4 ControlNet Modular Repeater Medium Distance Fiber Module
Publication 9904-IN011A-EN-P - October 2000
About the Fiber Module
Use this module when a medium-distance (distances of 3000m/ 9843ft) fiber link is
required between two ControlNet products. This fiber link provides ground
isolation between nodes and is less susceptible to noisy environments than
traditional copper media.
The module provides:
•
two fiber channels
•
activity LED indicators for each fiber channel
Figure 1 Components of the Module
IMPORTANT
The distance that can be supported is dependent on the quality
of the fiber, number of splices, and connectors. The total loss of
the fiber link must be less than 13.3 dB.
