Although special characteristics of optical fibers call for care in connecting
optical devices, laying optical fiber cables basically does not differ from laying
wire cables. All OMRON PCF Cables and the 3G5A2-PF101 APF (length: 1
m) Cable come with connectors attached. Connectors for all other APF
Cables must be assembled by the customer. Note the following precautions

There is no reason that a Remote I/O System must remain restricted to either
wired or optical communications. PCs support multiple Masters, some of
which can be Wired and some of which can be Optical.
Although the number of Subsystems supported by each PC is limited, each
Subsystem can be considered independently from the others as long as the
total capacity of the PC is not exceeded. It is important to note that although
both Wired and Optical Masters can be controlled by the same CPU Unit,
Optical and Wired Remote I/O Units cannot be combined in the same Sub-
system, i.e., Optical Masters can be connected only to Optical Slaves, Opti-
cal I/O Units, and I/O Link Units; Wired Masters can be connected only to
Wired Slaves and Remote Terminals.
In the following example, two CPU Racks are used. The one in the upper left
corner controls two Remote I/O Subsystems, one Wired and one Optical.
The Optical System contains an I/O Link to the other CPU Rack (at the right),
which has one Remote I/O Subsystem controlled by it.
The Optical I/O Units, Slave Rack, and Expansion I/O Rack beneath the CPU
Rack at the right are controlled through the Optical Master on this CPU Rack.
Note that if there was no Master on this Rack and the Optical I/O Units and
Slave Rack were connected through the I/O Link Unit, they would become
the last Units in the Optical Remote I/O Subsystem controlled by the CPU
Unit at the upper left, and be controlled by it.
Always turn the power off to the Link Adapter when connecting or dis-
connecting an optical fiber cable.
Always hold the connect when disconnecting an optical fiber cable;
never pull on the cable.
APF and PCF connectors are designed to be inserted only in one direct;
do not try to force them in the wrong way.
Insert APF and PCF connectors until they lock into position.
Always place the protective caps on unused Link Adapter modules.
If dirty, clean connectors gently with a tissue or sanitary cotton, using
ethyl alcohol if necessary. Do not use any solvent other than ethyl alco-
hol.
Do not allow heavy objects to fall on optical cable or otherwise subject it
to excessive shock or strain.
