Instructions for Newly Constructed Optical Cable Lines by Telecom

This document provides procedures for installing OPGW fiber optic cables on transmission lines between 35kV and 400kV. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. Recommendations for Fiber Optic Cable Installation Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. Sections are included for project management; cable handling, testing and equipment; overhead cable placement; underground cable placement; underground enclosures; bonding and grounding; cable.

How are fiber optic cable ducts constructed

Fiber optic cable is usually (but not always) installed in an innerduct that provides mechanical protection for the fiber optic cable. Generally, the duct is available in plastic, concrete, steel, iron and so on. These ducts protect cables from environmental dangers and allow network upgrades by adding more cables. Also, the optical fibre diameter evolution from 250 to 200 and now 180μm will cable was considered very fragile and must be protected in the ground. Duct fiber optic cable refers to a specific type of optical cable specifically designed for wiring through pre laid ducts (duct materials can be selected based on geographical location, such as concrete, asbestos cement, steel pipes, plastic pipes, etc).
