Definition of Direct Buried Fiber Optic Cable

Direct Buried Fiber Optic Cable this is the type of fiber cable which is buried underground without any covering or sheathing.  It is just buried direct without any kind of protection.  The research showed that most of the Direct Buried Fiber Optic Cables are built to tolerate specific conditions such as the moisture, heat, soil acidity, and conductivity. Consequently, they have unique characteristics that make the cable to cope with the conditions. 

Description of Direct Buried Fiber Optic Cable

Direct buried cables are buried under the ground without separate coverings, and therefore they might face extreme conditions, for example changing temperatures and moisture. Installation environment dictates the needed level of protection in these cables.

Nestor Cables range of cables includes a wide selection of durable direct buried cables to challenging installation conditions: from classic cables with a central tube or stranded loose tube construction to new innovative fiber optic cables with flexible construction.

How deep it’s buried 

Underground cables are pulled in a conduit that is buried underground, usually 3-4 feet (1-1.2 meters) deep to reduce the likelihood of accidentally being dug up.

Direct-buried cable (DBC) is a kind of communications or transmissions cable which is specially designed to be buried under the ground without any kind of extra covering, sheathing, or piping to protect it.

Most direct-buried cable is built to specific tolerances to heat, moisture, conductivity, and soil acidity. Unlike standard telecommunications and power cables, which have only a thin layer of insulation and a waterproof outer cover, DBC consists of multiple layers of heavy metallic-banded sheathing, reinforced by heavy rubber covers, shock absorbing gel, wrapped thread-fortified waterproof tape, and stiffened by a heavy metal core.

Dielectric, steel tape or steel wire armored cables suitable for direct burial.Cables suitable for direct burial are supplied in a variety of constructions depending on the severity of the environment in which they are to be installed. For example, cables can be dielectric, steel tape or steel wire armored, protected against rodents or any other forms of potential mechanical damage. Depending on the application various internal constructions are available, such as Central Tube, Stranded Loose Tube, Flexible and Spiral Space. All cables can be supplied in a wide range of fiber types and fiber counts. Any specific requirements can be addressed upon request.               

Conclusion

Direct Buried Fiber Optic Cable has created a lot of job opportunities to many youths worldwide. This is because people are being employed to dig those tunnels. Consequently, it has improved the communication networks. Today, someone can effectively communication with someone else in long distance apart.
