Home run
Home run turns up in 2 fields: electricians, fiber optics. Here is what it means to the people in each one.
Home run in electricians
Part of a circuit running from the first box back to the panel, or the arrow on a drawing that shows it.
A home run is the section of a branch circuit from the panel to the first outlet or junction box. On electrical plans it is drawn as an arrow pointing toward the panel, labeled with the panel name and circuit number, with tick marks showing the conductors. Electricians tag home run cables at rough-in so trim goes smoothly, and a dedicated home run serves a single load such as a refrigerator or furnace.
"Label every home run with its circuit number at the panel end, I'm not ringing them out at trim."
Home run in fiber optics
A dedicated fiber run straight from the central point to one end location, with no splitter or shared path in between.
A cable or fiber path that goes directly from the main hub, central office or main equipment room to a single outlet, closet or subscriber. In FTTH, a home-run design gives each home its own fiber back to the central office, the point-to-point alternative to splitting near the customer. In buildings it means each closet or outlet has its own cable back to the main room rather than daisy-chaining.
"Every closet gets a home run back to the MDF, no splicing in the ceilings and no shared cables between floors."
