An outdoor enclosure for a remote terminal is designed so that a structure supporting protector modules (normally coupled between telephone lines and line cards to prevent damage from a surge in current or voltage) is easily reachable and removable. To upgrade from copper to fiber, the just-described hardware (also called "protect block") is replaced with other hardware (also called "fiber fanout enclosure") that supports adapters for receiving connectors of optical fibers. The protect block and the fiber fanout enclosure are designed to have approximately (or even exactly) the same footprint, so that they occupy at least some of the same space (before and after replacement). Reuse of the same space in this manner is advantageous over an outdoor enclosure designed to have additional space dedicated for adapters and fiber fanout enclosures to be added in future, because a more compact arrangement results from reuse of the same space.
