Rockwell Automation 1786-series ControlNet Fiber Media Planning and Installation Guide - Manual (Page 44)

Chapter 3 Guidelines for Fiber-optic Installation
Single- and multi-mode pre-terminated fiber cables for medium, long, and
extra-long distances also can be purchased that are made to order or off the shelf
from your supplier. However, keep in mind that a fiber media installation must be
certified and terminating longer distances in the field can be challenging. Trained
specialists can select the correct type of fiber cable for your environmental and
intrinsically safe area needs.
We recommend a trained specialist for installation of single- and multi-mode
cables for the 1786-RPFM, (medium), 1786-RPFRL (long-distance), and
1786-RPFRXL (extra long-distance) fiber modules.
The specialist you choose should install your cable and terminate it following the
supplier’s installation instructions. The installation should include verification
testing that provides segment length and loss at the appropriate optical
wavelength. Verification should also provide pass/fail based on the limits defined
in the fiber module users documentation or this manual.
Guidelines for Handling Fiber-optic Cable
These guidelines are designed to protect the safety of personnel who handle
fiber-optic cable. The guidelines in
Table 7 help establish an environment that
allows for the best performance from your fiber-optic system.
ATTENTION: Do not look directly into the fiber ports. Light levels may
cause damage to your eyesight. Do not view an active cable end through a
fiber microscope.
Table 7 - Guidelines for Handling Fiber-optic Cable
Guideline Description
Minimum bend radius • Observe the minimum fiber cable bend radius specified.
Skin contact • Do not touch the ends of the fiber-optic strands. The fiber can
break easily and pierce your skin.
Installation training • Train personnel on usage of the installation tools to place and
terminate fiber cable. This would include training on hand-held
tools, tension meters, optical power meters, cleaners, and
adhesives.
Installation regulations • Observe all local regulations for installation, including personal
safety equipment and the guidelines for its use.
