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 coverage, this product reduces the number of offices and meets
the operators’ demand of using less office for larger capacity.

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.
