Individual company practices for placing fiber optic cable should supersede any conflicting instructions in this document when they do not exceed the cable''s optical and mechanical performance specifications.
It is critically important for manholes and hand holes to be built only after the plowing-in of the cable. Pre-fabricated man holes and hand holes are often utilized.
Specially designed for splicing and distributing fiber optic cables, these handholes include internal brackets or racks to manage slack loops and fiber enclosures.
Placing cables underground has the added benefits of reducing transmission losses, aiding planning consent and reduced risk of service supply loss through extreme weather. This practice covers the
This practice describes the basic guidelines for the proper sizing of handholes for use with fiber optic cable. The document is intended for personnel with prior experience in planning, engineering, or
3.3 FIBER OPTIC MANHOLES (FOMH) FOMHs) are used for communication runs and house fiber optic cable for CFX''s fiber-optic network (FON). FOMHs are 4''x4''x4'' or 4''x6.5''x6
The type of fiber optic cable and the fibers in the cable should be chosen appropriate for the type of communications system(s) being supported, the type of installation and the environment in which the
Fiber optic cable must be protected in intermediate manholes. Carefully choose racking space so that it will provide maximum protection for the cable and maintain its minimum bend radius.
Fiber optic cable sequential numbers are required at each pole location and vault wall. Sequential numbers will identify conduit length, and slack left in vaults and at poles.
