Fiber in the loop systems powering: Bellcore requirements

Power and reserve power are significant challenges to fiber in the loop (FITL) deployment. Power requirements must reflect short-term needs and the ability to move to future networks and capabilities. Major requirements in the power area are identified, together with open issues, including power system communications with remote operations systems, common optical network unit/host digital terminal (ONU/HDT) primary DC source, the impact of broadband/video service upgrades on power, and fault location for power distribution networks.<
