Brimrose all fiber optic, electronically controllable modulators allow the user to vary the output light amplitude, time duration, and periodicity/frequency. Insertion Loss can be as low as 2 dB, Extinction Ratio can be as high as 70 dB, rise times can be down to 5 nsec, periodicity can be up to several hundred MHz. Applications include switching, pulse picking, fast attenuator, etc. Wavelengths can range from near UV to near IR.
A specialized application of modulators is the Programmable Attenuator. Attenuators are a key element in the design of fiber optic transmission systems. Attenuators are used to match the optical power level to the dynamic range of receivers, adjust the input and output levels in EDFAs, equalize the power between different DWDM channels and test the general performance of systems under varying optical power conditions.
