Choose Fiber-optic Cable for the Module
The type of fiber cable you choose to use depends on the network environment.
Consult your installation professional to determine the best type of cable to use
for your environmental conditions. Refer to the ControlNet Fiber Media
Planning and Installation Guide, publication
CNET-IN001 , for details.
Understand the Maximum Optical Power Budget
This table shows the maximum optical power budget available for different cable
types. Note that the 1786-RPFRL/B module cannot be used with
single-mode fiber.
See page 20 for formulas to determine your optical power budget.
ATTENTION: Do not discard the end cap. Use this end cap to
cover the exposed interconnections on the last repeater module on
the DIN rail. Failure to do so could result in equipment damage or
injury from electric shock.
