A building has six floors plus a basement. Each floor is 929 sq m (10,000 sq ft) and has approximately 50 CATV outlets respectively. There is a single hardline trunk cable installed from the basement headend passing through the telecommunications room (TR) on each floor. In order to maintain the LEAST signal loss passing through each telecommunications room (TR) to the next telecommunications room (TR), what device should you specify for use within each telecommunications room (TR)?

A directional coupler is the best choice to maintain the least signal loss passing through each TR to the next TR. Directional couplers allow one signal to pass through in one direction while coupling a small portion of that signal in a different direction. This allows for minimal signal loss while distributing the signal to multiple outlets. Splitter, multiport tap, and combiner all introduce more signal loss compared to a directional coupler.
