3. Hardware Installation

This chapter offers information about installing your ONU. If

you are not familiar with the hardware or software parameters

presented here, please consult your service provider for the

values needed.

3.1 Safety Requirement

 Make sure the GEPON service is enabled.

 Ensure that the optical ber is long enough to achieve the

desired installation place.

 Put the ONU on a sturdy table.

 Don’t open the device when the ONU is operating.

 Contact your local agent for permission if you want to

remove the chassis.

 Allow about 10cm of clearance around the ONU chassis for

heat dissipation.

Step 3. Connecting Power Adapter.

a. Connect the power adapter to the power socket on

the ONU.

b. Insert the other end into a power outlet.

3.2 Hardware Installation

Please connect the ONU to your devices as follows:

Step 1. Connecting the RJ45 network cable.

a. Plug in the RJ45 cable to 10/100/1000 GE port.

b. Plug in the other side to your host or devices.

Step 2. Connecting the ber cable.

Before connecting, please note:

Keep the optical connector and the optical fiber clean.

 Make sure the bending diameter of the fiber is more than

6cm. Otherwise, the optical signal loss may be increased.

 Cover a protective cap to guard against dust and water

when the fiber is not used.

a. Remove the protective cap of the optical ber.

b. Remove the protective cap of the ONU optical

interface (PON interface). Insert the ber into the

PON interface.

3.3 Verifying the Installation

After powering on the ONU, the Power LED will be lit and

ONU system will start to check the Optical signal. If the ONU

system receives the optical signal, the PON LED will be lit and

ONU system will start to register. If OLT and ONU register

successfully, the Link LED will be lit which means that the

connection is establishing.

Note

The PLANET GEPON ONU was designed with

PLANET OLT EPL-2220 system. If your connection

device is a third-party OLT system, the PON

connection might be unstable and malfunctioned,

due to the configurations of ONU which must

depend on the OLT settings.

If the ONU can’t work properly with OLT of other

brands, contact the third-party OLT vendor for

technical support.

3.4 Applications

The OLT device is deployed in the central ofce room. The ONU

devices are connected to the OLT device through an optical

splitter, which forms a P2MP (Point-to-Multipoint) topology, and

are connected to the switches or the devices as computers, IP

phone and IP surveillance for Triple Play service are shown in

the following gure:
