Fiber Optic Inspection at Junction Box Branch Points
First step is to make an accurate inspection of the ferrule, using a video microscope. They define a minimum baseline of quality and workmanshi for installing electrical products and systems. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance. This note also provides background information on system link configurations, test equipment and system component considerations that influence. Pull and junction boxes and FOMHs serve many purposes; their primary unction, however, is to facilitate and provide a means of pulling conductors or cables through a conduit. There are three main principles that needs to be taken in consideration for an efficient optical connection: a perfect core alignment, perfect physical contact and dirt-free connectors.
