Direct Burial Fiber Optic Cable Installation

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

Direct burial fiber optic cable installation.

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. Direct buried fiber optic cable installation practices are essentially the same as those used for placing copper cable. Gel free specification sheet gel filled specification sheet.

The most common cables used for direct burial are steel armored outdoor fiber cables. The cables are plowed in or buried in a trench. 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 burial underground fiber optic cable lets you bury communications and transmissions systems underground without requiring additional protection.

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. Cable diameter 0 46 in 11 8 mm 15 x 0 46 in 6 9 in 177 mm. They will provide reliable performance for many. To arrive at a working bend radius for cable installation multiply 15 times 15 x the cable outside diameter.

The installation process can be very quick. The following methods of direct burial of fiber optic cables will be addressed.
