Optical Fiber Attenuator Precision Polishing Inline Fully
Compatible With SC APC Connect 2.0mm Blue Cable
Optical attenuator is a passive device used to reduce the power
level of an optical signal. It is generally used in single-mode
long-haul applications to prevent optical overload at the receiver.
Optical attenuator is widely used in CWDM&DWDM, CATV systems,
data center networks, test equipment and other high power
applications.
CVOA comprises 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.
Collimator variable optical attenuator is an useful tool for the
optical components and systems test.

Application
Variable in-line optical attenuators comprises 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.
