OFCR designates optical fiber conductive riser cable, a conductive fiber optic cable rated for vertical riser runs between floors, with fire performance that limits flame spread.
OFCR designates optical fiber conductive riser cable, combining the conductive optical fiber classification with a riser rating. Riser-rated cable is built to limit the spread of flame from floor to floor, suiting it to the vertical pathways that run between the floors of a building. This is a higher level of fire performance than general purpose but below the strictest plenum requirements.
Because vertical riser shafts can act as channels for fire to travel between floors, cable installed in them must resist propagating flame along its length. The OFCR designation identifies conductive optical cable that meets the riser fire-performance requirement, making it appropriate for the between-floor runs that connect a building's fiber communication systems.
In commercial and industrial facilities, optical fiber conductive riser cable carries fiber communication through vertical pathways while meeting flame-spread requirements. Selecting the correct class for both the conductive type and the location is part of building a compliant fiber system.
Because a riser shaft can act as a path for fire between floors, the flame-spread performance behind the riser rating is essential, which is why OFCR is the appropriate conductive optical choice for the vertical runs connecting a building's systems.
At Windy City Wire, the focus on fiber optic cable for commercial communication includes riser-rated classes like OFCR. Supplying cable carrying the appropriate designations helps commercial facilities apply the right optical product for between-floor riser runs.
