Which cable runs vertically between floors to connect backbone paths in a building?

• A. Backbone Cable
• B. Conduit
• C. Riser Cable
• D. Distribution Cable

Answer: (C)

Riser cable is used for vertical runs between floors to connect backbone paths in a building. The term “riser” denotes the vertical portion of the cabling that links the main backbone paths from one floor to another, typically routed through dedicated riser shafts and floor openings. These cables are designed for inter-floor vertical installations and must meet fire-safety requirements, with proper firestopping where they pass between floors. Backbone cable describes the main high-capacity links, not specifically defined as the vertical inter-floor path. Distribution cable carries signals from the distribution point to end-user outlets on a floor. Conduit is a raceway used to enclose cables, not a type of cable itself.
