Direct Burial Fiber Optic Cable Installation

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.

Direct burial fiber optic cable installation.

To arrive at a working bend radius for cable installation multiply 15 times 15 x the cable outside diameter. 1 04 it is assumed in this document that the reader is familiar with the direct burial procedure used for copper cable. 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. 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.

The most commonly deployed armored outdoor cable design with fiber counts from 2 to 288 fibers and up to 432 fibers for gel filled. Gel free specification sheet gel filled specification sheet. Direct buried fiber optic cable installation practices are essentially the same as those used for placing copper cable. Cable diameter 0 46 in 11 8 mm 15 x 0 46 in 6 9 in 177 mm.

The most common cables used for direct burial are steel armored outdoor fiber cables. The installation process can be very quick. The cables are plowed in or buried in a trench. These sturdy cables are built to resist moisture heat soil acidity and other environmental factors that could interfere with their performance.

They will provide reliable performance for many. Fiber optic cables can also be pulled through underground ducts which protect the cables from harsh environment.
