4) 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.
5) When attaching or detaching the optical-fiber cable to/from the module,
hold the cable connector securely with the hands.
6) Connect the cable connector and module connector securely until you
hear a "click" sound.
7) Please wire IN/OUT of the connector for the cable correctly.
Please do loopback test, the set confirmation test, and the bureau order
confirmation test after wiring.
It might be generated that a baton abnormal passing cannot be generated
when miswiring and the downed bureau which cannot do the loop back of
an arbitrary bureau do the row again even by the reclosing of the power
supply.
