Direct Burial Fiber Optic Cable Installation

Direct burial underground fiber optic cable lets you bury communications and transmissions systems underground without requiring additional protection.

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. They will provide reliable performance for many. 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.

Fiber optic cables can also be pulled through underground ducts which protect the cables from harsh environment. These sturdy cables are built to resist moisture heat soil acidity and other environmental factors that could interfere with their performance. 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. To arrive at a working bend radius for cable installation multiply 15 times 15 x the cable outside diameter.

The following formulas may be used to determine general guidelines for installing corning cable systems fiber optic cable. Gel free specification sheet gel filled specification sheet. The most common cables used for direct burial are steel armored outdoor fiber cables. The installation process can be very quick.
