The 8-Channel Multimode Optically Controlled Optical Attenuator
850nm
The 8-channel multi-mode optical attenuator is widely used in the
field of optical communication. It has the characteristics of
multi-channel design, precise control of optical signal and high
reliability.
The 8-channel multi-mode optically controlled optical attenuator
integrates eight independent optical attenuator channels, each of
which supports multi-mode fiber and is capable of handling
simultaneous attenuation of multiple optical signals. This design
not only improves the test efficiency, but also reduces the
equipment cost, and meets the test requirements of complex optical
fiber communication system.
Product characteristics
Multi-channel and multi-mode support: The device provides eight
channels, each channel supports multi-mode fiber, which can
simultaneously handle the attenuation of multiple optical signals,
improving the test efficiency.
Precise control: Precision stepper motor or MEMS technology is used
to achieve precise control of optical signal strength. Users can
easily adjust the optical signal attenuation of each channel
according to actual needs.
High reliability: The equipment usually has a fully sealed design
to prevent the influence of the external environment on the
internal optical components and ensure long-term stable operation.
At the same time, the built-in high-precision optical power meter
ensures the stability and accuracy of power monitoring.
Fast stability: The stability time of optical power control is
fast, such as the stability time of some models can reach 100
milliseconds or less, which greatly improves the test efficiency.
Easy to operate: The device is usually equipped with an intuitive
graphical user interface, multi-channel data is previewed
simultaneously, and the test status is clear at a glance. In
addition, it also supports a variety of communication interfaces,
such as RS232, USB, RJ45, etc., which is easy to connect with
computers or other devices.
