Multi-Channel Multi-Mode Optical Attenuator Attenuation Range 0~40
DB
U8320 Desktop Variable Optical Attenuator offers superior
performance for channel balancing, power equalization, gain tilt
and power adjustment of DWDM systems, EDFA, Interleaver, WSS, OPM,
DPSK, AWG & PLC components, optical amplifiers, and other
general purpose fiber optic test and measurement applications.
The advantages of U8320 desktop optical attenuator are high
measurement accuracy, good stability, easy operation and
maintenance. It usually uses a highly stable light source and a
high-precision photoelectric converter to achieve fast and accurate
measurements. In addition, benchtop optical attenuators are
available in a variety of interface types and specifications to
meet the needs of different fiber optic networks.
When using a desktop optical attenuator, the following points need
to be noted:
Ensure that the optical fiber to be tested is clean and dry, free
of impurities such as dust and oil.
When connecting and measuring optical fibers, be careful to avoid
optical fiber breakage or damage caused by excessive force.
During the measurement process, the stability and cleanliness of
the optical attenuator should be maintained to avoid external
interference;
In the process of use, pay attention to follow the operating
procedures to avoid damage to the optical attenuator and the
optical fiber to be measured.
