Generally, the materials and constructions of indoor/outdoor fiber optic cables prohibit them from being directly buried. Unlike outdoor-only fiber optic cables (also known as OSP for Outside Plant), the jacket materials used for indoor/outdoor cables enable them to pass flammability tests for indoor use, such as those for riser and plenum applications. Outdoor-only cables typically use harder materials and have other qualities preventing them from passing indoor flammability tests. Additionally, outdoor-only cables are not rated, meaning they have not passed any flammability tests 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 labeled “direct bury” in their specifications 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 both long-term outdoor and indoor use.
Yes! We are a global leader in the manufacturing of a wide variety of cable products, including wireless cable, copper cable solutions, specialty cable like transit and ribbon cable, and coaxial cables for industrial applications and beyond.
Cables used in optical fiber networks are generally tested using three key methods.
Choosing the right cable depends on your bandwidth needs, distance, environment, and whether you need multimode or single-mode fiber. For outdoor runs, loose tube constructions offer better protection, while indoor spaces may require plenum-rated or low-smoke jackets for physical safety and code compliance.
We specialize in high-performance fiber optic solutions built for long-term reliability and security. Our Fiber Optic Selection Guide will help you compare options quickly—it’s designed to simplify your decision and match the right cable to your application.
