Abstract
The utility model discloses a fireproof optical cable, which comprises a plurality of optical fibers. A cable core is formed by the plurality of optical fibers. The outside of the cable core is successively coated with a belting layer, a ceramic silicone rubber fireproof layer and a flame-retardant and oxygen-insulating outer sheath. The ceramic silicone rubber fireproof layer is excellent in fireproof and fire-resistant properties. Even if the temperature exceeds the limit of the fire endurance of the optical cable, the optical cable can still be ablated to be prepared as a hard protective shell. Due to the formation of the protective shell, flames are prevented from spreading towards the interior of the optical cable, so that the normal usage functions of the optical cable are ensured. During a fire disaster, heat outside the optical cable is prevented from being transferred to the interior of the optical cable through the flame-retardant and oxygen-insulating outer sheath. When the fire disaster is getting larger and lasts for a longer period of time, the flame-retardant and oxygen-insulating outer sheath begins foaming when the temperature reaches a certain value. After the foaming process, the thickness of the flame-retardant and oxygen-insulating outer sheath is increased and the heat insulating ability thereof is therefore improved. Therefore, the internal heat insulating ability of the optical cable is further strengthened.
