See section 6.2.2 for adapter and optical fiber cable specifications.
Pay attention to the following points when you are using the panel internal
wiring type without reinforced covering (A66L–6001–0008).
Do not to bend optical fiber cable to less than a radius of 15 mm.
Do not unnecessarily twist optical fiber cable.
When securing optical fiber cable using nylon bands, do not allow the
outer covering of the cable to be deformed. (Do not tug on nylon bands.
Tugging on nylon bands applies unnecessary force on the optical fiber
cable.)
When securing optical fiber cable using nylon bands, do not allow
bending force to be applied partially.
