For details, check the specifications of the cable to be used.
(b) Laying an optical fiber cable
When laying an optical fiber cable, do not directly touch an optical fiber core of a
plug or jack, and prevent dirt or dust from attaching it.
If oil from hand, dirt, or dust is attached, transmission loss may increase, resulting
in failure at data link.
In addition, do not remove the cover from a connector of the module before
installing an optical fiber cable.
