2-2-2 Optical Fiber Cables (H-PCF Cables)
All of the nodes in the Optical Controller Link Network are connected in a line
(daisy-chain configuration) with H-PCF Optical Fiber Cables.
Begin connection with the rightmost connector (SL1) of the highest node in the
network and connect to the leftmost connector (SL2) in the next lower node, as
shown in the following diagram.
The nodes can be connected in any order, but connect the nodes in the order of
node addresses (i.e., node 1, node 2... node 62) as much as possible to reduce
the effect on the communications time if a wire breaks.
Always cover the unused connectors on the highest and lowest nodes in the net-
work with the enclosed Optical Connector Covers.

Refer to 2-1-1 Devices Required for Connection for details on available Optical
Fiber Cables. Refer to 2-2-3 Installing Connectors for details on connecting the
Optical Fiber Cables to the Controller Link Board.
Note
1. Always use the specified Optical Fiber Cables.
2. The maximum distance between nodes depends on the method used to at-
tach the connector to the cable.
3. In a system using Optical System Units (model numbers ending CLK11) in
Token Bus Mode (daisy chain connections), the maximum number of nodes
is 32 (i.e., node addresses 1 to 32).
Connect all the nodes in a ring using H-PCF Optical Fiber Cables.
Begin connection with the rightmost connector (SL1) of the highest node in the
network and connect to the leftmost connector (SL2) in the next lower node, as
shown in the following diagram.
The nodes can be connected in any order, but connect the nodes in the order of
node addresses (i.e., node 1, node 2... node 62) as much as possible to reduce
the effect on the communications time if a wire breaks.
