3-28 Connecting Your Ultra3000
Cable lengths of 32 m (105 ft) for plastic cable and 200 m (656.7 ft) for
glass cable are possible for each transmission section (point A to B).
In Figure 3.24, the second Ultra3000-SE system is located in a separate
cabinet and connected with bulkhead adapters.

Fiber-Optic Ring Connection (Example 4)
To connect the SERCOS fiber-optic cables:
1. Insert one end of a fiber-optic cable into the Receive SERCOS
connector on the Ultra3000-SE and thread the connector on finger
tight.
2. Insert the other end of the cable (from step 1) into the Transmit
SERCOS connector on the ControlLogix module/SoftLogix PCI
Card and thread the connector on finger tight.
3. Insert one end of another fiber-optic cable into the Transmit
SERCOS connector on the last Ultra3000-SE drive in the ring and
thread the connector on finger tight.
IMPORTANT
To avoid signal loss, do not mix glass and plastic
cables when connecting to a bulkhead adapter. Use
glass-to-glass or plastic-to-plastic cable on both sides
of the adapter.
IMPORTANT
Clean the fiber-optic cable connectors prior to
installation. Dust in the connectors can reduce signal
strength. For more information, refer to Fiber Optic
Cable Installation and Handling Instructions
(publication 2090-IN010x-EN-P).
