5.1 Precautions for Laying Optical Fiber Cables
1) The distance between stations varies depending on the type of optical
fiber cable used.
SI type optical fiber cable
(Old type: A-2P-$)
SI type optical fiber cable
SI (H-PGF) type optical fiber cable
QSI type optical fiber cable
2) When connecting an optical fiber cable, the following restrictions on the
bending radius must be observed.
