3. Preparation of Interface Cables and Terminals
56
The optical fiber cables should be 3 m longer than the length needed to maintain the
device. The extra part should be wound near the device. When optical fiber and
other interface cables are used together, pay attention not to apply excessive stress
on the optical fibers.
Always have some extra optical fiber cables on hand.
For details about interfaces, see B. Physical Specifications of Network Interfaces.
