FC SC ST LC Adjustable Attenuator Mechanical Range 0-40/60dB
Product summary:
Optical attenuator is a very important fiber optical passive
device, which can attenuate the optical signal energy according to
the user's requirements, and is often used to absorb or reflect the
optical power margin, evaluate the loss of the system and various
tests. At present, serialized optical attenuators have been widely used in
the field of optical communication, which brings convenience to
users.
An optical device inserted into an optical path that attenuates the
optical signal power according to a set requirement. It is used to adjust the power of the optical signal transmitted by
the optical communication system or the test system, so that the
system can achieve a good working state. It is also commonly used to detect the sensitivity and dynamic
range of optical receivers.
Optical attenuators can be divided into fixed attenuators,
step-adjustable attenuators, continuously adjustable attenuators,
continuous and step-combined attenuators, etc. Its main performance parameters are attenuation and precision.
Features:
The optical attenuation and optical power output can be set quickly
and accurately, and the optical power control stability time is
less than 100 ms.
Multi-channel attenuator is set at the same time, and multiple
ports are measured simultaneously, which saves a lot of measurement
time;
Built-in high-precision optical power meter ensures the stability
and accuracy of power monitoring;
Simple operation, intuitive graphical user interface, multi-channel
data preview, test status at a glance;
Small size, compact structure. Multiple devices can be customized to expand the number of
channels.
