Product Details
Ultra-Low Loss Manual Variable Optical Attenuator Single Mode
Variable in-line optical attenuators comprise a dual fiber
collimator and a reflection component separated by a linear
moveable ND filter. They are used to permit dynamic control of
optical power levels in a fiber and can be applied to adjust power
level of signal in the optical communication at the output of light
sources, E/O converters and for the linear or dynamic range of
power meter.
