Direct Burial Fiber Optic Cable Installation

The following methods of direct burial of fiber optic cables will be addressed.

Direct burial fiber optic cable installation.

The most common cables used for direct burial are steel armored outdoor fiber cables. Direct buried cable dbc is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any kind of extra covering sheathing or piping to protect it. To arrive at a working bend radius for cable installation multiply 15 times 15 x the cable outside diameter. Direct buried fiber optic cable installation practices are essentially the same as those used for placing copper cable.

The installation process can be very quick. Cable diameter 0 46 in 11 8 mm 15 x 0 46 in 6 9 in 177 mm. These cables feature steel tape armor so that they can be installed directly into the ground without the use of a protective conduit or duct. 1 04 it is assumed in this document that the reader is familiar with the direct burial procedure used for copper cable.

The most commonly deployed armored outdoor cable design with fiber counts from 2 to 288 fibers and up to 432 fibers for gel filled. These sturdy cables are built to resist moisture heat soil acidity and other environmental factors that could interfere with their performance. Gel free specification sheet gel filled specification sheet. They will provide reliable performance for many.

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. Fiber optic cables can also be pulled through underground ducts which protect the cables from harsh environment.
