What does the acronym OFNR signify?

• A. Non-Conductive Riser
• B. Optical Fiber Non-Return
• C. Non-Conductive Repeater
• D. Outer Fiber Neutral Return

Answer: (A)

OFNR describes a fiber optic cable's construction and where it can be used. It stands for Optical Fiber Non-Conductive Riser. The non-conductive part means the jacket has no metal that could conduct electricity, reducing electrical hazards and interference. The riser designation indicates the cable is rated for vertical runs between floors in building shafts, with appropriate flame-retardant properties to slow fire spread. Among the choices, the phrase Non-Conductive Riser captures those two essential aspects—the non-conductive jacket and its intended use in riser spaces. The other terms don’t align with standard fiber optic ratings.
