Variable Fiber Optic Attenuators

اتنیتور متغیر فیبر نوری


Product Code: Variable Fiber Optic Attenuators



[su_tab title=”Description”]

The Variable Attenuators are waveguide components for tunable signal leveling or reflection compensation in waveguide networks. The variable optical attenuator could continually and variably attenuate the light intensity in the optical fiber transmission. Variable fiber attenuator can help user vary the light power injected from a light source into the optical fiber.
