What kind of fiber is ofnr fiber?

　　OFNR fiber refers to OFNR (optical fiber Nonconductive) Riser) fiber optics with fire rating standards. Here is a detailed explanation of OFNR fibers:

　　I. Definition and Identification

　　OFNR is a fiber optic cable fire protection label, the full name is Optical Fiber Nonconductive Riser, which means "non-conductive vertical type of fiber optic". This logo represents the fire performance level of the fiber optic cable in a specific application scenario.

　　Application scenarios

　　OFNR fiber optics are mainly suitable for installation in non-conductive vertical corridors or vertical channels. For example, in vertical wiring systems in high-rise buildings, data centers, office buildings, etc., OFNR fiber optics can provide effective fire protection and prevent fire from spreading in the building's ascending channel.

　　III. Fire performance

　　OFNR fiber has high fire resistance. In the event of a fire, it can stop the spread of the fire to a certain extent, winning precious time for escape and rescue. At the same time, OFNR fiber also has flame retardant, anti-aging, anti-ultraviolet and other characteristics, which can maintain stable tranSMission performance in harsh environments.

　　IV. Material and structure

　　OFNR fibers are usually made of flame retardant materials such as PVC or LSZH (low smoke and halogen free). These materials have the advantages of low smoke, low toxicity, low corrosion and high flame retardancy, which can reduce the emission of smoke and toxic gases in the event of a fire, and reduce the harm to personnel and the environment.

　　V. Selection and application

　　When selecting an OFNR fiber, it needs to be determined according to the specific application scenario and the requirements of local building codes. At the same time, it is also necessary to consider the transmission performance, attenuation, bandwidth and other parameters of the fiber to ensure that the selected fiber can meet the actual needs. During the application process, relevant installation and maintenance specifications need to be followed to ensure that the transmission performance and fire protection performance of the fiber are fully exerted.

　　In summary, OFNR fiber is an optical fiber that meets specific fire rating standards and is suitable for installation in non-conductive vertical corridors or vertical channels. It has high fire performance, flame retardant, anti-aging, anti-ultraviolet and other characteristics, and can maintain stable transmission performance in harsh environments. When selecting and applying, it is necessary to select and install according to specific needs and specifications.
