Introducing the OMC
This chapter introduces the OMC and the ways you can manage the OMC.
1.1 Overview
The OLT-2300 is a manageable optical line terminal (OLT), which is capable of providing
network access to customers at distances up to 20 km.
The OLT-2300 allows service providers to easily implement FTTH (Fiber To The Home)
infrastructure offering reliable high-speed network access to their subscribers over optical
fiber through ONUs (Optical Network Units).
The following shows an example network.
Figure 1 Network Example
The OMC-2301 (GEPON OLT Management Card) centralizes the management of all of the
GEPON OLT line cards. You can configure and maintain the OLT line cards through the OLT
management card; thus eliminating the need to connect to each line card individually.
With its built-in web configurator, managing and configuring the OMC is easy. In addition, the
OMC can also be managed via Telnet, a terminal emulator program on the console port, or by
third-party SNMP management.
1.2 Applications
In the following figure shows an FTTH (Fiber to the Home) examples using the OLT-2300.
The OLT-2300 is located at the Central Office (CO) and connected to the Internet. Three
ONUs at the residential homes connect to a fiber port on the OLT-2300 through a fiber splitter.
