Fiber Optic Extender interface cable
Series 8 has the specific cable type which must be used for each I/O family.
ATTENTION
The proper interface cable must be used for Series 8 topology. Use of the
incorrect cable results in faulty and/or corrupted IOL communication.

Fiber optic cable - length factors
The maximum run of the fiber optic cables is limited by the optical power budget of 8db.
Standard cables support 1.5 Km while premium cable supports 2 Km runs.
FOE topologies
Daisy chain topology
A daisy chain topology allows the remote I/O connection to be extended and can be
utilized several times, if maximum flight delay times of data passing between the C300
controller and I/O are not exceeded.
When Series 8 daisy chaining is performed the electrical port requires
no interface cable to be attached. This applies if:
• daisy chaining Series-8 link traffic, and
• I/O is not present at the repeating location.
A repeater function also extends the remote I/O similar to the daisy chain technique, but
relies on the optical ports of two FOE modules to provide the interconnection.
