In-line attenuators are used for reducing the optical power in fiberoptic networks. On the one hand, this is necessary for many test setups, on the other hand some transmission systems require an adjustment of the fiber-optic attenuation to the system’s dynamic. Inline attenuators are passive components which can be operated in both directions.
In many applications,in-line attenuators present an optimum, cost-efficient alternative to the combined use of intermediate attenuation connectors and normal patchcords,
and simultaneously reduce the number of required coupling locations.
The in-line attenuators are manufactured using an optimized Fused Biconical Taper (FBT) technology ensuring optimum per formance parameters and high long-term stability.
