Fiber optic cable have specific classifications. Can you answer the following question with ease?
Question:
The fibers of fiber optic cables are sub-classified as which of the following:
I. General purpose (OFN for conductive, OFC for conductive)
II. Riser (OFNR and OFCR)
III. Plenum (OFNP and OFCP)
Solution:
Article 770 of the NEC governs fiber optic cable. It classifies fiber optic cable into two main types, conductive and nonconductive. Conductive fibers contain metallic materials, nonconductive do not contain any metal materials. The fibers are additionally sub-classified as general purpose (OFN for conductive, OFC for conductive), riser (OFNR and OFCR), and plenum (OFNP and OFCP) just like copper cables. Both types of fibers optic cables are permitted in the same raceway as high voltage cables.
