Optical Fiber Nonconductive Plenum (OFNP) cable is a special type of cable designed to be used in ducts, plenums, and other spaces used for environmental air. It is specifically designed to meet fire-resistant and low-smoke-producing characteristics as required by certain building codes.
OFNP cable is made of a material that has been tested and approved by the National Fire Protection Association (NFPA). This material is designed to reduce the amount of smoke produced when the cable is exposed to high temperatures or flame. The cable is also designed to be non-conductive, meaning it will not carry an electrical current. This helps to reduce the risk of a fire caused by an electrical short.
In addition to its fire-resistant properties, OFNP cable is also designed to be flexible and easy to install. It is usually a single-stranded cable with a jacket that is designed to be resistant to heat, moisture, and other environmental elements. This makes it ideal for use in plenums and other spaces where there may be a high level of moisture in the air.
Finally, OFNP cable is typically rated for use in plenums and other spaces up to a certain temperature. This rating is used to ensure the safety of the cable and the surrounding environment. This is especially important in plenums, as high temperatures can cause the cable to melt or ignite.
Overall, OFNP cable is a special type of cable designed for use in plenums and other spaces used for environmental air. It is designed to meet fire-resistant and low-smoke-producing characteristics as required by certain building codes. It is also flexible, easy to install, and rated for use in plenums up to a certain temperature.
