1.7.1 Applications for FN2013 and FN2014 modules
The diagrams below show typical applications for the FN2013 and FN2014. Class B
networks are shown; for class X, two of every device are required and must be
connected in a parallel (redundant) network. Fiber-optic cables L1 and L2 are
interchangeable. L1 does not always have to be connected to L2. All fiber-optic cables
in the diagrams below are connected with two fibers between the FN2013/14 modules.
Mixing of single-mode and multi-mode fibers is not permitted.
Connect the EF1 port on FN2013 or FN2014. An external terminating resistor is not
necessary because there is an internal 120 Ω terminating resistor installed at the EF1
port.
