Generally, the materials and constructions of indoor/outdoor fiber optic cables prohibit them from being directly buried. Unlike outdoor-only fiber optic cables (also called OSP for Outside Plant), the jacket materials used for indoor/outdoor cables must help the cable pass the appropriate flammability tests for indoor use, such as plenum and riser. Outdoor-only cables typically use very robust (harder) materials and have other qualities that prevent them from passing indoor flammability tests. Additionally, outdoor-only cables are not rated, meaning they have not passed any flammability test and cannot be used indoors per the U.S. National Electrical Code. Burying a cable can also crush it, so it is typically recommended that only cables that state “direct bury” in their characteristics be buried.
Hanging an indoor/outdoor fiber optic cable is acceptable. This can be done with a lashing machine or UV-resistant tie-wraps for very short runs. Indoor/outdoor fiber optic cables should be UV-resistant and have a fungicide in the jacket material. This ensures that regardless of the cable’s jacket color, it can be installed for long-term outdoor use as well as indoor use.
Choosing the right cable depends on your environment, bandwidth needs, distance, and whether you need single-mode or multimode fiber. For outdoor runs, loose tube constructions offer better protection, while indoor spaces may require low-smoke or plenum-rated jackets for code compliance and physical safety.
