Direct Burial Fiber Optic Cable

Direct burial fiber optic cable is an underground fiber optic cable specially designed for direct buried installation with steel tape or wire armor outside. Direct burial is the most convenient way to lay optical cables. It saves the cost of pipeline and overhead installation. The cable is usually made of a plastic sheath and surrounded by a protective armor. This armored fiber optic cable protects the fiber from damage caused by rodents and other animals. In addition, the direct burial cable is also designed to be moisture-resistant, which helps prevent water from seeping into it and damaging the fibers. Direct burial cable is primarily used in direct burial in the soil or underground conduits.

direct burial fiber optic cable

Direct buried cable is placed underground without conduit. On the other hand, splices can be stored above ground in a pedestal or buried underground. These direct burial cables have good mechanical and temperature properties, compression resistance, and flexibility. Direct burial fiber optic cable is suitable for long-distance communication applications. In addition, urban areas are also suitable for direct burial methods.

Direct Burial Fiber Optic Cable Features

Save install time and labor costs

Direct burial is the most cost-effective and convenient fiber optic cable laying method and saves duct and aerial installation costs. These cables feature steel-tape armor so that they can be installed directly into the ground eliminating the need for costly protective conduit/duct installation and fiber pulls through it.

Armor fiber cable keeps rodents out

The armored construction provides rodent protection. This armored protects the fiber from damage caused by rodents and other animals.

UV, moisture, and fungus-resistant

The cable is protected by a polyethylene, UV-resistant jacket, allowing direct burial of the cable. In addition, the direct burial cable is also designed to be moisture-resistant, which helps prevent water from seeping into it and damaging the fibers.

Loose tube design

Its loose tube design offers reliable transmission performance over a broad temperature range. In addition, it also provides stable and highly reliable transmission parameters for voice, data, video, and imaging applications.

Direct Burial Fiber Optic Cable Applications

Direct burial is the most common approach in urban areas. It is a laying method in which the optical cables are directly buried underground by digging and slotting. This method does not require poles or underground ducts. Therefore, the current long-distance trunk optical cable line project and the local transmission network optical cable line mostly adopt the direct burial laying method in the suburbs. Directly buried optical cables are widely used in subways, tunnels, long-distance communications, inter-office communications networks, metropolitan area networks (MAN), local area networks (LAN), outdoor access networks, telecommunications, video, data transmission, cable TV, etc.
