(4) Lateral pressure
If lateral pressure is added on optical cable, the optical cable itself distorts, internal optical fiber gets
stressed, and then transmission loss will increase. At worst, the breakage of optical cable may occur. As
the same condition also occurs at cable laying, do not tighten up optical cable with a thing such as nylon
band (TY-RAP).
Do not trample it down or tuck it down with the door of control box or others.
(5) Twisting
If optical fiber is twisted, it will become the same stress added condition as when local lateral pressure or
bend is added. Consequently, transmission loss increases, and the breakage of optical fiber may occur at
worst.

(6) Disposal
When incinerating optical cable (cord) used for SSCNET , hydrogen fluoride gas or hydrogen chloride gas
which is corrosive and harmful may be generated. For disposal of optical fiber, request for specialized
industrial waste disposal services who has incineration facility for disposing hydrogen fluoride gas or
hydrogen chloride gas.
