Connecting H-PCF Cable Optical Ring System Cables
node lower in the network connects to the Board's left connector. Insert the
cable's connectors fully into the Board's connectors.
• Insert the connectors completely and check that the connectors are locked be-
fore starting operation.
• If a connector becomes disconnected, the node will be unable to communicate
with other nodes in that part of the network. The network will be divided into two
and communications with the remaining nodes will be unreliable.

• Do not pull on the Optical Fiber Cable.
The maximum tension that can be applied to the cord is 10 kg (about 22 lbs)
and the maximum tension that can be applied to the cable is 50 kg (about
110 lbs).
• Do not bend the cable paste its natural bending radius. The minimum radius for
bends is 10 cm.
• To prevent the Optical Fiber Cable from being pulled too forcefully, always use
the cable mounting bracket and provide space behind the Board as shown in
the following diagram. Do not exceed the maximum tension for the cord and
cable:
Cord: 0 kg (Do not apply any tension.)
Cable: 5 kg (about 11 lbs)
• Do not place objects on top of the Optical Fiber Cable. The maximum pressure
that can be placed on the cord and cable is as follows:
Communications will continue (unreliably)
