2.2 Quick Installation
1. Connecting the optical fiber cable to the unit.
a) Remove the protective cap of the optical fiber.
b) Clean the end of the optical fiber with an optical fiber end cleaner.
c) Remove the protective cap of the ONU optical interface (PON interface). Connect the fiber
to the PON port on the unit.
Note: When measuring the optical power before connecting to the ONU, it is recommended to
use a PON Inline Power Meter.
While connecting, please note:
⚫Keep the optical connector and the optical fiber clean.
⚫Make sure there are no tight bends in the fiber and that the bending diameter is greater than
6cm. Otherwise, the optical signal loss may be increased, to the extent that signal may be
unavailable.
⚫Cover all optic ports and connectors with protective cap to guard against dust and moisture
when the fiber is not used.
2. Apply power to the unit. Push the power button.

3. After the ONU is power ON, Indicators should light up as for normal operation. Check whether
the PON interface status LED (PON) is on continuously. If it is, the connection is normal;
otherwise there is either problem of the physical connection or the optical level at either end. This
may be caused by either too much or too little attenuation over the optical fiber. Please refer to
the Layout Description section of this installation manual for normal LED activity.
4. Check all signal levels and services on all the ONU communication ports.
Unit Installation Adjustment
Installing the ONU on a horizontal surface (Bench top)
Put the ONU on a clean, flat, sturdy bench top. You must keep the clearance for all sides of the
unit to more than 10cm for heat dissipation.
Installing the ONU on a vertical surface (Hanging on a wall)
You can install the ONU on a vertical surface by using the mounting holes on the bottom of
the ONU chassis and two flat-head wood screws.
a) Insert the screws into the wall. The screw positions must be in the same horizontal line and the
distance between them must be 145mm. Reserved at least 6mm between the screw caps and the
wall.
b) Hang the ONU on the screws through the mounting holes.
