Can a fiber optic splitter be powered by a dedicated power line

Can a fiber optic splitter be powered by a dedicated power line

Unlike active networking equipment, optical splitters require no electrical power and perform signal distribution entirely through optical technology. A PoF optical power splitter is a network device designed to distribute optical data signals together with centralized DC power to multiple downstream. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. Conversely, it can also combine multiple signals into one. [pdf]
