Attenuator 8-Channel Multi-Mode Optical Attenuator Range0~35dB
(40dB Type)
The 8-channel multi-mode optically controlled optical attenuator is
an optical device with multiple channels, which can adjust the
attenuation of optical signal through optical control, and is
widely used in optical communication, optical testing, optical
fiber sensing and other fields.
Product characteristics
Multi-channel design: With 8 independent channels, multiple optical
signals can be processed at the same time, improving the efficiency
of tests or applications.
Optical control adjustment: attenuation adjustment of optical
signal is realized through optical control, which has the
characteristics of fast response speed and high adjustment
accuracy.
Multi-mode support: Support multi-mode fiber, suitable for a
variety of fiber transmission systems.
High accuracy: Attenuation accuracy is usually high, which can meet
the needs of precision optical tests or applications.
Good stability: The stability time of the optical power control is
short, which can ensure the stability of the optical signal during
transmission.
