A fixed attenuator is a precision optical device with a fixed amount of fiber attenuation. The attenuation of optical power is achieved according to the pre-designed attenuation of the line. Products are used in a variety of fiber optic transmission lines.
It is suitable for network engineering, such as intelligent monitoring system,
intelligent optical fiber cell network construction, etc.
