Description

An indoor fiber optic cable is a specialized cable designed for use within buildings that features a flame-retardant, low-smoke jacket to comply with fire safety regulations. Unlike outdoor cables, which are built to withstand harsh environmental conditions and are often armored, indoor cables are more flexible and focus on safety and ease of installation in structured environments like conduits, cable trays, or ductwork.

Key characteristics

Flame-retardant jacket: The outer jacket is made of materials that are flame-retardant and can also be low-smoke zero-halogen (LSZH) to prevent the release of toxic fumes in a fire.
Flexibility: These cables are typically more flexible and have a tight-buffered construction, making them easier to manage and route within a building.
Lower tensile strength: They do not require the same level of physical strength as outdoor cables, which are built to withstand pulling, weather, and UV exposure.
Common use cases: They are used for data transmission within local area networks (LANs), data centers, and for connecting devices and networks inside a building.
Installation methods: Indoor cables can be installed in ducts, cable trays, or elevated over drop ceilings and under raised floors, but they are not designed for direct burial or exposure to the elements.
