1 Product Overview
1.1 Overview
With the increase of Internet users and the development of the services such as video meeting
and G-Byte file transmission, the world demands more and more network bandwidth. Optical
fiber transmission provides an effective way to meet these requirements. Through combining the
widely-used Ethernet technologies with the passive optical network (PON) technologies,
Ethernet passive optical network (EPON) can provide a good solution for
point-to-multiple-point accesses.
GONU11B ONU provide high bandwidth over a distance of 10 km, breaking through the
limitations on bandwidth and transmission distance and making the access solution more
flexible. Due to their large-scale co verage, this product reduces the number of offices and meets
the operators’ demand of using less office for larger capacity.
1.2 Introduction
GONU11B is an EPON ONU device designed with one standard 10/100Base-T Ethernet port
plus one standard 10/100 /1000 Base-T Ethernet port for subscriber access and for indoor
residential installation . It is a cost-effective GE-PON customer premise system and can provide
1000M Broadband services by connected subscriber’s gateway or computers. As compared to
other broadband access technologies such as xDSL and cable modem, Passive Optical Network
(PON) technology offers some competing advantages, including a long-term life expectancy of
the fiber infrastructure, lower operating costs through the reduction of “active” components,
support for greater distance between equipment nodes, and most importantly, much greater
bandwidth. Well satisfying the high speed access demand, GE-PON has a more prosperous
perspective.
GONU11B adopts TK3713 as main chip, which provides the core functionality of an 802.3ah
Ethernet Passive Optical Network (EPON) Optical Network Unit (ONU) solution. In addition,
the device also offers some advanced functions such as QoS, AES, FEC, and in-band OAM. A
powerful Ethernet Lookup Engine is provided to allow for traffic prioritization, local address
filtering, and statistics gathering. Forty internal FIFOs provide buffering for upstream and
downstream traffic along with 802.3ah OAM traffic. A dedicated processor provides
management control and responds to in-band OAM commands and Host Interface messages for
configuration and statistics gathering. By means of configuring personal variables accordingly,
you will get a device that will fit your application very well.

2 Hardware Installation
2.1 Safety Precautions
Make sure the GEPON service is enabled.
Ensure that the optical fiber is long enough to achieve the desired installation place.
Put the ONU on a sturdy table.
When installing the ONU on a vertical surface, you should properly fix the ONU device
and the power adapter to avoid them falling down.
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 10 cm of clearance around the ONU chassis for heat dissipation.
When an ONU device is to be installed outdoors, take lightning protection into
consideration.
2.2 Installing the ONU
2.2.1 Installing the ONU on a workbench
Put the ONU on a clean, flat, sturdy workbench. You must keep the clearance more than 10cm
for heat dissipation.
2.2.2 Installing the ONU on a Vertical Surface
You can install the ONU on a vertical surface by using the molded mounting brackets on the
bottom of the ONU chassis and two pan-head screws.
Before installing, make sure:
Make sure the screws are well fastened.
Make sure the power adapter of the ONU is firmly fixed and will not fall down from the
unit.
And then follow these processes to hang the ONU:
Step 1 Drill two holes in the wall, the holes must be in the same horizontal line and the
distance between them must be 96 mm
.
Step 2 Insert two alignment tubes into the two holes.
Step 3 Drive two pan-head screws into the alignment tubes, leaving at least 1.5 mm between
Step 4
the screw caps and the wall.
Hang the ONU on these screws through the notches on the bottom of the ONU.

2.3 Network Cable Connection
Step 1 Insert one end of the network cable (RJ-45) into the 10/100/1000BASE-T or the
10/100BASE-T interface of the ONU.
Step 2 Insert the other end of the cable (RJ-45) into the RJ-45 port on the peer device.
2.4 Fiber Cable Connection
Before connection, 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, or even signals may be unavailable.
Cover a protective cap to guard against dust and water when the fiber is not used.
Step 1 Remove the protective cap of the optical fiber.
Step 2 Remove the protective cap of the ONU optical interface (PON interface).
Step 3 Insert the fiber into the PON interface.
2.5 Power Adapter and Cable Connection
Step 1 Connect the output end of the power adapter to the power socket on the ONU.
Step 2 Insert one end of the power cable into the input socket of the power supply adapter.
Step 3 Insert the other end of the power cable into a power outlet.
Step 4 Turn on the power-switch, then check whether the POWER LED is on. If not, check the
connection between the power cable and the adapter.
2.6 Verifying the Installation
After the ONU is powered on, check whether the PON interface status LED (Link) is on. If yes,
the connection is normal; otherwise check the connection of the optical fiber.
