Best practices guide for remote line power

摘要

Telecommunications networks have been transitioning from a centralized to distributed architecture. With Fiber extending deeper into the wireline network and Small Cells becoming a more prevalent means for targeting hard-to-reach subscribers, there has been significant growth in the number of network elements located far from the central switching office. The sheer quantity of network devices increases the number of locations requiring power. Conventional power solutions, where AC is delivered by the utility to the site and then converted to the proper voltage for the equipment, has proven to be capital-intensive and expensive to maintain (especially if battery backup is required). Moreover, deployment schedules are complicated by the need to manage multiple electrical utilities supplying AC power to the sites. This paper provides an overview of how to plan, engineer, and deploy a remote line powered (RLP) network. It provides details on how RLP works, how far it can reach, and how to qualify cable pairs for use in these circuits. The paper concludes with a summary of best practices for deploying Remote Line Power.
