(3) When laying the optical fiber cable, do not touch the fiber core of the cable
connector or module connector, or let dirt or dust collect on it.
If oil from the hands, dirt or dust should adhere to the core, the transmission loss will
increase, causing a malfunction in the data link.
Also, do not remove the cover from the module connector until an optical fiber cable
is connected.
(4) When attaching or detaching the optical fiber cable to/from the module, hold the
cable connector securely with the hands.
(5) Connect the cable connector and module connector securely until you hear a "click"
sound.
