods of time. Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution makes them ideal for DWDM.
