2.3.2 Connecting the Optical Fiber
Note:
When the optical fiber is not used, make sure of wearing the dust-proof cap
on the optical interface of ONU and on the optical fiber. By doing so, dust
and vapor can be prevented from contaminating the optical fiber and the
optical interface of ONU.
Do not bind parallel optical fibers too tightly so that the optical fibers can
be prevented from being dysfunctionally crushed.
Before ONU connects the optical fiber, you should get the optical fiber
well installed. The detailed procedure of installing the optical fiber is shown
below:
(1) Screw off the dust-proof cap.
(2) Connect the connector of the optical fiber to the optical interface
on the wall.
2.3.3 Connecting the Power Adapter and the Power Line
(1) Connect the output terminal of the power adapter to the input
terminal of the ONU’s power source.
(2) Insert the other end of the power line into the socket of the power
source.
(3) Check whether the POWER (PWR) LED is on. If the LED is
always on, it means the power source runs normally; if not, please
check whether the connection between the power line and the
power adapter is correct.
2.3.4 Checkup After Installation
(1) Check whether the LOS LED is on after ONU is powered. In case
the LED is on, meaning the received light is too poor, please check
whether the optical fiber is correctly connected.
