Fiber Optic Products

Clearfield ® provides both build-out and in-line attenuators in all industry standard interface and attenuation values.

Fiber optic attenuators are designed to introduce a specific amount of signal loss into an optical circuit. These products provide attenuation at a mated pair connection and are used for signal budgeting and power equalization.
