Product Description

AFL's Build Out Attenuators (BOA) are designed to control the power in passive optical networks. The power received by optical equipment must fall within its operating budget to ensure performance and to maintain the life of the optical receivers. These BOAs can give you the exact level of attenuation required to guarantee your network is performing within the power budget.
